1.5 AIS – Automatic Identification System
AIS is an identification system that uses VHF communication to
transmit and receive AIS data. AIS operates primarily on two
dedicated VHF channels, AIS 1 – 161,975 MHz and AIS 2 – 162,025
MHz. Where these channels are not available regionally, the AIS can
be set to alternate designated channels.
The AIS mobile station broadcasts the vessel's position, speed and
course over ground as well as static and voyage related information.
Short safety related text messages can be sent between vessels or
broadcast from shore based AIS stations or Aids to Navigation like
buoys and lighthouses. The on-board installed mobile station is
designed to operate automatically and as a stand-alone unit. When not
transmitting, the mobile station listens for position information from
other vessels or shore based stations.
Seatex AIS 100 Instruction Manual, rev. 5 General information
4
Figure 1 Elements in an AIS system
The system broadcasts data using the SOTDMA (Self-organised Time
Division Multiple Access) data protocol. Each minute is divided into
4500 time slots, enabling simultaneous transmission of up to 500
stations.
Coverage
The system radio coverage range is similar to other VHF applications
and is dependent on the height of the antenna. The propagation differs
from that of a radar, due to the longer wavelength, so it is possible to
"see" around bends and behind islands if the landmasses are not too
high. A typical value to be expected at sea is 20 nautical miles.

AIS information content
AIS type of information is exchanged automatically between vessels,
vessels and shore based stations and vessel and Aids to Navigation
like buoys and lighthouses. The information transmitted by the AIS
mobile stations is grouped in four categories:
Static Data
• MMSI (Maritime Mobile Service Identity) number
• Call sign and name
• IMO number
• Length and beam
• Type of ship
• Location of position fixing antennas on the ship
Voyage Related Data
• Ship's draught
• Hazardous cargo type
• Destination and ETA (at Master's discretion)
Dynamic Data
• Position with accuracy indication and integrity status
• Time in UTC
• COG (Course over ground)
• SOG (Speed over ground)
• Heading
• Navigational status
• Rate of turn
Safety-related Messages
• Reading and writing short safety related messages
Data reporting and transmission rates
AIS data as stated above is autonomously sent at different update rates
and thus reporting rates are dependent on the ship's navigational
mode. Dynamic information is dependent on speed and course
alteration while static and voyage related data are transmitted every 6
minutes or on request. Thus fast ferries will report their navigational
data at a higher update rate than ships at anchor.
Seatex AIS 100 Instruction Manual, rev. 5 General information

Type of Ship Reporting
Interval
Ship at anchor 3 min.
Ship 0 to 14 knots 12 sec.
Ship 0 to 14 knots and changing course 4 sec.
Ship 14 to 23 knots 6 sec.
Ship 14 to 23 knots and changing course 2 sec.
Ship > 23 knots 3 sec.
Ship > 23 knots and changing course 2 sec.
All data input to the AIS mobile stations is based on the NMEA 0183
data protocol. Messages sent on VHF are based on the AIS data
protocol, which defines several Message Types containing different
types of information.
1.6 System components
The Seatex AIS 100 system consists of the following units:
Figure 2 AIS 100 system components
Seatex AIS 100 Instruction Manual, rev. 5 General information
7
AIS 100 Minimum Keyboard and Display (MKD)
The MKD unit provides a simple user interface to the mobile station.
The keypads on the MKD can be used to navigate between dedicated
menus used for configuration and display of vessel navigation data.
Text messages can also be entered into the MKD and transmitted to
other vessels or shore based AIS stations providing warnings or other
relevant navigation information. Thus the MKD provides basic
presentation of configuration data, position data and text messages. If
the AIS has been interfaced to the on-board ECDIS system or radar
the information displayed on the MKD can also be displayed on an
AIS compatible ECDIS or ECS systems.
AIS 100 mobile station
The mobile station incorporates two VHF receivers, configured to
operate on the predefined AIS frequencies for the region, one VHF
transmitter transmitting on all required frequencies and one DSC
receiver. The mobile station also incorporates a GPS receiver and a
processor. The internal GPS receiver, which is capable of receiving
differential corrections for increased position accuracy, is used for
time synchronisation and as a backup position sensor. For AIS data
transmission, the Self Organised Time Division Multiple Access
(SOTDMA) data protocol is used. SOTDMA enables a large number
of vessels to receive and transmit AIS data at the same time.
Front LED indicators
The LED indicators on the front of the mobile station can be used to
monitor status as well as data reception and transmission.

AIS 100 connection box
The connection box is used to connect to external sensors main
position sensor, heading sensor and rate of turn sensor (when
available). These sensors are mandatory while interfaces to electronic
hart systems and long range communication systems, are optional.
AIS compatible ECDIS/ECS systems are interfaced to the AIS
through serial line communication. Power is supplied to the AIS
mobile station through the connection box.
AIS 100 VHF antenna
The VHF antenna is used for VHF communication. The antenna is
connected to the mobile station using cables with attenuation less than
3 dB.
AIS 100 GPS antenna
The GPS antenna is an L1 antenna receiving signals from all visible
satellites. The antenna is hermetically sealed and the cable used to
connect the GPS antenna to the mobile station should be of a quality
that ensures minimum loss of signal, i.e. less than 20 dB.

2 OPERATION
2.1 Introduction
The AIS should always be in operation. It is recommended not to
switch off the AIS during port stays in order to provide information to
port authorities. In areas where piracy occurs, the master may switch
of the transmitter. If the transmitter is switched off, static data and
voyage related information will be stored.
2.2 Operational modes
After the unit has been installed and configured it operates
automatically without any user intervention. The mobile station has
three operational modes:
• Autonomous and Continuous mode
• Assigned mode
• Polled or Controlled mode
2.2.1 Autonomous and continuous mode
In the Autonomous and Continuous mode the mobile station
automatically defines its own reporting rate in accordance with its
navigational mode, speed and course. The unit also selects its own
data transmission slots. This is the normal mode for operation in all
areas but the mode may be switched to/from Assigned mode or Polled
or Controlled mode by a competent authority via a base station on
shore.
2.2.2 Assigned mode
A competent authority responsible for traffic monitoring may
remotely set transmission intervals and/or time slots for the vessel
mobile station. When operating in Assigned mode, the mobile station
will transmit position data on a slightly different format, AIS Message
Type 2, instead of the transmitted AIS Message Type 1. In Assigned
mode the mobile station does not change its reporting rate when
changing course and speed. Assignments are limited in time and will
be re-issued by the competent authority when needed. Thus, Assigned
mode only affects the transmission and not the reception of position
reports.
Seatex AIS 100 Instruction Manual, rev. 5 Operation
10
2.2.3 Polled or controlled mode
In this mode the mobile station will automatically respond to
interrogation messages from a ship or competent authority. The
response is transmitted on the channel where the interrogation
message was received. Operation in Polled or Controlled mode does
not conflict with operation in the other two modes.
2.3 Malfunction and fallback arrangements
The mobile station has built-in integrity testing to continuously verify
own operational status and notify user and external equipment if any
malfunction is detected. Part of this test monitors the transmitter and
receiver modules. Alarm status will be transmitted to the PI port in
addition to triggering the alarm relay.
Malfunction type Malfunction source
Tx malfunction
ID 001 Tx frequency is not locked or
Tx power is measured outside setting
SWR 3:1 malfunction
ID 002 SWR is measured to more than 3:1
ChA malfunction (RX1)
ID 003 ChA frequency is not locked
ChB malfunction (RX2)
ID 004 ChB frequency is not locked
Rx DSC malfunction
ID 005 Ch70 frequency is not locked
2.4 Mobile station initialisation
The mobile station will automatically switch on when power is
applied to the unit by connecting the power cable in the connection
box. There is no on/off switch and thus power is removed by
disconnecting the power cable in the connection box.
• After power has been applied, wait for the two-minute
initialisation period.
• At completed initialisation all LEDs will go amber.
• The mobile station is ready for operation when the GPS LED is
blinking at one-second intervals.
• The View page will appear on the MKD.

5 INSTALLATION
5.1 General
This section provides detailed information required to install the
Seatex AIS 100 system properly. The installation of the Seatex AIS
100 comprises installation of the components, cable pulling and
termination of interface cables. After connecting the different
components and applying power, the unit needs to be configured
before final tests in order to ensure proper operation of the system.
Unpacking and handling
Care should be taken when unpacking and handling the equipment. A
visual inspection should be made to ensure that the equipment has not
been damaged during shipment and that all parts are present according
to the packing list. A standard scope of supply for a basic Seatex AIS
100 system includes:
• MKD
• Mobile station with cable for connection to the MKD
• Connection box with cable for connection to the mobile station
• GPS antenna
• VHF antenna
Installation distribution
As installation costs may exceed the costs of the mobile station itself,
we recommend that most of the installation is carried out by the vessel
crew. This manual contains detailed installation instructions.
Installations that can be carried out by the vessel
crew:
• Mounting the AIS VHF antenna
• Pulling the VHF cable from the VHF antenna to the mobile station
• Applying connectors to the VHF antenna cable and connecting to
the VHF antenna
• Mounting the AIS GPS antenna
• Pulling the GPS cable from the GPS antenna to the mobile station
• Applying connectors to the GPS antenna cable and connecting to

• Mounting the AIS mobile station, the MKD unit and the
connection box
• Connecting the MKD unit to the mobile station using the supplied
cable
• Connecting the connection box to the mobile station using the
supplied cable
• Preparing cable for pilot plug from junction box to pilot location
Seatex AIS 100 Instruction Manual, rev. 5 Installation
34
• Preparing power cable from power source to the connection box
Installations that should be carried out by
authorised personnel:
• Connecting power to the connection box and applying power to
the mobile station
• Providing position interface from the vessel main GPS/GNSS
sensor to the AIS mobile station
• Providing heading interface from the vessel main heading sensor
to the AIS mobile station
• Termination of pilot plug cable in junction box
• Installation of pilot plug
• Providing other interfaces from external sensors to the AIS mobile
station
• Configuring the AIS mobile station
• Verifying that the unit works satisfactory in accordance with the
IMO requirements
In the following you will find detailed descriptions on how to install
the Seatex AIS 100.
5.2 AIS 100 MKD
Typically the MKD unit is installed in a dedicated hole in one of the
bridge consoles or fitted to the bulkhead at a place where the
information easily can be monitored by the navigator. For the physical
installation, screws can be mounted in the four holes hidden behind
the cover on each corner of the unit or used to fasten the bracket
following the MKD. Ensure enough space behind the MKD unit for
connecting the Amphenol connector properly without bending the
cable.

5.5 External cabling of data signals
Shielded twisted pair cables shall be used for the high-speed serial
data ports. The recommended wiring (the figures below are excerpts
from IEC 61162-2, ed. 1) is as shown on the drawings. The A, B and
C designation correspond with the data signals as listed in the tables
on the preceding pages. There may be several listeners (receivers) but
only one talker (transmitter). For long lines we recommend to use a
terminating resistor (120 Ohm between A' and B' at the receiving
end). Avoid stubs or make them as short as possible. The common
wire designated "C" is the signal ground reference and this wire shall
be isolated from the outer shielding. The outer cable shield shall be
continuous (unbroken) through the installation, but shall not be
terminated to any part of the receiver.
Figure 16 Talker and listener cabling – data/shield
Shielded twisted pair cable with third-wire is shown below. The
common "C" wire may be one wire of a pair of another port's common
connection wire "C", if they have the same destination.
Figure 17 Third wire cabling
When the AIS connection box is used, the cable shields will be
continuous from the mobile station to the external installation when
the external cables' shield is properly terminated in the nipples' metal
tongues.

5.6 AIS 100 VHF antenna
The range for receiving VHF signals relates directly to the height of
the antenna above sea level as well as the general on-board conditions
for reception and transmission of radio signals. For optimum AIS
radio performance the following should be taken into consideration:
VHF antenna installation
• It is recommended that the AIS VHF antenna should be placed in a
position with a minimum of 2 metres in horizontal direction from
constructions made of conductive materials.
• The antenna should not be installed close to any large vertical
obstruction and there should be a free view of the horizon through
360 degrees.
• The antenna should be installed safely away from interfering high
power energy sources like radar and other transmitting radio
antennas, preferably at least 3 metres away from and out of the
transmitting beam and there should not be more than one antenna
on the same level.
• The antenna should be mounted directly above or below the ships
primary VHF radiotelephone antenna, with no horizontal
separation and with a minimum of 2 metres vertical separation. If
located on the same level as other antennas, the distance apart
should be at least 10 metres.

Antenna cabling
• The cable should be kept as short as possible to minimise
attenuation of the signal. A double shielded coaxial cable equal or
better than RG-214 is recommended.
• All outdoor installed connectors on the coaxial cables should be
fitted with preventive isolation such as shrink stocking with glue
to protect against water penetration into the antenna cable.
• Coaxial cables should not be exposed to sharp bends, which could
change the characteristic impedance of the cable. The minimum
bend radius should be 5 times the cable diameter.
VHF antenna cable connection
The following procedure should be used for proper mounting of cable
connectors:
Figure 19 VHF and GPS antenna cable connector termination
Seatex AIS 100 Instruction Manual, rev. 5 Installation
44
VHF antenna cable lengths
Maximum cable lengths depend on the attenuation factors of the
cables used. The total attenuation of the VHF antenna cables should
be less than 3 dB for proper operation as higher attenuation will
reduce the coverage area of the mobile station. The cable connectors
must be of a type that is designed for the actual cable.
Cable type Max. length
RG214 30 metres
Low loss ½" Superflex 100 metres
5.7 AIS 100 GPS antenna
GPS antenna installation
Optimum location of the GPS antenna is important to ensure
continuously track of all visible GPS satellites used for time
synchronisation and computation of backup position fix. The
following should be taken into consideration during installation:
• The GPS antenna must be installed where it has a clear view of the
sky and thus the objective is to see the horizon freely through 360
degrees with a vertical observation of 5 to 90 degrees above the
horizon.
• Small diameter obstructions, such as masts and booms, do not
seriously degrade signal reception but such objects must not
eclipse more than a few degrees of any given bearing.
• Locate the antenna at least 3 metres away from and out of the
transmitting beam of high power transmitters (S-band radar and/or
Inmarsat systems). This includes the ship's own AIS VHF antenna
if it is located separately.

GPS antenna offset arms
Position data for the GPS antenna needs to be input to the AIS as a
part of the configuration settings. The figure below shows the offset
arms to be configured.
Figure 21 GPS antenna offset arms
GPS antenna cabling
• To achieve optimum performance, the gain of the antenna pre-
amplifier should match the cable attenuation. The resulting
installation gain (pre-amplifier gain – cable attenuation) should be
within 0 to 10 dB.
• The coaxial cable between the antenna and the AIS mobile station
should be routed directly in order to reduce electromagnetic
interference effects.
GPS antenna cable lengths
The GPS antenna cable should have a total attenuation of less than 10
dB as higher attenuation may degrade the quality and accuracy of the
position data.
Cable type Max. length
RG214 30 metres
Low loss ½" Superflex 100 metres
Applying power
After the mechanical and electrical installation is completed the
coaxial cables should be checked for short circuit between centre
conductor and shield (ground) with the antenna disconnected. If not
short-circuited, power could be applied to the mobile station.

Sealing of GPS and VHF antenna connectors
• Ensure that the outdoor antenna connectors are wrapped with
waterproof self-vulcanising tape.
• Stretch the tape to double length and start wrapping a bit down on
the cable.
• Wrap the tape all over the connectors and, if possible, seal it with
electric coating.
• An alternate way of waterproofing is to use heat shrinkable hose
with glue.
• The hose should cover the whole connector and part of the cable
and finally it should be sealed with electric coating.
5.8 Internal alarm system
The Seatex AIS 100 has a built-in alarm functionality. The alarm is
generated in different ways:
• Alarm generated by the BIIT.
• Alarm generated by the sensor part.
• Alarm generated by the MKD.
An alarm could cause different actions taken by the system, depending
on the nature of the alarm. An alarm generated by the BIIT could stop
transmission of messages. An alarm will open the alarm relay, which
can be used to trigger an external alarm. There will also be generated
an alarm message on the PI port which can be read on an MKD, if
connected, or on an external interfaced system.
There are two types of alarm messages, which can be output on the PI
and LAN port. An ALM message, e.g. $AIALM, is output when an
error situation arises. A TXT message, e.g. $AITXT, is output when
there is an indicator message. An error situation may arise if there is a
TX malfunction, while an indicator message may arise when
differential corrections are lost. The ALM LED in the front of the AIS
100 will be lit if an error situation arises.

6.5 New IEC 61162-1 sentences
This subchapter contains a description of proposed IEC 61162-1
sentences due to AIS. Reference is made to IEC 61193-2, 2001, annex
B2.
ABK – Addressed and binary broadcast
acknowledgement
The ABK-sentence is generated when a transaction, initiated by
reception of an ABM, AIR, or BBM sentence, is completed or
terminated.
This sentence provides information about the success or failure of a
requested ABM broadcast of either ITU-R M.1371 messages 6 or 12.
The ABK process utilises the information received in ITU-R M.1371
messages 7 and 13. Upon reception of either a VHF Data-link
message 7 or 13, or the failure of messages 6 or 12, the AIS unit
delivers the ABK sentence to the external application.
This sentence is also used to report to the external application the AIS
unit's handling of the AIR (ITU-R M.1371 message 15) and BBM
(ITU-R M.1371 messages 8 and 14) sentences. The external
application initiates an interrogation through the use of the AIR-
sentence, or a broadcast through the use of the BBM sentence. The
AIS unit generates an ABK sentence to report the outcome of the AIR
or BBM broadcast process.
NOTE 1 Identifies the distant addressed AIS unit involved with the
acknowledgement. If more than one MMSI are being addressed (ITU-
R M.1371 message 15), the MMSI of the first distant AIS unit,
identified in the message, is the MMSI reported here. When the
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
52
Message ID is a general broadcast (ITU-R M.1371 messages 8 or 14),
this field is null.
NOTE 2 Indication of VDL channel upon which Message ID 7 or 13
acknowledgement was received. An "A" indicates reception on
channel A. A "B" indicates reception on channel B. If not available,
field is null.
NOTE 3 This indicates to the external application the type of ITU-R M.1371
message that this ABK sentence is addressing. Also see the message
IDs listed in NOTE 4.
NOTE 4 The message sequence number, together with the ITU-R M.1371
message ID and MMSI of the addressed AIS unit, uniquely identifies
a previously received ABM, AIR, or BBM sentence. Generation of an
ABK-sentence makes a sequential message identifier available for
reuse. The ITU-R M.1371 Message ID is used to determine the origin
of the message sequence identifier number. The following table lists
the origins by message ID:
ITU-R M.1371
Message ID Message Sequence Number source
6 sequential message identifier from ABM-
sentence, IEC 61162-1
7 addressed AIS unit's message 7, sequence
number, ITU-R M.1371
8 sequential message identifier from BBM-
sentence, IEC 61162-1
12 sequential message identifier from ABM-
sentence, IEC 61162-1
13 addressed AIS unit's message 13, sequence
number, ITU-R M.1371
14 sequential message identifier from BBM-
sentence, IEC 61162-1
15 no source, field shall be null
NOTE 5 Acknowledgements provided are:
0 = message (6 or 12) successfully received by the addressed
AIS unit,
1 = message (6 or 12) was broadcast, but no
acknowledgement by the distant addressed AIS unit,
3 = message could not be broadcast,
4 = requested broadcast of message (8, 14, or 15) has been
successfully completed, late reception of a message 7 or 13
acknowledgement "addressed to own-ship" MMSI –
identified by; destination MMSI, acknowledgement source
MMSI, message sequence identifier, and message type.
Late reception means that the AIS unit did not have an
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
53
acknowledgement process active for the acknowledgement
that was received.
ABM – Addressed Binary and safety related
message
This sentence supports ITU-R M.1371 messages 6 and 12. It provides
an external application with a means to exchange data using an AIS.
The message data is defined by the application only – not the AIS.
This message offers great flexibility for implementing system
functions that use the AIS like a communications device. After
receiving this sentence, the AIS initiates a radio broadcast on the VHF
Data Link (VDL) of either message 6 or 12. The AIS will make up to
four broadcasts of the message. The actual number will depend on the
reception of an acknowledgement from the addressed "destination"
AIS. The default time between retries is 4 s. Retries will not be
attempted more frequently than 4 s. Retries stop when the appropriate
acknowledgement (See ITU-R M.1371 messages 7 and 13.) is
received. The AIS will make up to 4 broadcasts, original broadcast
plus three retires. This process could take 32 s to complete.
The success or failure of the reception of this broadcast by the
intended AIS unit is confirmed through the use of the "Addressed and
binary Broadcast Acknowledgement (ABK)" sentence formatter, and
the processes that support the generation of an ABK-sentence. The
AIS is also limited in the amount of encapsulated data that can be sent
in each slot and frame. If the length of the message would exceed five
slots, or the AIS broadcast would exceed the limit of 20 RATDMA
slot transmissions for the current frame, the AIS will return an ABK-
sentence with an acknowledgement of "2" – message could not be
broadcast.
NOTE 1 The total number of sentences required to transfer the binary message
data to the AIS unit. The first field specifies the total number of
sentences used for a message, minimum value 1. The second field
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
54
identifies the order of this sentence in the message, minimum value 1.
All sentences contain the same number of fields. Successive sentences
may use null fields for fields that have not changed, such as fields 4,
5, and 6.
NOTE 2 This sequential message identifier serves two purposes. It is both an
IEC 61162-1 "sequential message identifier field," and it is the
"sequence number" utilised by the ITU-R M.1371 in message types 6
and 12. The range of this field is restricted by ITU-R M.1371 to the
range of 0 to 3. This sequential message identifier and the destination
MMSI uniquely identifies a message. The sequential message
identifier may be reused after the "ABK" acknowledgement for that
sequence number is provided by the destination AIS unit. (See the
ABK-sentence formatter.)
NOTE 3 The MMSI of the AIS unit which is the destination of the message.
NOTE 4 The AIS channel that shall be used for the broadcast: 0 = no broadcast
channel preference, 1 = Broadcast on AIS channel A, 2 = Broadcast
on AIS channel B, 3 = Broadcast two copies of the message – one
copy sent on channel A and another copy sent on channel B.
NOTE 5 This is the content of the "binary data" parameter for ITU-R M.1371
message 6, or the "Safety related Text" parameter for message 12. The
first sentence may contain up to 48 "6-bit" symbols (288 bits).
Following sentences may contain up to 60 valid "6-bit" symbols (360
bits), if fields 4, 5, and 6 are unchanged from the first sentence and set
to null. The actual number of "6-bit" symbols in a sentence must be
adjusted so that the total number of characters in a sentence does not
exceed the "82-character" limit.
NOTE 6 To encapsulate, the number of binary bits must be a multiple of six. If
it is not, one to five "fill bits" are added. This parameter indicates the
number of bits that were added to the last 6-bit coded character. This
value shall be set to zero when no "fill bits" have been added. This
cannot be a null field.
ACA – AIS regional channel assignment message
An AIS unit can receive regional channel management information
four ways: ITU-R M.1371 message 22, DSC telecommand received
on channel 70, manual operator input, and an ACA-sentence. The AIS
unit may store channel management information for future use.
Channel management information is applied based upon the actual
location of the AIS unit. An AIS unit is "using" channel management
information when the information is being used to manage the
operation of the VHF receivers and/or transmitter inside the AIS unit.
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
55
This sentence is used to both enter and obtain channel management
information. When sent to an AIS unit, the ACA-sentence provides
regional information that the unit stores and uses to manage the
internal VHF radio. When sent from an AIS unit, the ACA-sentence
provides the current channel management information retained by the
AIS unit. The information contained in this sentence is similar to the
information contained in an ITU-R M.1371 message 22. The
information contained in this sentence directly relates to the
"Initialisation Phase" and "Dual Channel operation and Channel
management" of the AIS unit as described in ITU-R M.1371.
NOTE 1 This is used to bind the contents of the ACA and ACS sentences
together. If provided by the AIS, the ACS sentence shall immediately
follow the related ACA sentence, and both sentences shall contain the
same sequence number. The AIS generating ACA and ACS sentences
shall increment the sequence number by one each time an ACA/ACS
pair is created. After "9" is used, the sequence numbering process
shall begin again from "0". If the sequence numbers do not match, the
information contained in an ACS sentence is not related to the
information in an ACA sentence. The ACS sentence may be used to
respond to an "ACA Query-sentence" (See IEC 61162-1, § 5.3.2.).
The AIS shall respond by providing ACA/ACS pairs for each of the
stored regional operating settings. At any given time, the maximum
number of pairs is eight. When an ACS sentence is not sent following
an ACA sentence, the sequence number may be null.
NOTE 2 Value of 1 nautical mile to a value of 8 nautical miles (with a
resolution of 1 nautical mile)
NOTE 3 VHF channel number, see ITU-R M.1084, Annex 4
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces

Value of 1, bandwidth is 12,5 kHz.
NOTE 5 Value of 0, transmit on channels A and B, receive on channels A and B
Value of 1, transmit on channel A, receive on channels A and B
Value of 2, transmit on channel B, receive on channels A and B
Value of 3, do not transmit, receive on channels A and B
Value of 4, do not transmit, receive on channel A
Value of 5, do not transmit, receive on channel B
NOTE 6 Value of 0, high power
Value of 1, low power
NOTE 7 Source identifiers:

C, IEC 61162-1 AIS Channel Assignment sentence,
D, DSC Channel 70 telecommand, and
M, operator manual input.
This field should be null when the sentence is sent to an AIS.
NOTE 8 This value is set to indicate that the other parameters in the sentence
are "in-use" by an AIS unit at the time that the AIS unit sends this
sentence. A value of "0" indicates that the parameters are not "in-use,"
and a value of "1" indicates that the parameters are "in-use." This field
should be null when the sentence is sent to an AIS.
NOTE 9 This is the UTC time that the "in-use" flag changed to the indicated
state. This field should be null when the sentence is sent to an AIS.
AIR – AIS interrogation request
This sentence supports ITU-R M.1371 message 15. It provides an
external application with the means to initiate a request for specific
ITU-R M.1371 messages from distant mobile or base AIS stations. A
single sentence can be used to request, as many as, two messages from
one AIS unit and one message from a second AIS unit. The message
types that can be requested are limited. The complete list of messages
that can be requested can be found within the message 15 description
in ITU-R M.1371. Improper requests may be ignored.
The external application initiates the interrogation. The external
application is responsible for assessing the success or failure of the
interrogation. After receiving this sentence, the AIS initiates a radio
broadcast (on the VHF Data Link) of a message 15 – Interrogation.
The success or failure of the interrogation broadcast is determined by
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
57
the external application's assessment of the combined reception of the
ABK-sentence and future VDM-sentences provided by the AIS via the
Presentation Interface. After receiving this AIR-sentence, the AIS
should broadcast a message 15 within 4 s, and the addressed AIS
should take no more than an additional 4 s to respond – a total of 8 s.
NOTE 1 Identifies the first distant AIS being interrogated. Two messages can
be requested from the first AIS.
NOTE 2 Examples of messages that may be requested from a distant mobile
AIS station include:

Examples of messages that may be requested from a distant AIS base
station include:
Message 4, Base Station Report,
Message 17, GNSS Broadcast Binary Message, (all available
corrections are requested),
Message 20, Data Link Management Message,
Message 22, Channel Management.
NOTE 3 This field is used to request a message that has been further sub-
divided into alternative data structures. When requesting messages
with alternative data structures, this message subsection identifier
must be provided, so that the correct sub-division of the message data
is provided. If the message structure is not sub-divided into different
structures, this field should be null.
NOTE 4 This identifies the second distant AIS being interrogated. Only one
message may be requested from the second AIS. The MMSI of the
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
58
second AIS may be the same MMSI as the first AIS. This technique
can be used to request a third message from station-1.
BBM – Broadcast binary message
This sentence supports generation of an ITU-R M.1371 Binary
Broadcast Message (message 8) or Safety Related Broadcast Message
(message 14). It provides an external application with a means to
broadcast data, as defined by the application only – not the AIS. This
message offers great flexibility for implementing system functions
that use the AIS like a digital broadcast device. After receiving this
sentence, the AIS initiates a VHF broadcast of either message 8 or 14
within 4 s. (Also, see the ABK-sentence.)
The success or failure of the broadcast confirmed through the use of
the "Addressed and binary Broadcast Acknowledgement (ABK)"
sentence formatter, and the processes that support the generation of an
ABK-sentence. The AIS is limited in the amount of encapsulated data
that can be sent in each slot and frame. If the length of the message
would exceed five slots, or the AIS broadcast would exceed the limit
of 20 RATDMA slot transmissions for the current frame, the AIS will
return an ABK-sentence
NOTE 1 The total number of IEC 61162-1 sentences needed to transfer the
contents of the binary message to the AIS. The first field specifies the
total number of sentences used for a message, minimum value 1. The
second field identifies the order of this sentence in the message,
minimum value 1. All sentences contain the same number of fields.
Successive sentences may use null fields for fields that do not change
– such as fields 4 and 5.
NOTE 2 The Sequential Message Identifier provides a message identification
number from 0 to 9 that is sequentially assigned as needed. Note that
this is only a sequential message identifier. This is used differently
than the "Message sequence identifier" of an ABM sentence. This
identifier is incremented for each new multi-sentence message. The
count resets to 0, after 9 is used. For the contents of a message 8 or 14
requiring multiple sentences, each sentence of the message contains
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
59
the same Sequential Message Identification number. This number is
used to link the separate sentences containing portions of the same
encapsulated data. This allows for the possibility that other sentences
might be interleaved with the message sentences that, taken
collectively, contain a single message 8 or 14. This number also links
a future ABK-sentence acknowledgement to the appropriate BBM-
sentence. (See ABK, NOTE 4.)
NOTE 3 The AIS channel that shall be used for the broadcast: 0 = no broadcast
channel preference, 1 = Broadcast on AIS channel A, 2 = Broadcast
on AIS channel B, 3 = Broadcast two copies of the message – one on
channel A and another sent on channel B.
NOTE 4 This is the content of the "binary data" parameter for ITU-R M.1371
message 8 or the "Safety related Text" parameter for message 14. The
first sentence may contain up to 58 "6-bit" symbols (348 bits). The
following sentences may contain up to 60 "6-bit" symbols (360 bits),
if fields 4 and 5 are unchanged from the first sentence and set to null.
The actual number of "6-bit" symbols in a sentence must be adjusted
so that the total number of characters in a sentence does not exceed
the "82-character" limit.
NOTE 5 To encapsulate, the number of binary bits must be a multiple of six. If
it is not, one to five "fill bits" are added. This parameter indicates the
number of bits that were added to the last 6-bit coded character. This
value shall be set to zero when no "fill bits" have been added. This
cannot be a null field.
LRI – Long-Range Interrogation
The long-range interrogation of the AIS is accomplished through the
use of two sentences. The pair of interrogation sentences, a LRI-
sentence followed by a LRF-sentence, provides the information
needed by an AIS to determine if it must construct and provide the
reply sentences (LRF, LR1, LR2, and LR3). The LRI-sentence
contains the information that the AIS needs in order to determine if
the reply sentences need to be constructed. The LRF-sentence
identifies the information that needs to be in the reply sentences.
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
60
NOTE 1 This is used to bind the contents of the LRI and LRF sentences
together. The LRF sentence shall immediately follow the LRI
sentence and use the same sequence number. The requestor process
shall increment the sequence number each time a LRI/LRF pair is
created. The sequencing process shall continuously increment. After
"9" is used, the process shall begin again at "0". If the LRI and LRF
sequence numbers are different, the Long-range interrogation is not
valid.
NOTE 2 The control flag is a single character that qualifies the request for
information. The control flag affects the AIS unit's reply logic. The
control flag cannot be a null field. When the Control Flag is "0", the
AIS responds if either:
The AIS is within the geographic rectangle provided, and
The AIS has not responded to the requesting MMSI in the last
24 hours, and
The MMSI "destination" field is null.
or
The AIS unit's MMSI appears in the MMSI "destination" field
in the LRI sentence.
When the Control Flag is "1", the AIS responds if:
The AIS is within the geographic rectangle provided.
NOTE 3 This is the nine-digit number that uniquely identifies the specific AIS
that should respond. This field is null when the interrogation is for a
geographic region. When addressing a specific AIS, it is not necessary
to provide the geographic co-ordinates of the region.
NOTE 4 The geographic region being interrogated is a "rectangular" area
defined by the latitude and longitude of the north-east and south-west
corners. These fields should be null when interrogating a specific AIS.
(See note 2.)
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
61
LRF – Long Range Function
This sentence is used in both long-range interrogation requests and
long-range interrogation replies. The LRF-sentence is the second
sentence of the long-range interrogation request pair, LRI and LRF
(See the LRI-sentence.). The LRF-sentence is also the first sentence of
the long-range interrogation reply. The minimum reply consists of a
LRF-sentence followed by a LR1-sentence. The LR2-sentence and/or
the LR3-sentence follow the LR1-sentence, if information provided in
these sentences is requested in the interrogation. When the AIS creates
the LRF-sentence for the long-range interrogation reply, fields 1, 2, 3,
and 4 should remain as received in the interrogation; and field 5
(Function Reply Status) and a new checksum are added to the LRF
reply sentence.
NOTE 1 This is used to bind the contents of the LRI and LRF sentences
together. The LRF sentence shall immediately follow the LRI
sentence and use the same sequence number. The requestor process
shall increment the sequence number each time a LRI/LRF pair is
created. After 9 is used, the process shall begin again from 0. The
Long-range interrogation is not valid if the LRI and LRF sequence
numbers are different.
NOTE 2 The Function request field uses alphabetic characters based upon IMO
Resolution A.851(20) to request specific information items. Specific
information items are requested by including their function
identification character in this string of characters. The order in which
the characters appear in the string is not important. All characters are
upper case. Information items will not be provided if they are not
specifically requested – even if available to the AIS. The IMO
Resolution defines the use of all characters from A to Z, but not all of
the defined information is available from the AIS. The following is a
list of the function identification characters with the information they
request:
A = Ship's: name, call sign, and IMO number
B = Date and time of message composition
C = Position
E = Course over ground
F = Speed over ground
I = Destination and Estimated Time of Arrival (ETA)
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
62
O = Draught
P = Ship/Cargo
U = Ship's: length, breadth, type
W = Persons on board
NOTE 3 The "Function Reply Status" field provides the status characters for
the "Function Request" information. When a long-range interrogation
request is originated, the "Function Reply Status" field should be null.
The "Function Reply Status" characters are organised in the same
order as the corresponding function identification characters in the
"Function Request" field. The following is a list of the "Function
Reply Status" characters with the status they represent:
2 = Information available and provided in the following LR1, LR2, or
LR3 sentence,
3 = Information not available from AIS unit,
4 = Information is available but not provided (i.e. restricted access
determined by ship's master),
LR1 – Long-range Reply with destination for
function request "A"
The LR1-sentence identifies the destination for the reply and contains
the information requested by the "A" function identification character.
(See the LRF-sentence.)
NOTE 1 The three fields, sequence number, MMSI of responder, and MMSI of
requestor are always provided.
NOTE 2 The sequence number should be the same number as the sequence
number of the LRI and LRF sentences that initiated this reply.
NOTE 3 The characters that can be used are listed in IEC 61162-1, table 2.
Some characters in this table are the reserved characters listed in IEC
61162-1, table 1. Reserved characters may be used, but they must be
represented using the "^-method" (See IEC 61162-1, § 5.1.3.). The
individual information items shall be a null field, if any one of the
following three conditions exist:
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
63
The information item was not requested.
The information item was requested, but it is not available.
The information item was requested, but it is not being provided.
LR2 – Long-range Reply for function requests "B,
C, E, and F"
The LR2-sentence contains the information requested by the "B, C, E,
and F" function identification characters. (See the LRF-sentence.)
NOTE 1 If the sentence is used, the two fields, Sequence Number and MMSI of
responder, are always provided.
NOTE 2 The sequence number should be the same number as the sequence
number of the LRI and LRF sentences that initiated this reply.
NOTE 3 The individual information items shall be a null field if any of the
following three conditions exist:
The information item was not requested.
The information item was requested, but it is not available.
The information item was requested, but it is not being provided.
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
64
LR3 – Long-range Reply for function requests "I,
O, P, U and W"
The LR3-sentence contains the information requested by the "I, O, P,
U, and W" function identification characters (see the LRF-sentence).
NOTE 1 If the sentence is used, the two fields, Sequence Number and MMSI of
responder, are always provided.
NOTE 2 The sequence number should be the same number as the sequence
number of the LRI and LRF sentences that initiated this reply.
NOTE 3 The individual information items shall be a null field if any of the
following three conditions exist:
The information item was not requested,
The information item was requested but is not available, or
The information item was requested but is not being provided.
NOTE 4 Current number of persons on-board, including crew members: 0 to
8191.
0 = default (not available), 8191 = 8191 or more people.
NOTE 5 The characters that can be used are listed in IEC 61162-1, table 2.
Some characters in this table are the reserved characters listed in IEC
61162-1, table 1. Reserved characters may be used, but they must be
represented using the "^-method" (See IEC 61162-1, § 5.1.3.).
NOTE 6 See ITU-R M.1371:2000, table 17, parameter "Type of ship and cargo
type" for the range of valid values available for this field.

SSD – Ship Static Data
This sentence is used to enter static parameters into a shipboard AIS.
The parameters in this sentence support a number of the ITU-R
M.1371 messages.
NOTE 1 Ship call sign. A null field indicates that the previously entered call
sign is unchanged. The string of characters "@@@@@@@" are used
to indicate that the call sign is not available.
NOTE 2 The characters that can be used in the name are listed in the ITU-R
M.1371, table 14 (6-bit ASCII). Some of the acceptable characters in
this 6-bit ASCII table are reserved characters under IEC 61162-1.
They must be represented using the "^-method" (See IEC 61162-1,
section 5.1.3.). A null field indicates that the previously entered name
is unchanged. The string of characters
"@@@@@@@@@@@@@@@@@@@@" are used to indicate
that the ship's name is not available.
NOTE 3 These are the four dimensions from the bow, stern, port beam, and
starboard beam to the horizontal reference point on the ship for which
the current "position reports" are valid. The sum of A + B is the length
of the ship in metres, and the sum of C + D is the width of the ship in
metres (See ITU-R M.1371, message 5, "Reference Point for reported
position and Dimensions of Ship."). If the reference point of "reported
position" is not available, but the dimensions of the ship are available:
A = C = 0 and B > 0 and D > 0. If neither the reference point for the
reported position nor the dimensions of the ship are available: A = B =
C = D = 0 (default). Use of a null field for A, B, C, and/or D indicates
that the previously entered dimension for that parameter is unchanged.
In many cases, the ship's reference point for "reported position" will
be the location of the positioning antenna.
NOTE 4 The DTE indicator is an abbreviation for Data Terminal Equipment
indicator. The purpose of the DTE indicator is to inform distant
receiving applications that, if set to "available" the transmitting station
conforms, at least, to the minimum keyboard and display
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
66
requirements. The DTE indicator is only used as information provided
to the application layer – indicating that the transmitting station is
available for communications. On the transmitting side, the DTE
indicator may be set by an external application using this sentence.
DTE indicator flag values are:
0 = Keyboard and display are a standard configuration, and
communication is supported.
1 = Keyboard and display are either unknown or unable to support
communication (default setting).
NOTE 5 The source identifier contains the "Talker ID" of the equipment at this
location. The AIS may use the "Talker ID" to identify multiple
sources of position data and to detect a change to the reference point
on the ship.
VDM – VHF Data-link Message
This sentence is used to transfer the entire contents of a received AIS
message packet, as defined in ITU-R M.1371 and as received on the
VHF Data Link (VDL), using the "6-bit" field type. The structure
provides for the transfer of long binary messages by using multiple
sentences.
NOTE 1 The length of an ITU-R M.1371 message may be long and may
require the use of multiple sentences. The first field specifies the total
number of sentences used for a message, minimum value 1. The
second field identifies the order of this sentence in the message,
minimum value 1. These cannot be null fields.
NOTE 2 The Sequential message identifier provides a message identification
number from 0 to 9 that is sequentially assigned and is incremented
for each new multi-sentence message. The count resets to 0 after 9 is
used. For a message requiring multiple sentences, each sentence of the
message contains the same sequential message identification number.
It is used to identify the sentences containing portions of the same
message. This allows for the possibility that other sentences might be
interleaved with the message sentences that, taken collectively,
contain a single message. This field shall be a null field when
messages fit into one sentence.
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
67
NOTE 3 The AIS message reception channel is indicated as either "A" or "B."
This channel indication is relative to the operating conditions of the
AIS when the packet is received. This field shall be null when the
channel identification is not provided. The VHF channel numbers for
channels "A" and "B" are obtained by using an ACA-sentence "query"
of the AIS.
NOTE 4 The maximum string length of encapsulation is limited such that the
total number of sentence characters does not exceed 82. This field
supports a maximum of 62 valid characters for a message transferred
using multiple sentences, and 63 valid characters for a message using
a single sentence.
NOTE 5 To encapsulate, the number of binary bits must be a multiple of six. If
it is not, one to five "fill bits" are added. This parameter indicates the
number of bits that were added to the last 6-bit coded character. This
value shall be set to zero when no "fill bits" have been added. This
cannot be a null field.
VDO – VHF Data-link Own-vessel message
This sentence is used to provide the information assembled for
broadcast by the AIS. It uses the six-bit field type for encapsulation.
The sentence uses the same structure as the VDM sentence formatter.
NOTE 1 The length of an ITU-R M.1371 message may be long and may
require the use of multiple sentences. The first field specifies the total
number of sentences used for a message, minimum value 1. The
second field identifies the order of this sentence in the message,
minimum value 1. These cannot be null fields.
NOTE 2 The Sequential message identifier provides a message identification
number from 0 to 9 that is sequentially assigned and is incremented
for each new multi-sentence message. The count resets to 0 after 9 is
used. For a message requiring multiple sentences, each sentence of the
message contains the same sequential message identification number.
It is used to identify the sentences containing portions of the same
message. This allows for the possibility that other sentences might be
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
68
interleaved with the message sentences that, taken collectively,
contain a single message. This field shall be a null field when a
message fits into one sentence.
NOTE 3 This is the channel used to broadcast the AIS message. The AIS
channel field, set to either "A" or "B", indicates that the message was
broadcast. If the message is not broadcast, the "AIS Channel" field
shall be null. The VHF channel numbers for channels "A" and "B" are
obtained by using an ACA-sentence "query" of the AIS.
NOTE 4 The maximum string length of encapsulation is limited such that the
total number of sentence characters does not exceed 82. This field
supports a maximum of 62 valid characters for a message transferred
using multiple sentences, and 63 valid characters for a message using
a single sentence.
NOTE 5 To encapsulate, the number of binary bits must be a multiple of six. If
it is not, one to five "fill bits" are added. This parameter indicates the
number of bits that were added to the last 6-bit coded character. This
value shall be set to zero when no "fill bits" have been added. This
cannot be a null field.
VSD – Voyage Static Data
This sentence is used to enter information about a ship's voyage. This
information remains relatively static during the voyage. However, the
information will frequently change from voyage to voyage. The
parameters in this sentence support a number of the ITU-R M.1371
messages.
NOTE 1 Type of ship and cargo category are defined in ITU-R M.1371. The
description of ship and cargo are indicated by a number. The values
are defined in ITU-R M.1371, message 5. A null field indicates that
this is unchanged.
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
69
NOTE 2 Draught is reported in the range of 0 to 25,5 metres. The value 0 = not
available (default), and the value 25,5 indicates that the draught is
25,5 metres or more. Only values from 0 to 25,5 shall be accepted by
the AIS. A null field indicates that this is unchanged.
NOTE 3 Number of persons on-board includes the crew. The value 0 = not
available (default). The value 8191 = 8191 or more people. Only
values from 0 to 8191 shall be accepted by the AIS. A null field
indicates that this is unchanged.
NOTE 4 The characters that can be used in the destination are listed in the ITU-
R M.1371, table 14 (6-bit ASCII). Some of the acceptable characters
in this 6-bit ASCII table are reserved characters under IEC 61162-1.
They must be represented using the "^-method" (See IEC 61162-1,
section 5.1.3.). A null field indicates that the previously entered
destination is unchanged. The string of characters
"@@@@@@@@@@@@@@@@@@@@" are used to indicate
that the ship's destination is not available.
NOTE 5 The UTC time of arrival field follows the "TIME" field type described
in table 6 (IEC 61162-1). The two fixed digits of seconds are not
broadcast by the AIS and should be set to "00". The optional decimal
point and associated decimal fraction shall not be provided. The
resulting time is a number with six fixed digits, "hhmm00". Leading
zeros are always included for the hours and minutes. If the hour of
arrival is not available, "hh" shall be set to 24. If the minute of arrival
is not available, "mm" shall be set to 60. A null field indicates that this
is unchanged.
NOTE 6 The day and month of arrival are in UTC. The day is a two-digit fixed
number requiring leading zeros. The month is a two-digit fixed
number requiring leading zeros. If the day of arrival is not available,
"00" shall be the number for day. If the month of arrival is not
available, "00" shall be the number for the month. A null field
indicates that this is unchanged.
NOTE 7 The Navigational status is indicated using the following values, a null
field indicates the status is unchanged (ref. ITU-R M.1371, Message
1, Navigational status parameter):
0 = under way using engine
1 = at anchor
2 = not under command
3 = restricted manoeuvrability
4 = constrained by draught
5 = moored
6 = aground
7 = engaged in fishing
8 = under way sailing
9 = reserved for High Speed Craft
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
70
10 = reserved for Wing In Ground
11 to 14 = reserved for future use
15 = not defined (default)
NOTE 8 Definition of values 1 to 15 provided by a competent regional
authority. Value shall be set to zero (0), if not used for any regional
application. Regional applications shall not use zero. A null field
indicates that this is unchanged (ref. ITU-R M.1371, Message 1,
Reserved for regional applications parameter).
6.6 IEC 61162-1, Ed. 2, sentences
ACK – Acknowledge alarm
Acknowledge device alarm. This sentence is used to acknowledge an
alarm condition reported by a device.
ALR – Set alarm state
Local alarm condition and status. This sentence is used to report an
alarm condition on a device and its current state of acknowledgement.
DTM - Datum reference
Local geodetic datum and datum offsets from a reference datum. This
sentence is used to define the datum to which a position location, and
geographic locations in subsequent sentences, are referenced.
Latitude, longitude and altitude offsets from the reference datum, and
the selection of the reference datum, are also provided.
Cautionary notes: The datum sentence should be transmitted
immediately prior to every positional sentence (e.g. GLL, BWC, WPL)
which is referenced to a datum other than WGS84, the datum
recommended by IMO.
For all datums the DTM sentence should be transmitted prior to any
datum change and periodically at intervals of not greater than 30 s.
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
71
NOTE 1 Three character alpha code for local datum. If not one of the listed
earth-centred datums, or 999 for user defined datums, use IHO datum
code from International Hydrographic Organisation Publication S-60,
Appendices B and C. Null field if unknown.
NOTE 2 One character subdivision datum code when available or user defined
reference character for user defined datums, null field otherwise.
Subdivision character from IHO Publication S-60, Appendices B and
C.
NOTE 3 Latitude and longitude offsets are positive numbers, the altitude offset
may be negative. Offsets change with position: position in the local
datum is offset from the position in the reference datum in the
directions indicated:
Plocal datum = Pref datum + offset
NOTE 4 Users should be aware that chart transformations based on IHO S60
parameters may result in significant positional errors when applied to
chart data.
Only the local datum is required and used by the AIS.

GBS – GNSS satellite fault detection
This message is used for setting the RAIM flag in the position reports
sent by the AIS.
NOTE 1 Expected error in metres due to bias, with noise = 0.
NOTE 2 Satellite ID numbers. To avoid possible confusion caused by
repetition of satellite ID numbers when using multiple satellite
systems, the following convention has been adopted:
a) GPS satellites are identified by their PRN numbers, which range
from 1 to 32.
b) The WAAS system has reserved numbers 33 – 64 to identify its
satellites.
c) The numbers 65 – 96 are reserved for GLONASS satellites.
GLONASS satellites are identified by 64+ satellite slot numbers.
The slot numbers are 1 through 24 for the full GLONASS
constellation of 24 satellites, thus giving a range of 65 through 88.
The numbers 89 through 96 are available if slot numbers above 24
are allocated to on-orbit spares.
Only Expected error in latitude and Expected error in longitude is
required and used by the AIS.
GGA – Global positioning system (GPS) fix data
Time, position and fix-related data for a GPS receiver.
NOTE 1 GPS quality indicator:
0 = fix not available or invalid
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
73
1 = GPS SPS mode, fix valid
2 = differential GPS, SPS mode, fix valid
3 = GPS PPS mode, fix valid
4 = Real Time Kinematic. Satellite system used in RTK mode with
fixed integers
5 = Float RTK. Satellite system used in RTK mode with floating
integers
6 = Estimated (dead reckoning) mode
7 = Manual input mode
8 = Simulator mode
The GPS Quality Indicator shall not be a null field.
NOTE 2 Time in seconds since last SC104 type 1 or 9 update, null field when
DGPS is not used.
NOTE 3 Geoidal separation: the difference between the WGS-84 earth
ellipsoid surface and mean sea level (geoid) surface, " – " = mean sea
level surface below the WGS-84 ellipsoid surface.
Utc of position, Latitude, Longitude and GPS quality is the only fields
that are used by the AIS.
GLL – Geographic position – latitude/longitude
Latitude and longitude of vessel position, time of position fix and
status.
NOTE 1 Positioning system Mode indicator:
A = Autonomous
D = Differential
E = Estimated (dead reckoning)
M = Manual input
S = Simulator
N = Data not valid
NOTE 2 The Mode Indicator field supplements the Status field (field 6). The
Status field shall be set to V = invalid for all values of Operating
Mode except for A = Autonomous and D = Differential. The
positioning system Mode indicator and Status fields shall not be null
fields.
All fields are used by the AIS.

GNS – GNSS fix data
Fix data for single or combined satellite navigation systems (GNSS).
This sentence provides fix data for GPS, GLONASS, possible future
satellite systems and systems combining these. This sentence could be
used with the talker identification of GP for GPS, GL for GLONASS,
GN for GNSS combined systems, as well as future identifiers. Some
fields may be null fields for certain applications, as described below.
If a GNSS receiver is capable simultaneously of producing a position
using combined satellite systems, as well as a position using only one
of the satellite systems, then separate $GPGNS, $GLGNS, etc.
messages may be used to report the data calculated from the
individual systems.
If a GNSS receiver is set up to use more than one satellite system, but
for some reason one or more of the systems are not available, then it
may continue to report the positions using $GNGNS, and use the
mode indicator to show which satellite systems are being used.
NOTE 1 Mode Indicator. A variable length valid character field type with the
first two characters currently defined. The first character indicates the
use of GPS satellites, the second character indicates the use of
GLONASS satellites. If another satellite system is added to the
standard, the mode indicator will be extended to three characters; new
satellite systems shall always be added to the right, so the order of
characters in the Mode Indicator is: GPS, GLONASS, other satellite
systems.
The characters shall take one of the following values:
N = No fix. Satellite system not used in position fix, or fix not valid.
A = Autonomous.Satellite system used in non-differential mode in
position fix.
D = Differential. Satellite system used in differential mode in position
fix.
Seatex AIS 100 Instruction Manual, rev. 5 External interfaces
75
P = Precise. Satellite system used in precision mode. Precision mode
is defined as: no deliberate degradation (such as Selective
Availability), and higher resolution code (P-code) is used to compute
position fix.
R = Real Time Kinematic. Satellite system used in RTK mode with
fixed integers.
F = Float RTK. Satellite system used in real time kinematic mode with
floating integers.
E = Estimated (dead reckoning) Mode.
M = Manual Input Mode.
S = Simulator Mode.
The Mode indicator shall not be a null field.
NOTE 2 Age of differential data and Differential reference station ID
a) When the talker is GN and more than one of the satellite systems
are used in differential mode, then the "Age of differential data"
and "Differential reference station ID" fields shall be null. In this
case, the "Age of differential data" and "Differential reference
station ID" fields shall be provided in following GNS messages
with talker IDs of GP,GL, etc. These following GNS messages
shall have the latitude, N/S, longitude, E/W, altitude, geoidal
separation, mode and HDOP fields null. This indicates to the
listener that the field is supporting a previous $GNGNS message
with the same time tag. The "Number of satellites" field may be
used in these following messages to denote the number of
satellites used from that satellite system.
Example: A combined GPS/GLONASS receiver using only GPS differential
corrections has the following GNS sentence sent:
$GNGNS,122310.2,3722.425671,N,12258.856215,W,DA,14,0.9,1005
.543,6.5,5.2,23*59<CR><LF>
Example: A combined GPS/GLONASS receiver using both GPS differential
corrections and GLONASS differential corrections may have the
following three GNS sentences sent in a group:
$GNGNS,122310.2,3722.425671,N,12258.856215,W,DD,14,0.9,1005

For GPS differential data: This value is the average of the most
recent differential corrections in use. When only RTCM SC104 Type
1 corrections are used, the age is that of the most recent Type 1
correction. When RTCM SC104 Type 9 corrections are used solely, or
in combination with Type 1 corrections, the age is the average of the
most recent corrections for the satellites used. Null field when
Differential GPS is not used.
For GLONASS differential data: This value is the average age of
the most recent differential corrections in use. When only RTCM
SC104 Type 31 corrections are used, the age is that of the most recent
Type 31 correction. When RTCM SC104 Type 34 corrections are
used solely, or in combination with Type 31 corrections, the age is the
average of the most recent corrections for the satellites used. Null field
when differential GLONASS is not used.

8 MAINTENANCE
8.1 General
The Seatex AIS 100 consists of both software and hardware. The
software part can be reinstalled or upgraded to the latest version in the
field by running a software installation procedure. Service of the
Seatex AIS 100 hardware in the field can consist of:
• Exchange of damaged GPS or VHF antenna cables.
• Exchange of failed GPS or VHF antennas.
• Exchange of failed Seatex AIS 100 mobile station .
The Seatex AIS 100 requires a skilled technician to maintain most of
the hardware service.
8.2 Periodic maintenance
The AIS 100 should regularly be checked for firm and fixed mounting
of the chassis in order to avoid vibration and shock. All connectors
should be checked for good mechanical and electrical connections.
Cables should not be bent more than the minimum recommended
bending radius and there should be no sharp bends on coaxial cables.
All cables should be fixed tight and rigid to their supporting structure
(bulkhead, mast etc.) and special care should be taken where cables
run through holes with sharp edges.
A properly operating unit will show when it is transmitting and
receiving messages by short blinks on the TX and MSG LEDs.
Inspecting the LEDs for normal operation gives a good indication of
the operating status. In particular, there should be no red LEDs,
because red indicates alarms or severe faults. Any red LED indication
means that further investigation and servicing is necessary.
8.3 Repairs and modifications
Repair of the Seatex AIS 100 consists of exchange of damaged
antenna cables, exchange of GPS or VHF antenna and replacement of
the Seatex AIS 100 mobile station, connection box or MKD. Any
skilled electrician should be able to do this.
Seatex AIS 100 Instruction Manual, rev. 5 Maintenance

9 TROUBLESHOOTING
If the initialisation process fails, the alarm LED will turn red. Mobile
station failure can be divided into two categories:
• Hardware problems
• External interface problems
9.1 Hardware problems
Hardware problems can be divided into the following categories:
• Power supply failing
• GPS receiver failing
• VHF transceiver failing
• GPS and VHF antennas and cables
• Interface cables
9.1.1 Power supply failing
If the lamp PWR on the front of the mobile station does not light
green, the unit does not receive power. First check the fuse in the
connection box. If the fuse is OK, check that external power has been
connected to terminal screws 37 to 40 in the AIS 100 connection box
as stated in section 5.4 and that the supplied power is in accordance
with technical power specifications, section 4.3. If the transponder
outputs an alarm, the alarm condition can be read from the display.
9.1.2 GPS and VHF antenna cable connections
Typical problems when no GPS signal is received is that the GPS
antenna cable and/or connectors are damaged as well as loose or that
the cables are not properly connected. In order to check for antenna
cable problems, ensure that the GPS antenna is disconnected. The
Ohm reading between the centre and the shelf should be infinite if
there is no short-circuit in the cable. Make a short-circuit in the
opposite end of the cable and measure the resistance. Now the reading
should be approximately 0 Ohm.
9.1.3 GPS and VHF antenna malfunction
Disconnect the GPS antenna cable at the rear side of the mobile
station. Measure the resistance between the centre pin and shield in
the cable (with the antenna connected). The GPS antenna does not
have a defined resistance that can be measured. Therefore, before
measurements can be carried out, the antenna end of the cable needs
Seatex AIS 100 Instruction Manual, rev. 5 Troubleshooting
94
to be short-circuited. Measure between centre conductor and shield.
Resistance should be close to 0 Ohm.
Note! Switch off the power before disconnecting the antenna.
9.1.4 GPS receiver failing
If the mobile station does not compute position data and the GPS lamp
on the front of the mobile station does not light green, the GPS PPS
pulse is not being received and the GPS receiver inside the mobile
station should be checked. Disconnect the antenna cable at the rear
side of the hardware unit. The voltage output on the GPS antenna
connector should be approximately 4.8 – 5.0 V and indicates that the
GPS receiver supplies voltage to the antenna. If not, this indicates
problems with the GPS receiver. Disconnect and connect power (a
few times) and see if the mobile station starts up as normal. If not,
consult Seatex for advice.
9.1.5 VHF transceiver failing
If the VHF antenna and antenna cabling is OK and the MSG lamp on
the front of the mobile station does not light green and amber vice
versa, this indicates incorrect data reception on AIS channel 1 and 2.
Disconnect and connect power (a few times) and see if the mobile
station starts up as expected. If not, consult Seatex for advice.
9.2 External data interface problems
External data connections may be incorrect:
• Data input from main GPS source
• Heading from vessel heading sensor
9.2.1 Data input from main GPS/GNSS source
Position data output from the AIS mobile station is generated from the
vessel main GPS/GNSS receiver and received into the AIS unit using
serial line communication. If data is missing into the AIS mobile
station, the following steps should be taken in order to check for
missing position data:
• Check that cable connections are correctly terminated in the
connection box (terminal screws 19 to 27).
• If properly connected, check the serial line communication (baud
rate, parity, number of bytes transmitted, number of stop bits)
Seatex AIS 100 Instruction Manual, rev. 5 Troubleshooting
95
between transmitting (vessel GPS/GNSS receiver) and receiving
(parameters to be checked from the MKD unit) end.
• If OK, check that the position output format from the GPS/GNSS
receiver is in accordance with the expected input position format.
• If the mobile station still does not receive position data, consult
Seatex for advice.
9.2.2 Heading from vessel heading sensor
Heading data is received from the vessel gyro or magnetic compass. If
input data is missing, the following steps should be taken in order to
check for missing heading data:
• Check that cable connections are correctly terminated in the
connection box (terminal screws 19 to 27).
• If correctly connected, check the serial line communication (baud
rate, parity, number of bytes transmitted, number of stop bits)
between transmitting (vessel heading sensor) and receiving
(parameters to be checked from the MKD unit) end.
• If OK, check that the heading output format from the compass is
in accordance with the expected input heading format.
• If the mobile station still does not receive heading data, consult
Seatex for advice.
If the mobile station fails to operate properly, remove power by
removing the + 24 V power supply cable and then reapply power. The
mobile station should now initialise from start.
