Installation
2.4 Cabling
Double shielded coaxial cables equal or better than RG-214 are
recommended when connecting the GPS and VHF antennas to the
AI80 system.
Coaxial cables should be installed in separate signal cable
channels/tubes and at least 10 cm away from power supply cables.
All outdoor installed connectors on the coaxial cables should be fitted
with preventive isolation such as shrink-stocking with silicone to
protect against water penetration.
Avoid sharp bends of the cables. A bend may change the
characteristic impedance of the cable.

Installation
2.5 Location of the units
The units included in the AI80 system should be mounted with special
regard to the units’ environmental protection, temperature range and
cable length. Refer Technical specifications, page 1 onwards.
Antenna location
The AIS equipment, like any other ship borne transceiver operating in
the VHF maritime band, may cause interference to a ship’s VHF
radiotelephone. This interference may occur as a periodic (e.g. every
20 s) soft clicking sound on a ship’s radiotelephone.
This affect may become more noticeable when the VHF
radiotelephone antenna is located near the AIS VHF antenna, and
when the radiotelephone is operating on channels near the AIS
operating channels (e.g. channels 27, 28 and 86).
The figure below shows recommended location and distance between
the different antennas.
Man_inst_AI80_r1

Simrad AI80 Installation Manual
2.6 MKD unit
Mechanical installation
The MKD may be panel or bracket (option) mounted. The optional
mounting bracket may be ordered separately.
The unit should be mounted with special regard to the operator’s need
for easy operation.
Avoid mounting the MKD where it is easily exposed to sunlight, as
this will shorten the lifetime of the display. If this is not possible,
make sure the units are always covered with a protective cover when
not in use.
Panel mounting
Make sure that the mounting location includes space for plug and
cable bend.
The mounting surface must be flat and even to within 0.5 mm.

GPS antenna
Mechanical installation
The GPS antenna included in the AI80 system is used for time
synchronisation and computation of backup position fix. In addition to
this GPS antenna, the AI80 should be connected to the vessel’s main
GPS system at the rear of the Mobile Unit. Sensor input 1-3 may be
used.
Optimum location of the GPS antenna is important to ensure
continuous track of all visible GPS satellites. 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.
• The antenna should be located 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.
Refer figure on page 15.
Use the supplied antenna mounting kit when mounting the antenna.
Appropriate crimping tools must be used.
GPS antenna offset arms
22
The mounting location for the internal GPS antenna and for the
main GPS antenna connected to the AI80 system, needs to be
input to the AI80 as a part of the configuration settings. The
figure shows the offset arms that have to be configured.
Refer Entering static data, pages 32 and 90.
Man_inst_AI80_r1
Installation
Checking the antenna cable
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, the antenna cable could be connected to the Mobile
Unit.
Sealing antenna connectors
The outdoor antenna connectors have to be sealed with self-bounding
tape and PVC/Vinyl tape for waterproofing.
Coil the self-bounding tape from one cable end to the other. Use at
least two layers of tape. After coiling, make a bounding by pressure of
fingers.
Coil at least two layers of PVC/Vinyl tape without stretching. After
coiling, make a bounding by pressure of fingers.
2.12
VHF antenna
The VHF antenna is not included in a standard AI80 system, but has
to be part of the AIS installation. A qualified antenna must cover
marine band (156 MHz - 164 MHz), have omni-directional vertical
polarization and provide 2 to 5 dB gain.
For installation of this antenna, refer to documentation delivered by
the antenna supplier. Refer also to the figure on page 15 for location.
Verify that there is no short circuit between centre conductors and
shield (ground) before the cable is connected to the Mobile Unit. Seal
the antenna connectors as described for the GPS antenna.
As an option Kongsberg Seatex AS may provide an antenna with part
number A100-58, shown in Appendix E - Optional VHF antenna.

Maintenance
5 MAINTENANCE
5.1 General
All units in the AI80 system are “repair by replacement” units, and the
operator is therefore required to perform only a limited amount of
preventive maintenance on the units.
The service in the field is limited to:
• Replacing damaged GPS or VHF antenna cables
• Replacing failed AI80 system units
A damaged unit that has to be shipped back to the supplier, should be
sent in the original transportation box or another appropriate box. The
return address is provided in the first pages of this manual.
5.2 Periodic maintenance
The AI80 system should regularly be checked for firm and fixed
mounting of the chassis in order to avoid excessive resonances. 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.
MKD Units
The MKD will under normal use require little maintenance.
If the unit requires any form of cleaning, use fresh water and a mild
soap solution (not a detergent). It is important to avoid using chemical
cleaners and hydrocarbons such as diesel, petrol etc.
Mobile Unit
A properly operating Mobile Unit will indicate 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. Any red LED indication means that further
investigation and servicing is necessary, see chapter 6.1.
Man_inst_AI80_r1

Simrad AI80 Installation Manual
5.3 Repair and modifications
The units in the AI80 system are not designed for customer repair. All
repairs and modifications of the units should be carried out by
qualified personnel. A failed unit should be shipped back to the
supplier for repair.
Exchanging antenna cables
1. Disconnect the power cable.
2. Dismount the damaged antenna cable. The new antenna cable
must be as straight as possible. Do not crush or crimp the
cable, as this will affect the electrical properties of the cable.
3. Connect the antenna cable to the antenna.
4. Seale the connection between the antenna and the antenna
cable against water penetration as described in page 23.
5. Connect the antenna cable to the AI80 Mobile Unit and
reapply power.
Note !
If the GPS antenna cable is attached to the Mobile Unit, do not
attach the antenna cable to the antenna when the AI80 is powered.
If the antenna cable is short-circuited with power on, the GPS
receiver within the unit can be damaged.

Prior to any troubleshooting, the system should be restarted to see if
this resolves the problem.
• Restart the Mobile Unit as described in the Simrad AI80 User
Manual.
• Remove the + 24 V power supply cable and then reapply
power.
6.2 Hardware problems
Hardware problems can be divided into the following categories:
• Power supply failure
• GPS receiver failure
• VHF transceiver failure
• GPS and VHF antennas and cables
• Interface cables
Man_inst_AI80_r1
41
Simrad AI80 Installation Manual
If the system outputs an alarm, the alarm condition can be read from
the display.
Power supply failure
If the unit periodically restarts approximately every one minute, this
could indicate a power supply failure.
Use the following procedure to check for power failure:
1. Check that external power has been connected to the rear
connectors.
2. Verify that supplied power is in accordance with technical
power specifications, page 1.
3. Verify that power cable dimensions are minimum 2.5 mm2.
GPS and VHF antenna cable connections
Typical problems when no GPS signal is received are that the GPS
antenna cable and/or connectors are damaged, 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 screen should normally 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.
GPS and VHF antenna malfunction
Disconnect the GPS antenna cable at the rear side of the Mobile Unit.
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
to be short-circuited. Measure between centre conductor and shield.
Resistance should be close to 0 Ohm.
Caution!
Switch off the power before disconnecting the antenna!
GPS receiver failure
During normal operation the GPS LED blinks green once each
second. If the GPS LED on the front of the unit blinks amber, the
AI80 system computes no position data, the GPS receiver inside the
Mobile Unit should be checked.
42
Man_inst_AI80_r1
Troubleshooting
Disconnect the antenna cable at the rear side of the Mobile Unit. The
voltage output on the GPS antenna connector should be approximately
4.8 – 5.0 V if the GPS receiver supplies voltage to the antenna. If not,
this indicates problems with the GPS receiver. Disconnect and
reconnect power to see if the Mobile Unit starts up as normal. If not,
consult Customer Support for advice.
VHF transceiver failure
If there is no activity on the TX and/or the MSG LED on the front of
the unit, this indicates a transmitter or receiver problem. Disconnect
and reconnect power to see if the Mobile Unit starts up as expected. If
not, consult Customer Support for advice.
6.3 External data interface problems
External data connections may have incorrect:
• Data input from main GPS source
• Data input from vessel heading sensor
Check NMEA version, see table on page 29.
Data input from main GPS/GNSS source
Position data input to the AI80 system is received from the vessel’s
main GPS/GNSS receiver using an RS-422 serial line communication.
If data are not received in the AI80 Mobile Unit, the following steps
should be taken in order to check for missing position data:
1. Check that corresponding cable connections are correctly
terminated, refer chapter 3.4 and note on page 20.
2. If properly connected, check the serial line communication
(baud rate, parity, number of bytes transmitted, number of stop
bits) between transmitting (vessel GPS/GNSS receiver) and
receiving (parameters to be checked from display) end.
3. If OK, check that the position output format from the
GPS/GNSS receiver is in accordance with the expected input

Heading from vessel heading sensor
Heading data is received from the vessel’s gyro. If input data is
missing, the following steps should be taken in order to check for
missing heading data:
1. Check that corresponding cable connections are correctly
terminated, refer chapter 3.4 and note on page 20.
2. 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.
3. If OK, check that the heading output format from the compass
is in accordance with the expected input heading format, see
page 28 and Appendix B - Digital interface IEC 61162-1.
If the Mobile Unit still does not receive heading data, consult
Customer Support for advice.
AIS unit restarts
If the AIS unit frequently restarts, please note that the AIS is
dependent upon 24 V DC/50 W, see Power supply failure on page 42.
1. Check that external power source has sufficient current rating
(recommended 4 A) and that
2. power cables are within specifications for such a power
consumption.

Hardware
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 shown on figure on
page 20. 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.
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.

Proprietary 61162-1 sentences
General
In order to configure and service the AI80 Mobile Unit there are some
proprietary messages that can be used on the PI or Pilot interface. The
AIS Mobile Unit uses the NMEA registered "STX" manufacturer’s
code. When setting parameters in the AIS Mobile Unit use the
$PSTXS command. To query the AIS Mobile Unit for information,
use the $PSTXQ command. Responses from the AIS Mobile Unit
uses the $PSTXR command. The proprietary messages comply with
IEC 61162-1 and have the following structure:

Reference is made to IEC 61193-2, 2001, annex B2 and IEC/PAS 61162-100. 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 AIRsentence, 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 (ITUR M.1371 message 15), the MMSI of the first distant AIS unit, identified in the message, is the MMSI reported here. When the 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. Man_inst_AI80_r1 55 Simrad AI80 Installation Manual 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: NOTE 5 56 ITU-R M.1371 Message ID Message Sequence Number source sequential message identifier from ABM-sentence, IEC 61162-1 addressed AIS unit's message 7, sequence number, ITU-R M.1371 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 Acknowledgements provided are: = message (6 or 12) successfully received by the addressed AIS unit, = message (6 or 12) was broadcast, but no acknowledgement by the distant addressed AIS unit, = message could not be broadcast, = 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 acknowledgement process active for the acknowledgement that was received. Man_inst_AI80_r1 Appendix B - Digital Interface IEC 61162-1 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 ABKsentence with an acknowledgement of "2" – message could not be broadcast. NOTE 1 Man_inst_AI80_r1 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 identifies the order of this sentence in the message, minimum value 1. All sentences contain the same number of fields. Successive sentences 57 Simrad AI80 Installation Manual 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. 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. NOTE 6 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. 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 58 Man_inst_AI80_r1 Appendix B - Digital Interface IEC 61162-1 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 NOTE 4 Value of 0, bandwidth is specified by channel number, see ITU-R M.1084, Annex 4 Value of 1, bandwidth is 12,5 kHz. Man_inst_AI80_r1 59 Simrad AI80 Installation Manual NOTE 5 Value of 0, transmit on channels A and B, receive on channels A and 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: A, ITU-R M.1371 message 22: Channel Management addressed message, B, ITU-R M.1371 message 22: Channel Management broadcast geographical area message, 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. 60 Man_inst_AI80_r1 Appendix B - Digital Interface IEC 61162-1 The success or failure of the interrogation broadcast is determined by 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: Message 3, Position Report, Message 5, Ship Static and Voyage related data, Message 9, Standard SAR Aircraft Position Report, Message 18, Standard Class B Equipment Position Report, Message 19, Extended Class B Equipment Position Report, and Message 21, Aids-to-Navigation Report. 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 Man_inst_AI80_r1 This field is used to request a message that has been further subdivided into alternative data structures. When requesting messages 61 Simrad AI80 Installation Manual 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 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. 62 Man_inst_AI80_r1 Appendix B - Digital Interface IEC 61162-1 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 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 BBMsentence. (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 LRIsentence 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. Man_inst_AI80_r1 63 Simrad AI80 Installation Manual 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.) 64 Man_inst_AI80_r1 Appendix B - Digital Interface IEC 61162-1 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 Man_inst_AI80_r1 65 Simrad AI80 Installation Manual E = Course over ground F = Speed over ground I = Destination and Estimated Time of Arrival (ETA) 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. 66 Man_inst_AI80_r1 Appendix B - Digital Interface IEC 61162-1 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: 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. Man_inst_AI80_r1 67 Simrad AI80 Installation Manual 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. 68 Man_inst_AI80_r1 Appendix B - Digital Interface IEC 61162-1 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 Man_inst_AI80_r1 69 Simrad AI80 Installation Manual receiving applications that, if set to "available" the transmitting station conforms, at least, to the minimum keyboard and display 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 NOTE 2 70 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. 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 Man_inst_AI80_r1 Appendix B - Digital Interface IEC 61162-1 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. 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 Man_inst_AI80_r1 71 Simrad AI80 Installation Manual 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 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. 72 Man_inst_AI80_r1 Appendix B - Digital Interface IEC 61162-1 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. 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 Man_inst_AI80_r1 73 Simrad AI80 Installation Manual 4 = constrained by draught 5 = moored 6 = aground 7 = engaged in fishing 8 = under way sailing 9 = reserved for High Speed Craft 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). 74 Man_inst_AI80_r1 Appendix B - Digital Interface IEC 61162-1 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. Note ! 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. Man_inst_AI80_r1 75 Simrad AI80 Installation Manual 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. 76 Man_inst_AI80_r1 Appendix B - Digital Interface IEC 61162-1 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: GPS satellites are identified by their PRN numbers, which range from 1 to 32. The WAAS system has reserved numbers 33 – 64 to identify its satellites. 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 onorbit 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 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 Man_inst_AI80_r1 77 Simrad AI80 Installation Manual 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. 78 Man_inst_AI80_r1 Appendix B - Digital Interface IEC 61162-1 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. Man_inst_AI80_r1 79 Simrad AI80 Installation Manual D = Differential. Satellite system used in differential mode in position fix. 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 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 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 .543,6.5,,*74 $GPGNS,122310.2, , , , , , 7, , , ,5.2,23*4D $GLGNS,122310.2, , , , , , 7, , , ,3.0,23*55 The Differential Reference station ID may be the same or different for the different satellite systems 80 Man_inst_AI80_r1 Appendix B - Digital Interface IEC 61162-1 b) Age of Differential Data 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. NOTE 3 HDOP calculated using all the satellites (GPS, GLONASS and any future satellites) used in computing the solution reported in each GNS sentence. NOTE 4 Geoidal separation is the difference between the earth ellipsoid surface and mean-sea-level (geoid) surface defined by the reference datum used in the position solution, "-" = mean-sea-level surface below ellipsoid surface. The reference datum may be specified in the DTM sentence. UTC of position, Latitude, Longitude and Mode indicator, are the only fields used by the AIS. HDT – Heading true IMO Resolutions A.424 and A.821. Actual vessel heading in degrees true produced by any device or system producing true heading. All fields are used by the AIS. Man_inst_AI80_r1 81 Simrad AI80 Installation Manual OSD Own ship data IMO Resolution A.477 and MSC 64(67), Annex 1 and Annex 3. Heading, course, speed, set and drift summary. Useful for, but not limited to radar/ARPA applications. OSD gives the movement vector of the ship based on the sensors and parameters in use. NOTE Reference systems on which the calculation of vessel course and speed is based. The values of course and speed are derived directly from the referenced system and do not additionally include the effects of data in the set and drift fields. B = bottom tracking log M = manually entered W = water referenced R = radar tracking (of fixed target) P = positioning system ground reference. Heading, Heading status, Vessel course, Vessel speed and Speed units, are used by the AIS. RMC - Recommended minimum specific GNSS data Time, date, position, course and speed data provided by a GNSS navigation receiver. This sentence is transmitted at intervals not exceeding 2 s and is always accompanied by RMB when a destination waypoint is active. RMC and RMB are the recommended minimum data to be provided by a GNSS receiver.
