Automatic Identification System

GENERAL

This product and related documentation must be reviewed for familiarization with safety

markings and instructions before operation.

This board was constructed in an ESD (electro–static discharge) protected environment. This is

because most of the semiconductor devices used in this board are susceptible to damage by static

discharge.

Depending on the magnitude of the charge, device substrates can be punctured or destroyed by

contact or mere proximity of a static charge. The results can cause degradation of device perfor-

mance, early failure, or immediate destruction.

These charges are generated in numerous ways such as simple contact, separation of materials,

and normal motions of persons working with static sensitive devices.

When handling or servicing equipment containing static sensitive devices, adequate precautions

must be taken to prevent device damage or destruction.

Only those who are thoroughly familiar with industry accepted techniques for handling static sen-

sitive devices should attempt to service circuitry with these devices.

In all instances, measures must be taken to prevent static charge build–up on work surfaces and

persons handling the devices.

ProTec AIS Introduction

1.1. General

The L--3 ProTec is an Automatic Identification System transponder which is fully

compliant to the technical specifications defined by the IMO and outlined in ITU.R.M

1371--1. The transponder employs the latest radio frequency and SOTDMA and

DSC controller technology to provide a high performance, automated, and reliable

identification system for commercial mariners. The Transponder is a fully automated

system which ties into ship’s navigational instruments to provide automatic transmis-

sion of ships identity, status, and maneuvering intentions via standard marine VHF

communication techniques. Sequencing of transmission between all vessels within

VHF range is provided through SOTDMA controlling software to handle high traffic

volume situations.

The Transponder is a fully automated system. This means that once it is installed

and turned on, no maintenance is required to keep it operational. The only time the

user needs to perform any function on the transponder is to change the ship’s Ves-

sel/Voyage data as required.

1.1.1. System Overview

The L--3 ProTec is an Automatic Identification System fully compliant with the IMO

specifications defined in IMO MSC.74(69) Annex 3, IEC 61993--2, and ITU.R

M.1371--1. This AIS transponder has been developed using technology applied in

the design of our VHF DSC Class A radio, a design which has been field tested for

over a decade with over 10000 units operational in the field. With the addition of the

SOTDMA controllers, the L--3 ProTec provides a cost--effective AIS solution which

will meet the needs of any vessel required to carry AIS. The compact, single--box

design allows the L--3 ProTec to be easily incorporated into any bridge layout thus

simplifying installation and cabling requirements.

The L--3 ProTec has been designed as maintenance-free unit which makes exten-

sive use of surface mount technology (SMT). The repair of printed wiring assemblies

(PWAs) containing SMT components requires specialized factory equipment, train-

ing, and techniques, therefore, such PWAs are not field-repairable.

As a result, maintenance philosophy for the L--3 ProTec is replacement of failed as-

semblies. In the case of the L--3 ProTec, the replaceable assemblies are the RF

Main PWA (205M0023--00), the Channel 70 PWA (205M0003--01), the Computer

PWA (p/n: 205M0272--00), the Display PWA (205M0051--00), the IEC PWA

(205M0274--00), and the Controller PWA (205M0008--00).

When it has been determined that one or more of these assemblies is faulty, the

faulty assembly(ies) should be removed and returned to the Aviation Recorders fac-

tory for repair or replacement. Attempts to repair any of these assemblies will void

the warranty. Extreme care should be used when handling these assemblies.

1.3. AIS Description

1.3.1. Compact Design

The completely self--contained L--3 ProTec is the most compact AIS unit available on

the market today with outside dimensions of 6.5” W (16.5 cm) x 3.4” H (8.6 cm) x

7.4” D (18.8 cm). It is easily mounted on any surface using either a trunion bracket

or flush--mount bracket. The data port on the faceplate provides for easy connection

to any external display in either mounting configuration.

1.3.2. Integral Minimum Keyboard Display (MKD)

In line with the compact design, the L--3 ProTec is a single--box design incorporating

an integral MKD which is fully IMO compliant. The interface includes a of 2.58” L (6.5

cm) x 1.16” H (2.9 cm) (160 x 64 Dots) backlit LCD screen for displaying alphanu-

meric text and a multifunction keypad. The closest three vessels within AIS range

will be displayed with each vessel identified by MMSI and ship name and will display

both range and bearing to each vessel.

The interface has been designed to facilitate data entry and retrieval with a minimum

of keystrokes. It also includes a Pilot port designed to allow any user to quickly and

easily attach a portable AIS--compatible display system directly to the AIS trans-

ponder for display of the AIS data. This display system can consist of any system

which recognizes the NMEA AIS string whether it’s installed on a handheld PC, lap-

top PC, or dedicated display.

1.3.3. Integral GPS

The L--3 ProTec includes an internal GPS receiver card. The internal GPS provides

timing data required for synchronization of transmission. By specifications, ship posi-

tional information in NMEA format is to be fed to the transponder from the ships ex-

ternal electronic position indicating system through the supplied data cable. The in-

ternal GPS requires a dedicated GPS antenna to be mounted on the superstructure

and the appropriate connections are supplied on the transponder unit back panel.

1.3.4. Data Interface

Each transponder will be delivered with an IEC--specified NMEA standard data cable

required to interface to ship’s sensors and external display. The description of this

interface cable is given in the Installation Section of this manual. The standard kit

includes an eight (8) ft. (2.5 meters) cable and a terminal block to facilitate the final

linkup to the ship’s navigational instruments.

1.3.6. Operational Modes

The ProTec AIS is designed to operate in each of three modes: Autonomous and

Continuous, Assigned and Polled which are defined below.

1.3.6.1 Autonomous and Continuous

This is the default mode. The ProTec AIS will determine its own schedule for trans-

mission of position and identification and will automatically resolve scheduling con-

flicts with other stations using the Self Organized Time Division Multiple Access

(SOTDMA) methodology.

1.3.6.2 Assigned

The ProTec will automatically switch to assigned mode when it is commanded by a

competent authority, such as a base or repeater station, to transmit on a specific

transmission schedule. In this mode, the ProTec allocates the defined slots and be-

gins transmitting on these slots. It will continue to transmit in these slots with a zero

slot time--out and a zero slot offset, until those slots have been removed from the

transmission schedule. The assigned slots use the SOTDMA access scheme, with

the time--out value set to the assigned slot time--out. The assignment terminates

when the slot time--out reaches zero of any assigned slot, and the ProTec returns to

autonomous and continuous mode.

1.3.6.3 Polled

The ProTec AIS will transmit a response to DSC interrogation messages from a ship

or competent authority and respond back on the same channel without interfering

with either of the other two modes. When an automatic response is required, trans-

mitted responses will be made on channel 70 unless the unit is instructed to transmit

on another channel. The ProTec is inhibited from transmitting on the AIS 1 and AIS

2 channels. If and when frequency channels other than channel 70 are used for

DSC transmissions, the receive capability of TDMA operations should not be

impaired more than it would be if all DSC messages were transmitted on channel

70.

1.3.6.4 Initialization

The ProTec AIS will enter into an Initialization mode at Power--Up during which it will

monitor the TDMA channels for one minute. During this initialization period, a dy-

namic directory of all users in the system will be created which includes user ID’s,

slot assignments, positions, and other transmitted data. After this initialization period

of 1 minute, the ProTec will enter the required operational mode and begin transmis-

sion of the AIS data on the required schedule.

Marine Systems

Aviation Recorders

Rev. 02 Page 1--11

July 29/03

Automatic Identification System

1.3.7. DSC Functionality

The Assigned and Polled operational modes are activated through a DSC message

transmitted by the competent authority. In order to provide for this, the ProTec AIS

contains a dedicated DSC receiver that is tuned to channel 70. DSC messages

originating from shore stations of competent authorities will define regional AIS fre-

quencies, regions of coverage, required transmission schedule and/or interrogation

request. The ProTec AIS will respond back to such DSC interrogations on the fre-

quency specified in a manner such that it does not interfere with the TDMA transmis-

sions by interleaving the transmission between TDMA transmissions. The DSC re-

sponse will be made after a random delay of 0 -- 20 secs provided the signaling

channel is clear and the TDMA transmissions are not interrupted.

1.3.8. AIS Broadcast Parameters

A Class A AIS unit broadcasts the following information every 2 to 10 seconds while

1.3.9. AIS Frequencies

The International Telecommunications Union World Radio Conference in 1997 desig-

nated two VHF radio frequencies: 161.975 MHz (AIS1, or channel 87B) and 162.025

MHz (AIS2, or channel 88B) for AIS. In the US, the first channel is owned by Mari-

TEL, a public coast station operator, and the second by the federal government. The

USCG signed a Memorandum of Agreement with MariTEL for use of AIS 1, and has

authority from the National Telecommunications and Information Administration to

use both AIS1 and AIS 2 US--wide for AIS operation. The USCG has asked the Fed-

eral Communications Commission to authorize any US vessel to operate AIS on

these two channels under its existing ship station license. The FCC released a No-

tice authorizing operation of AIS under a ship’s existing station license.

The Pilot input/output port is a part of the AIS Class A stations. If the installation of

the AIS equipment is such that a pilot cannot connect his Personal Pilot Unit (PPU)

with a reasonable length of cable, an extension cable must be installed with a con-

nector located on the bridge such that the PPU can be connected on the normal

working position of the port.

ProTec AIS Operation

2.1. Operation

The L--3 ProTec has been designed to require minimal user interaction during nor-

mal operation. The interface consists of an integral alphanumeric display with alpha-

numeric keypad providing for data entry, retrieval and display.

2.1.1. Minimum Keyboard Display

The L--3 ProTec includes and integral MKD which is fully IMO compliant. It is recom-

ended that the MKD should not act as the primary display due to limitations in

data presentation options. It should be used for configuration of the hardware and

entry of vessel and voyage specific data, which is required infrequently. It may also

serve as a backup display if the external display were to malfunction. L--3 strongly

recommends that the AIS Target Display Software (TDS) be used as the primary AIS

display system and this software is available from the hardware supplier. TDS is a

basic yet powerful graphic display software compatible with Windowstwhich pro-

vides numerous display options for the AIS data. Contact L--3 Communications for

further information and acquisition. The front face of the L--3 ProTec contains the fol-

lowing controls.

2.1.1.1 Power/Dim Control

A single control knob controls both the on/off function and backlighting level for the

LCD. To turn the unit ’On’, rotate the knob clockwise. To turn unit ’Off’ rotate counter-

clockwise fully. The degree of rotation determines the brightness of the LCD back-

light and rotation to the right will dim the backlighting.

2.1.1.2 Liquid Crystal Display

The display is an alphanumeric LCD with backlighting which will display data entry

forms and AIS target data for the nearest three vessels.

2.1.1.3 Key Pad

The keypad contains dedicated function buttons and alphanumeric buttons which

allow for data entry and retrieval.

2.1.1.4 Pilot Port

The Pilot Port is an IEC high speed (38400 kbs) data port which can be used to con-

nect any external display such as an ECS, or other PC--based software package.

2.1.2. Keypad Description

The keypad allows the user to access the menu system built into the transponder

interface. The keys are defined below:

NAV AIS Target Data Display

Pressing this button will bring the user to the main default screen which

will display the AIS target data for the nearest three vessels, or allows the

user to switch back to the “Own Ship” display if the nearest three vessels

are already displayed.

ENT Enter Key

Allows user to enter Edit mode, or to save data if already performing an

Edit operation.

CLR Clear Key

Used to clear data from a data entry field before entering new data .

Pressing once will clear the entire field.

Directional ARROW Keys

Used to navigate between data entry fields on a data entry form and scroll

right/left and up/down in an alphanumeric display field. When in Closest

toggle between the Ship Name display and the MMSI screen. (The MMSI

screen will always be displayed for a vessel if the ship name is not known.

FNC Function Key

Used as the initial key in a key sequence to access the various secondary

functions of the interface.

CAN Cancel Key

Used to cancel any edit made in a data entry field and revert data back to

preexisting data.

MSG Message Key

Used to access the text messaging window, in order to send Safety Text

Messages.

ESC Escape Key

Will bring user up one level on the menu system.

The blue text above some identify the secondary definitions for each button. These

secondary definitions are activated by pressing of the FNC button in a key se-

quence.

SETUP Enters the system configuration menu system.

HOME Returns cursor to start position in a data entry field

END Returns cursor to end position in a data entry field

ALL Will clear all contents of a data entry field when preceded by the FNC key.

The alphanumeric keypad is used to enter both numbers and letters. When alphanu-

meric text entry is expected, the nonnumeric options are presented before the nu-

meric value of the key. For example, the number “2” key provides for entry of “A”,

“B”, and “C”. When the cursor is positioned in a display field location that expects an

alphanumeric character, the first press of the “2” key will result in the display of an

“A”. Another press (in a fairly short time) will cause a “B” to be displayed. The next

press shows a “C”, while the forth press shows a “2”.

Repeated key presses will result in cycling through the character options repeatedly.

When the operator stops pressing keys for longer than the preset timeout, the last

value is retained and the cursor moves to the next location in the field. Pressing a

different key forces acceptance of the last character for the field and moves the cur-

sor along.

3.1.1. Transponder

The L--3 ProTec is a single box design which is easily installed into any existing

bridge layout. The compact design requires minimal clearance (refer to Figure 3--2

and Figure 3--3) and can be mounted in a trunion bracket or mounted flush using the

available flush--mount bracket. Install the transponder is as follows:

(1) Mount the transponder in a position which provides easy access to the key-

board and display. If using the trunion bracket, the mount itself may be used to

mark the screw holes on the mounting surface. When locating the transponder,

consider that the IMO mandates that the AIS keyboard and display be easily

accessed from a navigable position on the bridge.

(2) If used, Mount the transponder in the trunion utilizing the trunion knobs pro-

vided, otherwise mount transponder in flush mount bracket.

(3) Locate and mount the terminal block or junction box in a position near the

transponder. The IEC cable provided with the unit is 100 inches (2.5 m) long

and the terminal block should be located to take this into account. Locate the

terminal block in a fashion which allows for easy access to the terminals for

making the connections to required input/output feeds.

(4) Refer to Figure 3--4. Connect the transponder power cable to the power con-

nection on the Transponder and connect to the ships 12--24 Vdc power supply.

The “Red“ lead goes to positive and “Black“ to negative. Ensure proper ground

wire attachment to ships structure.

The other two leads can be used to connect to an external alarm system. This

alarm system can provide an audio and/or visual alarm in the event of an inter-

nal system malfunction, or if the AIS loses power or is turned off.

For steps (5) through (7) refer to Paragraph 3.1.2.

(5) Connect the IEC cable to data port on back of Transponder using J4 connector

provided.

(6) Lead data cables from Gyrocompass data output port and ship’s DGPS data

output port. To terminal block. If an interface adapter must be used to convert

either Gyro output and/or dGPS output to IEC (NMEA 0183) standard, the out-

put from the interfaces should be located as near as possible to the sending

unit (Gyro or dGPS) and the output cables led to the IEC terminal block.

(7) Feed the IEC data cable pigtail to the terminal block.

(8) Do not power up the unit at this time. The transponder should not be powered

up without the VHF antenna connected.

(9) If an external display system is to be connected for display of the AIS target

data, lead the cable from the display unit to the terminal block. (Refer to

Figure 3--5.)

3.1.2. Connecting the IEC Data Interface Cable

The AIS Transponder receives data from the ship’s sensors through a data interface

cable which is connected to the back of the transponder through a data port. IMO

regulations require that the ship heading, speed--over--ground (SOG), course--over--

ground (COG), rate--of--turn (ROT) and position be transmitted from the AIS. In or-

der to meet these requirements, the L--3 ProTec provides six (6) data channels to

allow the AIS to be connected to the ships Gyrocompass and DGPS system in ac-

cordance with NMEA 0183.

The L3 AIS is shipped with one IEC interface cable P/N 024--M0088--01. All IEC/Pi-

lot communications with the AIS is referenced with the L--3 ProTec considered the

“MASTER” in that transmit data is OUTPUT from the L--3 ProTec, and receive data is

INPUT to the L--3 ProTec. All channels are isolated with individual shielded twisted

pair cables. Refer to Figure 3--7. The IEC connector (J4) is located on the back of

the L--3 ProTec. (Refer to IEC 61993--2 annex D. and NMEA 0183) IEC channels 1,

2, and 3 are RECEIVE ONLY sensor inputs. Differential data (RS422) is received on

each of these channels and internally converted to TTL for input to a standard

UART. Channels 4, 5, and 8 are all RS422 interfaces. IEC channels 4 and 5 are

TRANSMIT/RECEIVE channels for AIS data. IEC channel 8 is the AIS long range

port.

3.1.2.1 Data Channels

Data enters the Transponder through six (6) available data channels. Three data

channels are low speed unidirectional (4800 baud) channels suitable for data input

to the transponder. The other three data channels are high speed bidirectional

channels (38400 baud) which support both input and output to/from the transponder.

The channels are described below by channel number and type. Suggested uses of

each channel are provided but it is not required that a user define the channels in

this fashion. The internal software in the transponder is able to distinguish the type

of data feeding from each channel provided all data streams subscribe to the IEC

61162 format (NMEA 0183).

3.1.2.2 Data Cable

Each transponder will come shipped with an 100 inches long IEC data cable (P/N

024--M0088--01) terminated at one end by a J4 connector. (Refer to Figure 3--6,

Figure 3--7 and Figure 3--8.) The IEC data cable is shielded and contains three

smaller diameter cables, each of which is also shielded. Each of these smaller

cables contains three shielded twisted pairs (STP) each and each STP includes a

drain wire. A low speed unidirectional (input only) data channel (4800 kbs) is carried

through one STP, and a high speed bidirectional (input/output) data channel (38400

kbs) will require two pairs.

3.1.2.3 Terminal Block

Each Transponder will come shipped with a 31 pin terminal block. A terminal block is

the preferred installation method for completing the data interface (NMEA) because

data output from a ship sensor ( dGPS, ROT, Gyro) may not subscribe to a standard

pinout definition. As such, each installation may require that the installer identify

and cross reference the sensor pinouts with the IEC pinouts, which is a well defined

standard pinout description. The terminal block allows for greater flexibility in com-

pleting the connection to the ship’s sensors.

A junction box may be made available which terminates the data cable on the termi-

nal block and provides serial connectors to allow for easy connection to ship sen-

sors. However, the installer will need to confirm the pinout definitions for the sensor

outputs before completing the connection correctly.

To complete the data connection to the ship’s sensors, perform the following:

(1) Connect the data cable to the back of the transponder unit.

(2) Feed the data cable into the console to the position in which the terminal block

will be placed.

(3) Locate an ideal position for the terminal block.

FProtected from weather.

FProtected from high heat.

FProtected from accidental contact with conductive material.

FWithin 100 inches (2.5 m) of the transponder due to IEC data cable length.

FGrounding of terminal block to ship’s structure.

FNeed to feed cables from navigational sensors.

(4) Mount the terminal block to the ships structure with self tapping screws

(5) Ground terminal block to ship’s structure using grounding cable provided.

(6) Connect each wire to the correct terminal block position. Use the table below

which gives the IEC pin ID (and color code) and identifies the correct terminal

block position ID.

NOTE: The metallic shielding of each of the three shielded cables

containing the twisted pairs must be connected to the ter-

minal block using the shield drain wire connected to the

shield. The shields from Cables 1 and 2 do not have to be

connected. The shield from Cable 3 must be connected to

TB pin ID 30, which is grounded to the ship’s hull.

3.1.3. Installing the VHF Antenna

Installation of a VHF antenna is as important to reliable communications as the

transceiver itself. It is recommended that a high quality antenna be purchased from

an established source and that all manufactures instructions be followed with partic-

ular attention to cable routing and connector installation. Some important consider-

ations in antenna installation are:

FIn general, antennas should be located as high as practical on the vessel

and separated as much as possible from each other.

FThe VHF antenna should be placed in an elevated position with a mini-

mum of 2 meters clearance from any construction that is made with con-

ductive material. In addition, it should not be installed close to any large

vertical obstruction, and the VHF antenna should have a 360°line of sight

to the horizon.

FIt is preferable that the VHF antenna is installed at least 3 meters away

from high power energy sources such as radar and other transmitting ra-

dio antennas, and out of the transmitting beam.

FThere should not be more than one antenna on the same level. The AIS

VHF antenna should be mounted directly above or below the ship’s prima-

ry VHF radiotelephone antenna, with no separation and with a minimum of

2 meters vertical separation. If the VHF antenna is located on the same

level as other antennas, the distance between them should be at least 10

meters.

To install the VHF antenna, perform the following:

(Refer to Figure 3--9 and Figure 3--10.)

(1) Position the antenna mounting bracket on a rigid and structurally sound sur-

face. In general, two bracket types are available, a rail mount and a flat (pad-

eye) mount. Some mounts have a ratchet mechanism which allows them to be

mounted on an inclined surface. Whichever mount is used; ensure the quality

of the mount. L--3 recommends a heavy gage stainless steel mount be used in

the mounting of the antenna.

(2) Install the antenna on the antenna mount.

(3) Run the coaxial cable from the antenna to the transponder location. Use only

high quality RG8X or RG214 coaxial cable and keep cable length as short as

possible to reduce signal attenuation.

(4) Trim cable to length leaving a few inches slack at the transponder.

(5) Attach the connectors to the end of the coaxial cable.

(6) Connect the cables to the transponder. Soldering the connection is not

required.

Aviation Recorders

Rev. 02 Page 3--16

July 29/03

Automatic Identification System

3.1.4. Installing the GPS Antenna

The correct installation of a GPS antenna is crucial to the operation of the trans-

ponder because the internal transmission synchronization relies on the accuracy of

the time signal obtained from the GPS. It is recommended that a high quality GPS

antenna be purchased from an established source and that all manufactures instruc-

tions be followed with particular attention to cable routing and connector installation.

Some important considerations in GPS antenna installation are:

FGPS antennas should be located to provide a clear, unobstructed view of

the sky.

FGPS signals can be affected by RADAR and SATCOM transmissions. As

such, GPS antennas should be positioned below and at least 5 meters

away from RADAR and SATCOM antennas and outside of the beam path.

FGPS signals can also be affected negatively by VHF and HF transmis-

sions, and the GPS antenna should be positioned at least 3 meters from

these types of antennas.

FThe GPS antennas can be flat mounted onto any surface but it is recom-

mended that it be elevated from the deck surface (20--30 cm) to prevent

ice or spray from negatively impacting the signal reception.

FRecently, it has been identified that certain makes/models of TV antennas

can drastically interfere with GPS reception. As such, the installer should

place the GPS antenna as far away from any shipboard TV antennas as

possible and confirm that any antennas used on board are not ones which

have been exhibited GPS interference problems.

To install the GPS antenna, perform the following:

(Refer to Figure 3--9 and Figure 3--10.)

(1) Position the antenna mounting bracket and/or antenna mast on a rigid and

structurally sound surface.

(2) Install the antenna on the antenna mount.

(3) Run the coaxial cable from the antenna to the transponder location through an

existing throughhull. Use only high quality RG59 coaxial cable and keep cable

length as short as possible to reduce signal attenuation.

(4) Trim cable to length leaving a few inches slack at the transponder.

(5) Attach the connectors to the end of the coaxial cable.

(6) Connect the cable to the transponder. Soldering the connection is not required.

(9) This completes the configuration requirements of the AIS. The next step involves

checking the system linkup to ship’s dGPS and Gyro. To check these links you

must enter the Own Ship Data screen of the interface.

(10) Enter FNC and then ENT. This will get you to Own Ship Data screen. The screen

will display ship positional and heading information.

(11) Confirm ship positional data, heading and SOG/COG/ROT data is correct by refer-

encing the equipment repeater display.

The AIS is now placed in service. It is to remain operational at all times when the

vessel is operating unless given specific authorization to discontinue operation by

local maritime authorities. The only interaction with the interface will be to view sur-

rounding ship traffic identification information and to enter voyage specific data at

the start of each voyage.
