This section provides an overview of the AI70 Automatic
Identification System and its components.

Simrad AI70 Automatic Identification System
1.1 Introduction
AI70 is an Automatic Identification System (AIS) that uses VHF communication to transmit and receive AIS data. An AIS system 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 system 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 system is designed to operate automatically and as a stand-alone unit.
When not transmitting, the system listens for position information from other vessels or shore based stations.

SYSTEM OVERVIEW
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 a vessel’s AIS system 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

Simrad AI70 Automatic Identification System
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.
Ship's Manoeuvring Condition Nominal Reporting Interval
Ship at anchor
Ship 0 to 14 knots
Ship 0 to 14 knots and changing course
Ship 14 to 23 knots
Ship 14 to 23 knots and changing course
Ship > 23 knots
Ship > 23 knots and changing course

Note!
The MKD unit provides a simple user interface to the Mobile
Station. The unit provides basic presentation of configuration data and position data.
The buttons on the unit is used selecting display pages, for input of data to the system, and for writing text messages transmitted to other vessels or shore based AIS stations.
A Pilot Plug is included in the AI70 system. The plug makes it possible for the pilot to connect a Personal Pilot Unit (PPU) to the AIS system.
The Connection box is used for interfacing the AI70 system to external equipment.
Power is connected to the AI70 system via the Connection box.
The GPS antenna included in the AI70 system is an L1 antenna receiving signals from all visible satellites. The antenna is delivered with a universal antenna mounting kit and an adapter cable with “N” connectors for connection to a customer supplied low loss coax cable, e.g. RG-214.
This GPS antenna is used for time synchronisation and computation of backup position fix. In addition to this antenna, the AI70 should be connected to the vessel’s main GPS system via the AI70 Connection Box.
A customer supplied VHF antenna must be included in the AI70 system. This antenna must be omni-directional vertical polarization, providing 3 to 5 dB gain.

Simrad AI70 Automatic Identification System
3.1 General
Caution!
The AI70, once activated, will continuously and autonomously broadcast the vessel’s position and all the static and dynamic information as required by IMO.
However, while the vessel’s speed and rate of turn maneuvers will automatically determine the update rate, there remains a need for the Master or an authorized person to manually input, at the start of the voyage and whenever changes occur, the following voyage related data:
- ship’s draught
- type of hazardous cargo (most significant hazard carried)
- destination and ETA (at master’s discretion)
- the correct and actual navigational status
- short safety related short messages, when appropriate
Refer Changing parameters during operation, page 19 onwards.
The Officer on Watch (OOW) should always be aware that other ships and, in particular, leisure craft, fishing boats and warships, and some coastal shore stations including Vessel
Traffic Service (VTS) centers, might not be fitted with AIS.
The OOW should also be aware that AIS fitted on other ships as a mandatory carriage requirement, might, under certain circumstances, be switched off on the Master’s professional judgment.
An AIS system should always be in operation. It is recommended that the AIS is not switched off during port stays because of the value of the ship information to port authorities.
Whether at sea or in port, if the Master believes that the continued operation of AIS might compromise the ship’s safety or security, the VHF transmitting may be switched off as described in Turning the VHF Transmitter OFF, page 21. This might be the case in sea areas where pirates and armed robbers are known to operate.
However, the VHF transmitting should be re-activated as soon as the source of danger has disappeared.
It may be necessary to switch off AIS or to reduce the transmission power during some cargo handling operations.
Actions of this nature should always be recorded in the ship’s logbook.

5.5 Location of the Units
The units included in the AI70 system should be mounted with special regard to the units’ environmental protection, temperature range and cable length. Refer TECHNICAL
SPECIFICATIONS, page 33 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 20s) 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.

5.11 GPS Antenna
A
B
Mechanical installation
The GPS antenna included in the AI70 system is used for time synchronisation and computation of backup position fix. In addition to this GPS antenna, the AI70 should be connected to the vessel’s main GPS system via the AI70 Connection Box.
Optimum location of the GPS antenna is important to ensure continuously 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 meters 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 46.
Use the supplied antenna mounting kit when mounting the antenna.
GPS antenna offset arms
The mounting location for the internal GPS antenna and for the main GPS antenna connected to the AI70 system, needs to be input to the AI70 as a part of the configuration settings. The figure shows the offset arms that have to be configured.
Refer Entering static data, page 67.
C D
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 station.
53
Simrad AI70 Automatic Identification System
Sealing antenna connectors
The outdoor antenna connectors have to be sealed with selfbonding tape and PVC/Vinyl tape for waterproofing.
Coil the self-bounding tape from one cable end to the other. Use at least two layers with tape. After coiling, make a bonding by pressure of fingers.
Coil at least two layers of PVC/Vinyl tape without stretching.
After coiling, make a bonding by pressure of fingers.
5.12 VHF Antenna
The VHF antenna is not included in a standard AI70 system, but has to be part of the AIS installation. The antenna should be omni-directional vertical polarization, providing 3 to 5 dB gain.
For installation of this antenna, refer to documentation delivered by the antenna supplier. Refer also to the figure on page 46.
Verify that there is no short circuit between centre conductors and shield (ground) before the cable is connected to the Mobile station. Seal the antenna connectors as described for the GPS antenna.

MAINTENANCE
8 MAINTENANCE
This section describes simple maintenance procedures that should be performed by the system operator.
20221438 / A
75
Simrad AI70 Automatic Identification System
8.1 General
All units in the AI70 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 AI70 system units
A damaged unit that has to be shipped back to Simrad, should be sent in the original transportation box or another appropriate box. The return address is provided in the last pages of this manual.
8.2 Periodic Maintenance
The AI70 system 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.
MKD Unit
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 Station
A properly operating Mobile station 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.
76
20221438 / A
MAINTENANCE
Connection Box
It is advisable at the start of each season to check all terminal block connections in the Connection box.
8.3 Repair and modifications
The units in the AI70 system are not designed for customer repair. All repairs and modifications of the units should be carried out by Simrad qualified personnel. A failed unit should be shipped back to Simrad for repair.
Caution!
Exchanging Antenna Cables
1. Disconnect the power cable from the Connection box.
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 54.
5. Connect the antenna cable to the AI70 Mobile Station and reapply power.
If the antenna cable is attached to the Mobile Station, do not attach the antenna cable to the antenna with the AI70 powered on. If the antenna cable is short-circuited with power on, the
GPS receiver within the unit can be damaged.
20221438 / A
77
Simrad AI70 Automatic Identification System
Caution!
Exchanging GPS or VHF antennas
1. Disconnect the power cable from the Connection box.
2. Dismount the failed antenna.
3. Mount the new antenna on the antenna rod.
4. Connect the antenna cable to the antenna.
5. Seale the connection between the antenna and the antenna cable against water penetration as described in page 54.
6. Connect the antenna cable to the AI70 Mobile Station and reapply power.
If the antenna cable is attached to the Mobile unit, do not attach the antenna cable to the antenna with the AI70 powered on. If the antenna cable is short-circuited with power on, the
GPS receiver within the unit can be damaged.
8.4 Software Updates
The software in AI70 system can be upgraded to latest version in the field by connecting an external PC to the AI70 Connection box. A software upgrade has to be performed by Simrad service people or representatives.

- Remove the + 24 V power supply cable and then reapply power.
9.2 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
80
20221438 / A
Caution!
20221438 / A
TROUBLESHOOTING
Power supply failing
If the
PWR
LED on the front of the Mobile station not has green light, the system does not receive power. Use the following procedure to check for power failure:
1. Check that external power has been connected to terminal
37 to 40 in the Connection box according to page 49.
2. Verify that supplied power is in accordance with technical power specifications, page 34.
If the system outputs an alarm, the alarm condition can be read from the display.
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 shelf should be infinite if there is no short-circuit in the cable. Make a shortcircuit 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 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 to be short-circuited. Measure between centre conductor and shield. Resistance should be close to 0 Ohm.
Switch off the power before disconnecting the antenna!
GPS receiver failing
If the
GPS
LED on the front of the Mobile station not have green light, no GPS PPS pulse is received. The AI70 system computes no position data, and the GPS receiver inside the
Mobile station should be checked.
Disconnect the antenna cable at the rear side of the Mobile station. 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 station starts up as normal. If not, consult Simrad for advice.
81
Simrad AI70 Automatic Identification System
VHF transceiver failing
If the VHF antenna and antenna cabling is OK, but the
MSG
lamp on the front of the mobile station toggle between green and amber light, this indicates incorrect data reception on AIS channel 1 and 2. Disconnect and reconnect power to see if the
Mobile station starts up as expected. If not, consult Simrad for advice.
9.3 External data interface problems
External data connections may be incorrect:
· Data input from main GPS source
· Heading from vessel heading sensor
Data input from main GPS/GNSS source
Position data input to the AI70 system is received from the vessel’s main GPS/GNSS receiver using serial line communication. If data not is received in the AI70 Mobile station, the following steps should be taken in order to check for missing position data:
1. Check that cable connections are correctly terminated in the Connection box. Refer Terminal Block, page 49.
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 the
MKD unit) end.
3. 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
Simrad for advice.
82
20221438 / A
TROUBLESHOOTING
Heading from vessel heading sensor
Heading data is received from the vessel’s gyro or magnetic compass. If input data is missing, the following steps should be taken in order to check for missing heading data:
1. Check that cable connections are correctly terminated in the Connection box. Refer Terminal Block, page 49.
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.
If the mobile station still does not receive heading data, consult
Simrad for advice.

12.3 IEC 61162-1
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 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.
20221438 / A
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.

APPENDIX
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
NOTE 2
20221438 / A
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 Message ID is a general broadcast (ITU-R M.1371 messages
8 or 14), this field is null.
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.
103
Simrad AI70 Automatic Identification System
NOTE 3
NOTE 4
NOTE 5
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.
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 sequential message identifier from BBM-sentence,
IEC 61162-1 no source, field shall be null
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 acknowledgement process active for the acknowledgement that was received.
104
20221438 / A
APPENDIX
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
20221438 / A
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
105
Simrad AI70 Automatic Identification System
NOTE 2
NOTE 3
NOTE 4
NOTE 5
NOTE 6 fields. Successive sentences may use null fields for fields that have not changed, such as fields 4, 5, and 6.
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.)
The MMSI of the AIS unit which is the destination of the message.
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.
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.
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.
106
20221438 / A
APPENDIX
This sentence is used to both enter and obtain channel management information. When sent to an AIS unit, the ACAsentence 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
NOTE 2
20221438 / A
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.

This field should be null when the sentence is sent to an AIS.
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.
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
20221438 / A
APPENDIX 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 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
NOTE 2
20221438 / A
Identifies the first distant AIS being interrogated. Two messages can be requested from the first AIS.
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),
109
Simrad AI70 Automatic Identification System
NOTE 3
NOTE 4
Message 20, Data Link Management Message,
Message 22, Channel Management.
This field is used to request a message that has been further subdivided into alternative data structures. When requesting messages with alternative data structures, this message subsection identifier must be provided, so that the correct subdivision of the message data is provided. If the message structure is not sub-divided into different structures, this field should be null.
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 ABKsentence.)
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 ABKsentence

APPENDIX
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.
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 BBM-sentence. (See ABK, 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 on channel A and another sent on channel B.
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 "6bit" symbols in a sentence must be adjusted so that the total number of characters in a sentence does not exceed the "82character" 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.

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.
NOTE 1
NOTE 2
NOTE 3
112
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.
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.
This is the nine-digit number that uniquely identifies the specific
AIS that should respond. This field is null when the
20221438 / A
NOTE 4
APPENDIX interrogation is for a geographic region. When addressing a specific AIS, it is not necessary to provide the geographic coordinates of the region.
The geographic region being interrogated is a "rectangular" area defined by the latitude and longitude of the north-east and southwest corners. These fields should be null when interrogating a specific AIS. (See note 2.)
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 LR1sentence. 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 LRFsentence 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
NOTE 2
20221438 / A
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.
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
113
Simrad AI70 Automatic Identification System
NOTE 3 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)
O = Draught
P = Ship/Cargo
U = Ship's: length, breadth, type
W = Persons on board
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.)

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.
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.
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.

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 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).
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.

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.
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.
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.
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.

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

APPENDIX
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. All data fields must be provided null fields used only when data is temporarily unavailable.

Easterly variation (E) subtracts from true course. Westerly variation (W) adds to true course.
Positioning system Mode indicator:
A = Autonomous mode
D = Differential mode
E = Estimated (dead reckoning) mode
M = Manual input mode
S = Simulator mode
N = Data not valid

NOTE 3 The positioning system Mode indicator field supplements the positioning system Status field (field No. 2) which shall be set to
V = invalid for all values of Mode indicator except for A =
Autonomous and D = Differential. The positioning system Mode indicator and Status fields shall not be null fields.
All fields, except Magnetic variation is used by the AIS.
ROT – Rate of turn
IMO Resolution A.526. Rate of turn and direction of turn.
All fields are used by the AIS.
TXT – Text transmission
For the transmission of short text messages. Longer text messages may be transmitted by using multiple sentences.
NOTE 1
NOTE 2
NOTE 3
Text messages may consist of the transmission of multiple messages all containing identical field formats. The first field specifies the total number of messages, minimum value = 1. The second field identifies the order of this message (message number), minimum value = 1. For efficiency, it is recommended that null fields be used in the additional sentences, otherwise data is unchanged from the first sentence.
The text identifier is a number, 01 to 99, used to identify different text messages.
ASCII characters, and code delimiters if needed, up to the maximum permitted sentence length (i.e. up to 61 characters including any code delimiters).
All fields are used by the AIS.
