AIS – Automatic Identification System

AIS is an identification system that uses VHF communication to transmit and receive AIS data. AIS operates primarily on two dedicated VHF channels, AIS 1 – 161,975 MHz and AIS 2 – 162,025

MHz. Where these channels are not available regionally, the AIS can be set to alternate designated channels.

The AIS mobile station broadcasts the vessel's position, speed and course over ground as well as static and voyage related information.

Short safety related text messages can be sent between vessels or broadcast from shore based AIS stations or Aids to Navigation like buoys and lighthouses. The on-board installed mobile station is designed to operate automatically and as a stand-alone unit. When not transmitting, the mobile station listens for position information from other vessels or shore based stations.

GNSS Satellites

AIS Base Station

AIS VHF Link

AIS VHF Link

VTS Centre

Figure 1 Elements in an AIS system

The system broadcasts data using the SOTDMA (Self-organised Time

Division Multiple Access) data protocol. Each minute is divided into

4500 time slots, enabling simultaneous transmission of up to 500 stations.

Coverage

The system radio coverage range is similar to other VHF applications and is dependent on the height of the antenna. The propagation differs from that of a radar, due to the longer wavelength, so it is possible to

"see" around bends and behind islands if the landmasses are not too high. A typical value to be expected at sea is 20 nautical miles.

AIS information content

AIS type of information is exchanged automatically between vessels, vessels and shore based stations and vessel and Aids to Navigation like buoys and lighthouses. The information transmitted by the AIS mobile stations is grouped in four categories:

Static Data

•

MMSI (Maritime Mobile Service Identity) number

•

Call sign and name

•

IMO number

•

Length and beam

•

Type of ship

•

Location of position fixing antennas on the ship

Voyage Related Data

•

Ship's draught

•

Hazardous cargo type

•

Destination and ETA (at Master's discretion)

Dynamic Data

•

Position with accuracy indication and integrity status

•

Time in UTC

•

COG (Course over ground)

•

SOG (Speed over ground)

•

Heading

•

Navigational status

•

Rate of turn

Safety-related Messages

•

Reading and writing short safety related messages

Data reporting and transmission rates

AIS data as stated above is autonomously sent at different update rates and thus reporting rates are dependent on the ship's navigational mode. Dynamic information is dependent on speed and course alteration while static and voyage related data are transmitted every 6 minutes or on request. Thus fast ferries will report their navigational data at a higher update rate than ships at anchor.

System components

The Seatex AIS 100 system consists of the following units:

Figure 2 AIS 100 system components

6


AIS 100 Minimum Keyboard and Display (MKD)

The MKD unit provides a simple user interface to the mobile station.

The keypads on the MKD can be used to navigate between dedicated menus used for configuration and display of vessel navigation data.

Text messages can also be entered into the MKD and transmitted to other vessels or shore based AIS stations providing warnings or other relevant navigation information. Thus the MKD provides basic presentation of configuration data, position data and text messages. If the AIS has been interfaced to the on-board ECDIS system or radar the information displayed on the MKD can also be displayed on an

AIS compatible ECDIS or ECS systems.

AIS 100 mobile station

The mobile station incorporates two VHF receivers, configured to operate on the predefined AIS frequencies for the region, one VHF transmitter transmitting on all required frequencies and one DSC receiver. The mobile station also incorporates a GPS receiver and a processor. The internal GPS receiver, which is capable of receiving differential corrections for increased position accuracy, is used for time synchronisation and as a backup position sensor. For AIS data transmission, the Self Organised Time Division Multiple Access

(SOTDMA) data protocol is used. SOTDMA enables a large number of vessels to receive and transmit AIS data at the same time.

Front LED indicators

The LED indicators on the front of the mobile station can be used to monitor status as well as data reception and transmission.

AIS 100 connection box

The connection box is used to connect to external sensors main position sensor, heading sensor and rate of turn sensor (when available). These sensors are mandatory while interfaces to electronic hart systems and long range communication systems, are optional.

AIS compatible ECDIS/ECS systems are interfaced to the AIS through serial line communication. Power is supplied to the AIS mobile station through the connection box.

AIS 100 VHF antenna

The VHF antenna is used for VHF communication. The antenna is connected to the mobile station using cables with attenuation less than

3 dB.

AIS 100 GPS antenna

The GPS antenna is an L1 antenna receiving signals from all visible satellites. The antenna is hermetically sealed and the cable used to connect the GPS antenna to the mobile station should be of a quality that ensures minimum loss of signal, i.e. less than 20 dB.

Seatex AIS 100 Instruction Manual, rev. 5 Operation

2 OPERATION

2.1

Introduction

The AIS should always be in operation. It is recommended not to switch off the AIS during port stays in order to provide information to port authorities. In areas where piracy occurs, the master may switch of the transmitter. If the transmitter is switched off, static data and voyage related information will be stored.

2.2

Operational modes

After the unit has been installed and configured it operates automatically without any user intervention. The mobile station has three operational modes:

•

Autonomous and Continuous mode

•

Assigned mode

•

Polled or Controlled mode

2.2.1

Autonomous and continuous mode

In the Autonomous and Continuous mode the mobile station automatically defines its own reporting rate in accordance with its navigational mode, speed and course. The unit also selects its own data transmission slots. This is the normal mode for operation in all areas but the mode may be switched to/from Assigned mode or Polled or Controlled mode by a competent authority via a base station on shore.

2.2.2

Assigned mode

A competent authority responsible for traffic monitoring may remotely set transmission intervals and/or time slots for the vessel mobile station. When operating in Assigned mode, the mobile station will transmit position data on a slightly different format, AIS Message

Type 2, instead of the transmitted AIS Message Type 1. In Assigned mode the mobile station does not change its reporting rate when changing course and speed. Assignments are limited in time and will be re-issued by the competent authority when needed. Thus, Assigned mode only affects the transmission and not the reception of position reports.

9


2.2.3

Polled or controlled mode

In this mode the mobile station will automatically respond to interrogation messages from a ship or competent authority. The response is transmitted on the channel where the interrogation message was received. Operation in Polled or Controlled mode does not conflict with operation in the other two modes.

2.3

Malfunction and fallback arrangements

The mobile station has built-in integrity testing to continuously verify own operational status and notify user and external equipment if any malfunction is detected. Part of this test monitors the transmitter and receiver modules. Alarm status will be transmitted to the PI port in addition to triggering the alarm relay.

2.4

Mobile station initialisation

The mobile station will automatically switch on when power is applied to the unit by connecting the power cable in the connection box. There is no on/off switch and thus power is removed by disconnecting the power cable in the connection box.

•

After power has been applied, wait for the two-minute initialisation period.

•

At completed initialisation all LEDs will go amber.

•

The mobile station is ready for operation when the GPS LED is blinking at one-second intervals.

•

The View page will appear on the MKD.

The Edit Current Region page enables the operator to change channels for the two AIS radio receivers. The TxPower can only be set to High or

Low. If High is selected, the transmission power is set to 12.5 W and if Low is selected, the transmission power is set to 2 W. BW A and BW

B is the bandwidth settings for the VHF.

The selections are Default or Narrow. Default is the maximum bandwidth allowed for this channel

(25 kHz or 12.5 kHz). Narrow denotes 12.5 kHz.

The user is only allowed to decrease the bandwidth. Zone denotes the size of the transition area in nautical miles outside of the region.

The View Regions page displays all defined regions. This is a read only page and thus no configuration changes can be made. The view regions may consist of up to 8 pages and the

ARROW DOWN button can be used to display more regions.

5.2

AIS 100 MKD

Typically the MKD unit is installed in a dedicated hole in one of the bridge consoles or fitted to the bulkhead at a place where the information easily can be monitored by the navigator. For the physical installation, screws can be mounted in the four holes hidden behind the cover on each corner of the unit or used to fasten the bracket following the MKD. Ensure enough space behind the MKD unit for connecting the Amphenol connector properly without bending the cable.

External cabling of data signals

Shielded twisted pair cables shall be used for the high-speed serial data ports. The recommended wiring (the figures below are excerpts from IEC 61162-2, ed. 1) is as shown on the drawings. The A, B and

C designation correspond with the data signals as listed in the tables on the preceding pages. There may be several listeners (receivers) but only one talker (transmitter). For long lines we recommend to use a terminating resistor (120 Ohm between A' and B' at the receiving end). Avoid stubs or make them as short as possible. The common wire designated "C" is the signal ground reference and this wire shall be isolated from the outer shielding. The outer cable shield shall be continuous (unbroken) through the installation, but shall not be terminated to any part of the receiver.

Figure 16 Talker and listener cabling – data/shield

Shielded twisted pair cable with third-wire is shown below. The common "C" wire may be one wire of a pair of another port's common connection wire "C", if they have the same destination.

Figure 17 Third wire cabling

When the AIS connection box is used, the cable shields will be continuous from the mobile station to the external installation when the external cables' shield is properly terminated in the nipples' metal tongues.

AIS 100 VHF antenna

The range for receiving VHF signals relates directly to the height of the antenna above sea level as well as the general on-board conditions for reception and transmission of radio signals. For optimum AIS radio performance the following should be taken into consideration:

VHF antenna installation

•

It is recommended that the AIS VHF antenna should be placed in a position with a minimum of 2 metres in horizontal direction from constructions made of conductive materials.

•

The antenna should not be installed close to any large vertical obstruction and there should be a free view of the horizon through

360 degrees.

•

The antenna should be installed safely away from interfering high power energy sources like radar and other transmitting radio antennas, preferably at least 3 metres away from and out of the transmitting beam and there should not be more than one antenna on the same level.

•

The antenna should be mounted directly above or below the ships primary VHF radiotelephone antenna, with no horizontal separation and with a minimum of 2 metres vertical separation. If located on the same level as other antennas, the distance apart should be at least 10 metres.

When installed straight above the ship's radio antenna, the vertical separation should be 2.0 m

Figure 18 Recommended VHF antenna installation

42


Antenna cabling

•

The cable should be kept as short as possible to minimise attenuation of the signal. A double shielded coaxial cable equal or better than RG-214 is recommended.

•

All outdoor installed connectors on the coaxial cables should be fitted with preventive isolation such as shrink stocking with glue to protect against water penetration into the antenna cable.

•

Coaxial cables should not be exposed to sharp bends, which could change the characteristic impedance of the cable. The minimum bend radius should be 5 times the cable diameter.

VHF antenna cable connection

The following procedure should be used for proper mounting of cable connectors:

Figure 19 VHF and GPS antenna cable connector termination

43


VHF antenna cable lengths

Maximum cable lengths depend on the attenuation factors of the cables used. The total attenuation of the VHF antenna cables should be less than 3 dB for proper operation as higher attenuation will reduce the coverage area of the mobile station. The cable connectors must be of a type that is designed for the actual cable.

AIS 100 GPS antenna

GPS antenna installation

Optimum location of the GPS antenna is important to ensure continuously track of all visible GPS satellites used for time synchronisation and computation of backup position fix. The following should be taken into consideration during installation:

•

The GPS antenna must be installed where it has a clear view of the sky and thus the objective is to see the horizon freely through 360 degrees with a vertical observation of 5 to 90 degrees above the horizon.

•

Small diameter obstructions, such as masts and booms, do not seriously degrade signal reception but such objects must not eclipse more than a few degrees of any given bearing.

•

Locate the antenna at least 3 metres away from and out of the transmitting beam of high power transmitters (S-band radar and/or

Inmarsat systems). This includes the ship's own AIS VHF antenna if it is located separately.

GPS antenna cabling

•

To achieve optimum performance, the gain of the antenna preamplifier should match the cable attenuation. The resulting installation gain (pre-amplifier gain – cable attenuation) should be within 0 to 10 dB.

•

The coaxial cable between the antenna and the AIS mobile station should be routed directly in order to reduce electromagnetic interference effects.

GPS antenna cable lengths

The GPS antenna cable should have a total attenuation of less than 10 dB as higher attenuation may degrade the quality and accuracy of the position data.

Cable type

RG214

Low loss ½" Superflex

Max. length

100 metres

Applying power

After the mechanical and electrical installation is completed the coaxial cables should be checked for short circuit between centre conductor and shield (ground) with the antenna disconnected. If not short-circuited, power could be applied to the mobile station.

45


Sealing of GPS and VHF antenna connectors

•

Ensure that the outdoor antenna connectors are wrapped with waterproof self-vulcanising tape.

•

Stretch the tape to double length and start wrapping a bit down on the cable.

•

Wrap the tape all over the connectors and, if possible, seal it with electric coating.

•

An alternate way of waterproofing is to use heat shrinkable hose with glue.

•

The hose should cover the whole connector and part of the cable and finally it should be sealed with electric coating.

5.8

Internal alarm system

The Seatex AIS 100 has a built-in alarm functionality. The alarm is generated in different ways:

•

Alarm generated by the BIIT.

•

Alarm generated by the sensor part.

•

Alarm generated by the MKD.

An alarm could cause different actions taken by the system, depending on the nature of the alarm. An alarm generated by the BIIT could stop transmission of messages. An alarm will open the alarm relay, which can be used to trigger an external alarm. There will also be generated an alarm message on the PI port which can be read on an MKD, if connected, or on an external interfaced system.

There are two types of alarm messages, which can be output on the PI and LAN port. An ALM message, e.g. $AIALM, is output when an error situation arises. A TXT message, e.g. $AITXT, is output when there is an indicator message. An error situation may arise if there is a

TX malfunction, while an indicator message may arise when differential corrections are lost. The ALM LED in the front of the AIS

100 will be lit if an error situation arises.

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 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 .

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

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.

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:

= 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

52

Seatex AIS 100 Instruction Manual, rev. 5 External interfaces acknowledgement process active for the acknowledgement that was received.

ABM – Addressed Binary and safety related message

This sentence supports ITU-R M.1371 messages 6 and 12. It provides an external application with a means to exchange data using an AIS.

The message data is defined by the application only – not the AIS.

This message offers great flexibility for implementing system functions that use the AIS like a communications device. After receiving this sentence, the AIS initiates a radio broadcast on the VHF

Data Link (VDL) of either message 6 or 12. The AIS will make up to four broadcasts of the message. The actual number will depend on the reception of an acknowledgement from the addressed "destination"

AIS. The default time between retries is 4 s. Retries will not be attempted more frequently than 4 s. Retries stop when the appropriate acknowledgement (See ITU-R M.1371 messages 7 and 13.) is received. The AIS will make up to 4 broadcasts, original broadcast plus three retires. This process could take 32 s to complete.

The success or failure of the reception of this broadcast by the intended AIS unit is confirmed through the use of the "Addressed and binary Broadcast Acknowledgement (ABK)" sentence formatter, and the processes that support the generation of an ABK-sentence. The

AIS is also limited in the amount of encapsulated data that can be sent in each slot and frame. If the length of the message would exceed five slots, or the AIS broadcast would exceed the limit of 20 RATDMA slot transmissions for the current frame, the AIS will return an ABKsentence with an acknowledgement of "2" – message could not be broadcast.

NOTE 6

External interfaces identifies the order of this sentence in the message, minimum value 1.

All sentences contain the same number of fields. Successive sentences may use null fields for fields that have not changed, such as fields 4,

5, and 6.

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.

54


This sentence is used to both enter and obtain channel management information. When sent to an AIS unit, the ACA-sentence provides regional information that the unit stores and uses to manage the internal VHF radio. When sent from an AIS unit, the ACA-sentence provides the current channel management information retained by the

AIS unit. The information contained in this sentence is similar to the information contained in an ITU-R M.1371 message 22. The information contained in this sentence directly relates to the

"Initialisation Phase" and "Dual Channel operation and Channel management" of the AIS unit as described in ITU-R M.1371.

NOTE 1

NOTE 2

NOTE 3

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 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

56

Seatex AIS 100 Instruction Manual, rev. 5 External interfaces 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 4

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),

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 sub-division 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

57

Seatex AIS 100 Instruction Manual, rev. 5 External interfaces 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 2

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.

External interfaces 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.)

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 "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.


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 .

NOTE 1

NOTE 2

NOTE 3

NOTE 4

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 interrogation is for a geographic region. When addressing a specific AIS, it is not necessary to provide the geographic co-ordinates of the region.

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.)

60


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

NOTE 2

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 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)

61


NOTE 3

External interfaces

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

65


NOTE 5

External interfaces 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.

NOTE 1

NOTE 2

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 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.

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.


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.

ALR – Set alarm state

Local alarm condition and status. This sentence is used to report an alarm condition on a device and its current state of acknowledgement.

DTM - Datum reference

Local geodetic datum and datum offsets from a reference datum. This sentence is used to define the datum to which a position location, and geographic locations in subsequent sentences, are referenced.

Latitude, longitude and altitude offsets from the reference datum, and the selection of the reference datum, are also provided.

Cautionary notes: The datum sentence should be transmitted immediately prior to every positional sentence (e.g. GLL, BWC, WPL) which is referenced to a datum other than WGS84, the datum recommended by IMO.

For all datums the DTM sentence should be transmitted prior to any datum change and periodically at intervals of not greater than 30 s.

GBS – GNSS satellite fault detection

This message is used for setting the RAIM flag in the position reports sent by the AIS.

NOTE 1 Expected error in metres due to bias, with noise = 0.

Satellite ID numbers. To avoid possible confusion caused by repetition of satellite ID numbers when using multiple satellite systems, the following convention has been adopted: a) GPS satellites are identified by their PRN numbers, which range from 1 to 32.

b) The WAAS system has reserved numbers 33 – 64 to identify its satellites.

c) The numbers 65 – 96 are reserved for GLONASS satellites.

GLONASS satellites are identified by 64+ satellite slot numbers.

The slot numbers are 1 through 24 for the full GLONASS constellation of 24 satellites, thus giving a range of 65 through 88.

The numbers 89 through 96 are available if slot numbers above 24 are allocated to on-orbit spares.

Only Expected error in latitude and Expected error in longitude is required and used by the AIS.

GGA – Global positioning system (GPS) fix data

GNS – GNSS fix data

Fix data for single or combined satellite navigation systems (GNSS).

This sentence provides fix data for GPS, GLONASS, possible future satellite systems and systems combining these. This sentence could be used with the talker identification of GP for GPS, GL for GLONASS,

GN for GNSS combined systems, as well as future identifiers. Some fields may be null fields for certain applications, as described below.

If a GNSS receiver is capable simultaneously of producing a position using combined satellite systems, as well as a position using only one of the satellite systems, then separate $GPGNS, $GLGNS, etc.

messages may be used to report the data calculated from the individual systems.

If a GNSS receiver is set up to use more than one satellite system, but for some reason one or more of the systems are not available, then it may continue to report the positions using $GNGNS, and use the mode indicator to show which satellite systems are being used.

NOTE 1 Mode Indicator. A variable length valid character field type with the first two characters currently defined. The first character indicates the use of GPS satellites, the second character indicates the use of

GLONASS satellites. If another satellite system is added to the standard, the mode indicator will be extended to three characters; new satellite systems shall always be added to the right, so the order of characters in the Mode Indicator is: GPS, GLONASS, other satellite systems.

The characters shall take one of the following values:

N = No fix. Satellite system not used in position fix, or fix not valid.

A = Autonomous.Satellite system used in non-differential mode in position fix.

D = Differential. Satellite system used in differential mode in position fix.

Seatex AIS 100 Instruction Manual, rev. 5 Maintenance

8 MAINTENANCE

8.1

General

The Seatex AIS 100 consists of both software and hardware. The software part can be reinstalled or upgraded to the latest version in the field by running a software installation procedure. Service of the

Seatex AIS 100 hardware in the field can consist of:

•

Exchange of damaged GPS or VHF antenna cables.

•

Exchange of failed GPS or VHF antennas.

•

Exchange of failed Seatex AIS 100 mobile station .

The Seatex AIS 100 requires a skilled technician to maintain most of the hardware service.

8.2

Periodic maintenance

The AIS 100 should regularly be checked for firm and fixed mounting of the chassis in order to avoid vibration and shock. All connectors should be checked for good mechanical and electrical connections.

Cables should not be bent more than the minimum recommended bending radius and there should be no sharp bends on coaxial cables.

All cables should be fixed tight and rigid to their supporting structure

(bulkhead, mast etc.) and special care should be taken where cables run through holes with sharp edges.

A properly operating unit will show when it is transmitting and receiving messages by short blinks on the TX and MSG LEDs.

Inspecting the LEDs for normal operation gives a good indication of the operating status. In particular, there should be no red LEDs, because red indicates alarms or severe faults. Any red LED indication means that further investigation and servicing is necessary.

8.3

Repairs and modifications

Repair of the Seatex AIS 100 consists of exchange of damaged antenna cables, exchange of GPS or VHF antenna and replacement of the Seatex AIS 100 mobile station, connection box or MKD. Any skilled electrician should be able to do this.

89


8.3.1

Exchange of antenna cable

1.

Disconnect the power cable from the Seatex AIS 100.

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.

The connection between the antenna and the antenna cable should be sealed against water penetration, preferably by using waterproof self-vulcanising tape or shrink stocking with glue.

5.

Connect the antenna cable to the Seatex AIS 100 unit and reapply power by connecting the power cable.

Caution!

If the antenna cable is attached to the unit, do not attach the antenna cable to the antenna with the Seatex AIS 100 powered on.

If the antenna cable is short-circuited with power on, the GPS receiver within the unit can be damaged.

8.3.2

Seatex AIS 100 Instruction Manual, rev. 5 Troubleshooting

9 TROUBLESHOOTING

If the initialisation process fails, the alarm LED will turn red. Mobile station failure can be divided into two categories:

•

Hardware problems

•

External interface problems

9.1

Hardware problems

Hardware problems can be divided into the following categories:

•

Power supply failing

•

GPS receiver failing

•

VHF transceiver failing

•

GPS and VHF antennas and cables

•

Interface cables

9.1.1

Power supply failing

If the lamp PWR on the front of the mobile station does not light green, the unit does not receive power. First check the fuse in the connection box. If the fuse is OK, check that external power has been connected to terminal screws 37 to 40 in the AIS 100 connection box as stated in section 5.4 and that the supplied power is in accordance with technical power specifications, section 4.3. If the transponder outputs an alarm, the alarm condition can be read from the display.

9.1.2

GPS and VHF antenna cable connections

Typical problems when no GPS signal is received is that the GPS antenna cable and/or connectors are damaged as well as loose or that the cables are not properly connected. In order to check for antenna cable problems, ensure that the GPS antenna is disconnected. The

Ohm reading between the centre and the shelf should be infinite if there is no short-circuit in the cable. Make a short-circuit in the opposite end of the cable and measure the resistance. Now the reading should be approximately 0 Ohm.

9.1.3

GPS and VHF antenna malfunction

Disconnect the GPS antenna cable at the rear side of the mobile station. Measure the resistance between the centre pin and shield in the cable (with the antenna connected). The GPS antenna does not have a defined resistance that can be measured. Therefore, before measurements can be carried out, the antenna end of the cable needs

93

Seatex AIS 100 Instruction Manual, rev. 5 Troubleshooting 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.

Note!

9.1.4

GPS receiver failing

If the mobile station does not compute position data and the GPS lamp on the front of the mobile station does not light green, the GPS PPS pulse is not being received and the GPS receiver inside the mobile station should be checked. Disconnect the antenna cable at the rear side of the hardware unit. The voltage output on the GPS antenna connector should be approximately 4.8 – 5.0 V and indicates that the

GPS receiver supplies voltage to the antenna. If not, this indicates problems with the GPS receiver. Disconnect and connect power (a few times) and see if the mobile station starts up as normal. If not, consult Seatex for advice.

9.1.5

VHF transceiver failing

If the VHF antenna and antenna cabling is OK and the MSG lamp on the front of the mobile station does not light green and amber vice versa, this indicates incorrect data reception on AIS channel 1 and 2.

Disconnect and connect power (a few times) and see if the mobile station starts up as expected. If not, consult Seatex for advice.

9.2

External data interface problems

External data connections may be incorrect:

•

Data input from main GPS source

•

Heading from vessel heading sensor

9.2.1

Data input from main GPS/GNSS source

Position data output from the AIS mobile station is generated from the vessel main GPS/GNSS receiver and received into the AIS unit using serial line communication. If data is missing into the AIS mobile station, the following steps should be taken in order to check for missing position data:

•

Check that cable connections are correctly terminated in the connection box (terminal screws 19 to 27).

•

If properly connected, check the serial line communication (baud rate, parity, number of bytes transmitted, number of stop bits)

94

Seatex AIS 100 Instruction Manual, rev. 5 Troubleshooting between transmitting (vessel GPS/GNSS receiver) and receiving

(parameters to be checked from the MKD unit) end.

•

If OK, check that the position output format from the GPS/GNSS receiver is in accordance with the expected input position format.

•

If the mobile station still does not receive position data, consult

Seatex for advice.

9.2.2

Heading from vessel heading sensor

Heading data is received from the vessel gyro or magnetic compass. If input data is missing, the following steps should be taken in order to check for missing heading data:

•

Check that cable connections are correctly terminated in the connection box (terminal screws 19 to 27).

•

If correctly connected, check the serial line communication (baud rate, parity, number of bytes transmitted, number of stop bits) between transmitting (vessel heading sensor) and receiving

(parameters to be checked from the MKD unit) end.

•

If OK, check that the heading output format from the compass is in accordance with the expected input heading format.

•

If the mobile station still does not receive heading data, consult

Seatex for advice.

If the mobile station fails to operate properly, remove power by removing the + 24 V power supply cable and then reapply power. The mobile station should now initialise from start.
