SECTION 1 - WHAT IS AIS?

1. Overview

AIS is an acronym for Automatic Identification System. AIS increases navigational safety and collision avoidance by transmitting vessel identification, helping to reduce the difficulty of identifying ships when not in sight (e.g. at night, in radar blind arcs or shadows or at distance) by broadcasting navigational intentions to other vessels by providing ID, position, course, speed and other ship data with all other nearby ships and land based stations.

According to International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) regulations, AIS is defined as follows: AIS is a broadcast transponder system, operating in the VHF maritime mobile band. It is capable of sending ship information such as identification, position course, speed and more, to other ships and to shore. It can handle multiple reports at rapid update rates and uses Carrier Sense Time Division Multiple Access (CSTDMA) technology to meet these high broadcast rates and ensure reliable and robust ship to ship operation.

The International Maritime Organization (IMO) defines the performance standards as follows: Ship to ship working, ship to shore working, including long range application, automatic and continuous operation, provision of information messaging via PC and utilization of maritime VHF channels

The Modules: GPS system, AIS Transponder, VHF Antenna, and the Data Power Cable (appropriate application software connects the individual modules).

AIS are required to function flawlessly in a variety of modes. The regulations require that the system be capable of:

An "autonomous and continuous" mode for operation in all areas. This mode shall be capable of

being switched to/from one of the following alternate modes by a competent authority;

An "assigned" mode for operation in an area subject to a competent authority responsible for traffic

monitoring such that the data transmission interval and/or time slots may be set remotely by that authority;

A "polling or controlled" mode, where the data transfer occurs in response to interrogation from a ship

or competent authority.

This illustration depicts a typical AIS System, where two or more AIS equipped vessels (and shore based systems) are automatically communicating with each other.

Y1-03-0222 Rev. C

On the bottom, a typical Nauticast™-B AIS installation in a common environment is shown. The Nauticast™-B AIS is connected to the vessel‟s power supply, and, in connection with the VHF and GPS antennas, the minimal requirements for transponder operation are fulfilled.

Both vessels in the above illustration are equipped with an AIS transceiver. Due to “Time – Synchronization”, they use the same organization of free and allocated windows (slots) in the shared VHF Data Link (this method is called “Carrier Sense Time Division Multiple Access”) to send and receive messages. Without the necessity of any operator interaction, both vessels know exactly who or what is cruising nearby and where the individual object is heading.

The scenario below shows a full AIS coverage area (including all applications and complete shore infrastructure).

2. AIS classes

There are two classes of AIS units fitted to vessels, Class A and Class B. In addition, AIS base stations may be employed by the Coast Guard, port authorities and other authorized bodies. AIS units acting as Aids to Navigation (A to N) can also be fitted to fixed and floating navigation markers such as channel markers and buoys.

Class A units are a mandatory fit under the Safety of Life at Sea (SOLAS) convention to vessels above 300 gross tons, or which carry more than 11 passengers in international waters. Many other commercial vessels and some leisure craft also may be fitted with Class A units.

Class B units are designed for fitting in vessels which do not fall into the mandatory Class A fit category.

ACR Nauticast™-B Automatic Identification System is a Class B AIS unit.

NOTE: For information reporting intervals, see Specifications appendix

In order to meet carriage requirements for Class A and Class B AIS systems, dedicated GPS and VHF antennas must be fit to the transponders. ACR has included GPS and VHF antennas that have been specifically designed, tested and approved for use with the Nauticast™-B. ACR Electronics Inc. does not recommend or support using other antennas or sharing data information from existing shipboard installations.

Class B AIS transponders will transmit data to other AIS equipped vessels and shore base stations. Static data typically identifies the vessel and does not change (i.e. MMSI, Vessel Name). Dynamic data is voyage specific and will change during the normal operation of the vessel.(i.e. Speed Over Ground, Position, Heading).

In order to complete the programming of your AIS transponder, documentation of your vessel‟s identity needs to be made available. This would be a good time to update any information that is inaccurate in the MMSI data base or with your ship‟s radio station license. These databases should be reviewed periodically to make sure the information is accurate including your emergency contact information.

Per FCC rules (United States users only) the static data can only be programmed into an AIS Transponder by the vendor or qualified personnel. Once the static data is programmed into an AIS Transponder it can only be corrected by ACR Electronics. Please check that the static data are entered carefully. If the static data are incorrectly programmed the transponder will need to be returned to ACR for factory reset.

Information transmitted from vessels that have a Class A AIS transponders on-board include:

NOTE: The marine AIS system uses position information derived from networks such as the Global Positioning Satellite (GPS) or the Global Navigation Satellite System (GLONASS) to determine the location of the AIS unit and thus the vessel to which it is fitted. The Nauticast™-B AIS utilizes the GPS satellite network.

It is desirable wherever possible therefore to verify both your vessel‟s AIS derived position data and other

vessels‟ AIS derived position data with visual or radar based observations.

10. INSTALLERS ONLY: Entering static data

Select the Monitoring tab and open the static data tab. This will display the static data for the connected AIS transponder. This includes the vessel's name, call sign, MMSI number and other fixed information.

Y1-03-0222 Rev. C

To configure the transponder all of the data fields must be completed and saved to the AIS.

WARNING:

Per FCC rules (United States users only) the static data of the vessel cannot be changed once

programmed. Do not program the static data unless you are certain you have the correct information. Please check the number entered carefully. If the static data programmed is incorrect the AIS transponder will need to be returned to ACR Electronics for factory reset.

Enter the vessel‟s information in the appropriate box:

Ship's name - enter the name of the vessel (20 characters maximum) Call Sign - enter the vessel's radio call sign (7 characters maximum) (If your local authority does not require

a call sign number, enter @@@@@@@) MMSI number - enter the vessel's Maritime Mobile Service Identity number Enter the vessel‟s dimensions as follows rounded to the nearest meter

Dimension A - distance from bow to GPS antenna location to the nearest meter

Dimension B - distance from the GPS antenna location to the stern to the nearest meter

Dimension C - distance from the port side to the GPS antenna location to the nearest meter

Dimension D - distance from the GPS antenna to the starboard side to the nearest meter

Select the most appropriate vessel type from the drop down menu

CAUTION:

If no MMSI is entered then the AIS transponder will operate in receive only mode and the red

LED will remain on. The vessel‟s own position will not be transmitted. An MMSI must be entered to allow the AIS transponder to transmit its own position to other vessels.

When you have entered all of the vessel's data, double-check what you have entered for accuracy, then click the 'Save to Nauticast-B' button to program this configuration into the AIS transponder:

A warning will be displayed asking you to verify the MMSI number. The static data (including the MMSI) can only be changed by ACR Electronics once programmed into the transponder. Please check that the number displayed is correct before proceeding. If the number is incorrect click the 'No' button to cancel programming of the MMSI.

Y1-03-0222 Rev. C

Click the 'Yes' button if the MMSI is correct. The static data tab will be updated to show the

newly programmed vessel information. The MMSI number will be displayed with a grey background to indicate that it has been programmed and cannot be changed.

CAUTION:

Do not install the Nauticast™-B AIS unit in an

environment where it can be subject to excessive exposure to water.

CAUTION:

The Nauticast™-B AIS unit is designed for operation in

the temperature range -25 °C to +55 °C. Do not install (or use) the

If an external display unit (AIS capable chart plotter, MKD, etc.) is to be used, connect the data interface cable to the NMEA port. Depending on your model chart plotter, a NMEA multiplexer capable of handling AIS data (38,400 baud) may be required. Consult the chart plotter manufacturer‟s support materials for interface instructions.

Y1-03-0222 Rev. C

Only the data and power cables provided with the Nauticast™-B AIS unit should be used to

If using PC serial terminal with third party AIS capable Electronic Charting Software, connect the user end of the data interface cable to the display device. The software in the display device must be configured for AIS operation AND to accept standard Class B AIS operation NMEA sentences. This external display unit software is not part of the Nauticast™-B AIS transponder package. By rule, Class B AIS devices must output serial data. If your computer only has a USB port, you must use a serial-to-USB adapter, available at most consumer electronic retailers.

The Nauticast™-B requires a 12V DC power supply (9.6 – 15.6V) capable of supplying 2A peak surge. The power supply is a two wire system where the red wire is the positive lead and the black wire is the negative lead. The Nauticast™-B should be connected to the vessel‟s fuse panel that is supplied by the ship‟s 12V batteries.

CAUTION

isolated from this system with the use of a fully isolated DC/DC converter.

Physical mounting

The unit shall be mounted on a vertical bulkhead with the cables in the down position. The mounting location should be protected from the weather and direct water spray. Typically this would be under the helm station or in the cabin.

: If the vessel uses an AC generator that converts to DC power, the Nauticast™-B should be fully

It is recommended that the unit is attached to a solid surface with #10-32 x 1.2 self tapping head Phillips screws (provided in kit). A template for drilling pilot holes is included in this kit.

WARNING: The compass safe distance of this unit is 0.5m or greater for 0.3° deviation.

12. Antenna installation

Antenna connections on the transponder

GPS antenna This is a TNC female bulkhead connector that mounts to the side of the transponder case. This port provides the 5V DC feed for the active GPS antenna required by the Nauticast™-B AIS unit. VHF antenna This is a UHF female PL-259 bulkhead connector that mounts to the side of the transponder case.

CAUTION: The GPS, VHF and power/data cables need to be secured to the bulkhead within 6” to 12” from

the connectors. Avoid excess stress on connectors during installation. Strain relief should be used.

Antenna mounting

GPS antenna for AIS use

NOTE:

use a separate VHF antenna and a separate GPS antenna dedicated to the Class B device in order to be compliant with the regulations. Use the antennas supplied with this kit.

The GPS antenna supplied for use with the Nauticast™-B is an active type (i.e. it includes LNA) and is suitable for marine shipboard applications (index of protection, ruggedness, means of mounting, ect). The supplied antenna supplies a minimum gain of 20dB to the Nauticast™-B after subtraction of the normal loss from antenna cable and connectors. The GPS antenna used for any AIS must be a dedicated antenna , i.e. not shared with any other GPS receiver. Installation of the GPS antenna is critical for the performance of the built in GPS receiver which is used for timing of the transmitted time slots and for the supply of navigational information should the ships main navigational GPS fail.

It is strongly recommended that:

If you are installing a Class B AIS transponder on a vessel because you are required to do so, you must

The GPS antenna is mounted in an elevated position and free of shadow effect from the ship‟s

superstructure.

Y1-03-0222 Rev. C

The GPS antenna has a free view through 360 degrees with a vertical angle of 5 to 90 degrees above

the horizon.

The GNSS antenna is placed as far away as possible from radar, Inmarsat and Iridium transmitters.

Also ensure that the GPS antenna is free from direct view of the radar and the Inmarsat beam. The received GPS signal is very sensitive to noise and interference generated by other onboard transmitters.

The MF/HF and other VHF transmitter antennas are kept as far away as possible from the GNSS

antenna. It is good practice never to install a GNSS antenna within a radius of 2 meters from these antennas.

VHF antenna for AIS use

NOTE:

use a separate VHF antenna and a separate GPS antenna dedicated to the Class B device in order to be compliant with the regulations. Use the antennas supplied with this kit.

The VHF antenna supplied for use with the Nauticast™-B is omni-directional, vertically polarized with unity gain (0 dB) and a band width sufficient to maintain VSWR <1.5 over the frequency range 156–163 MHz. As a minimum the 3dB bandwidth will cover the two AIS channels and the DCS channel. The antenna is also suitable for marine shipboard applications (index of protection, ruggedness, means of mounting, etc.).

If you elect to not use the antenna supplied, the alternate VHF antenna employed for AIS use:

If you are installing a Class B AIS transponder on a vessel because you are required to do so, you must

Must be a dedicated antenna, i.e. not shared with any other VHF transmitter/receiver. Should be mounted with at least a two meter vertical separation distance from any other VHF antenna

used for speech or DCS communication. Also see Appendix for warnings such as “Radio Frequency Exposure Warning”.

SECTION 3 - USING THE TRANSPONDER

1. Switching ON

When the 12V supply is switched on, all four LEDs visible on the front panel of the unit will illuminate twice for a period of one second on each illumination. The blue LED will then go out. When the internal GPS starts outputting valid position information, the red LED will go out. When the Nauticast™-B AIS unit transmits its first position report (message 18), the yellow LED will go out. Note that this process may take up to 30 minutes depending on the switch-on state of the GPS receiver. When the yellow LED goes out the green LED will illuminate indicating that the unit is now operating correctly.

2. Warning and fault states

If the unit has not been able to transmit a position report during the last expected two reporting intervals (i.e. the nominal reporting interval cannot be maintained for operational reasons such as a Message 23 quiet period, high channel load conditions, etc.) the yellow LED will illuminate. This is a warning condition only and indicates that your vessel‟s position is not currently being reported to other vessels. Reception of other vessel AIS information by the Nauticast™-B AIS is not affected. When the unit is able to commence reporting, the yellow LED goes out.

If a fault occurs the red LED will illuminate. This may illuminate briefly if the power supply is interrupted or if the VHF or GPS antenna characteristics are briefly affected.

Y1-03-0222 Rev. C

If the red LED illuminates continuously, the unit should be assumed to be faulty. It should either be switched off (power removed) or, if this is not practical, any other vessel position information derived from the unit should not be used. It should also be assumed that the unit is not transmitting valid position information for your vessel.

The unit should be examined by a competent equipment maintainer at the earliest opportunity. More details on LED indications can be found in “LED Indicators” (below).

3. Data port messages

The data port will output the following:

(At power-up) boot-loader and main application splash text screens including version numbers, and

memory status Details of relevant AIS transmissions received Details of AIS transmissions sent Details of channel management messages received Alarm messages generated by the BIIT function

The data port will accept the following inputs:

Programming information Alarm acknowledgements

Please see the ‘Data Interface’ section of this manual for more details of the data port messages.

When in operation, an AIS unit:

Uses one of two VHF channels within the international marine band allocation (channel 87B;

161.975MHz, or channel 88B; 162.025MHz) to regularly transmit information such as the vessel

position, Maritime Mobile Service Identity (MMSI), name, speed, course, etc. Receives similar information from other AIS equipped vessels within VHF range and outputs that

information for use by an external display medium (AIS enabled chart plotter, PC using AIS enabled

chart plotter software etc.)

4. Built-in test

The Nauticast™-B AIS unit is equipped with Built in Integrity Testing (BIIT). BIIT tests run continuously or at appropriate intervals simultaneously with the standard functions of the equipment. The BIIT detects any failure or malfunction that will significantly reduce integrity or stop operation of the Nauticast™-B AIS unit.

The tests include:

AIS TX malfunction (synthesizer not locked and TX time-out not exceeded) Antenna VSWR exceeds limit Rx channel 1 malfunction (synthesizer not locked) Rx channel 2 malfunction (synthesizer not locked) Internal GNSS not in use No valid SOG information No valid COG information Background noise > -77dBm GPS failure VSWR exceeding the maximum allowed level The input voltage is out of the specified range

5. LED indicators

Power

This is a green LED which indicates, when lit, that power has been connected correctly to the transponder, that the transponder hardware has been configured, that the operating software is present, that the CPU has booted up and the application software is running.

Y1-03-0222 Rev. C

TX timeout

This is a yellow LED which indicates when lit that the CSTDMA transmitter is prevented from transmitting. Reasons for this include the following:

The transponder‟s internal GPS receiver is not yet ready. The yellow LED will go out and the green LED

will light when GPS receiver is ready. The transponder was unable to transmit an AIS message due to the channel being already occupied,

e.g. by transmissions from other AIS transponders. Wait 10 minutes and verify GPS antenna

connection. The transponder‟s internal GPS receiver is not operating. Contact your local dealer for service.

Error

This is a red LED which indicates, when lit, one of the following status conditions is possible:

Transmitter lockout timer (1 second maximum) has operated GPS is unable to gain lock after 30 minutes VHF antenna VSWR is out of range Power Supply is out of range Background noise level is above the threshold level (-77dBm) MMSI is not entered

Blue LED

The unit has a blue LED that, when lit, indicates one of the following two conditions depending on how it is programmed:

Safety Related Message (SRM) status

The Safety Related Message (SRM) button (not included, recommend momentary contact switch rated

for > 25mA) has been depressed for more than 2 seconds and the pre-set SRM has been sent. If the

SRM LED is illuminated it is not possible to send another SRM. An SRM can be sent once a minute.

The payload within the message 14 transmission is the text string “MAYDAY MAYDAY”. Silent Mode Function (if user configures SRM switch to act as Silent Mode switch)

This indicates that the Silent Mode button has been depressed for more than 2 seconds and the pre-set

Silent Mode has been activated. If the blue LED is illuminated you are not transmitting your AIS data to

other vessels, your AIS is acting as a receive-only device. Depress the Silent Mode button a second

time transmit your position data.

Both of these functions can be accessed through the Link2AIS™ software when a switch is not installed.

SECTION 4 - MAINTENANCE

WARNING:

CAUTION:

NOTE 2 The sequential message identifier provides a message identification number from 0 to 9 that is

sequentially assigned and is incremented for each new multi-sentence message. The count resets to 0 after 9 is used. For a message requiring multiple sentences, each sentence of the message contains the same sequential message identification number. It is used to identify the sentences containing portions of the same message. This allows for the possibility that other sentences might be interleaved with the message sentences that, taken collectively, contain a single message. This shall be a null field for messages that fit into one sentence.

NOTE 3 The AIS channel is indicated as either “A” or “B”. This channel indication is relative to the operating

conditions of the AIS unit when the packet is received. This shall be a null field when the channel

identification is not provided. The VHF channel numbers for channels “A” and “B” are obtained by using a “query” (See IEC 61162-1, clause 5.3.2) of the AIS unit for an ACA sentence.

6. Regional Assignment Channel Assignment Message (NMEA 0183 ACA)

A Nauticast™-B unit can receive regional channel management information in two ways: ITU-R M.1371 message 22 or a DSC telecommand received on channel 70. Channel management information is applied based upon the actual location of the AIS device. An AIS unit is “using” channel management information when the information is being used to manage the operation of the VHF receiver and/or transmitter inside the AIS unit. This sentence is used both to 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.1371-1 message 22. The information contained in this sentence directly relates to the Initialization Phase and Dual Channel Operation and Channel Management functions of the AIS unit as described in ITU-R M. 1371.
