1 General Introduction

Y1-03-0183-1 Rev. A

1.1 Description of AIS

What does the abbreviation AIS stand for?

AIS stands for: “Automatic Identification System”

What is AIS?

According to IALA regulations, AIS is defined as follows:

Very simply, the 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 Self-Organizing Time Division Multiple Access (SOTDMA) technology to meet these high broadcast rates and ensure reliable and robust ship to ship operation.

What are the performance standards of AIS?

The IMO defines the performance standards as follows:

Which modules make up an AIS-Transponder?

The Modules:

Appropriate application software connects the individual modules.

In which modes does AIS function?

AIS is required to function flawlessly in a variety of modes. The relevant regulations require:

The system shall be capable of

- Ship to Ship working

- Ship to Shore working, including Long Range Application

- Automatic and continuous operation

- Provision of information messaging

- Utilization of maritime VHF channels

- GPS receiver

- VHF Radio

- Antenna

- Computer (CPU)

- Power Supply

- 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.

3.3 Installation of VHF / GPS Antennas

Interference to the Ship’s VHF Radiotelephone

The AIS ship borne equipment, like any other ship borne transceiver operating in the VHF maritime band, may cause interference to a ship’s VHF radiotelephone. Because AIS is a digital system, this interference may occur as a periodic (e.g. every 20 seconds) soft clicking sound on the ship’s radiotelephone. This affect may become more noticeable if the VHF radiotelephone antenna is located close to the AIS VHF antenna, and when the radiotelephone is operating on channels near the AIS operating channels (e.g. channels 27, 28 and 86).

Attention should be paid to the location and installation of the various antennas, in order to support the antenna characteristics in the best possible way.

VHF Antenna Installation

Antenna Location

Location of the mandatory AIS VHF-antenna should be carefully considered. Digital communication is more sensitive than analogue/voice communication to interference created by reflections caused by obstructions such as masts and booms. It may be necessary to relocate the VHF radiotelephone antenna to minimize interference effects.

To minimise interference effects, the following guidelines apply:

• The AIS VHF antenna should have omni directional vertical polarisation providing 3 to 5 dB gain.

• The AIS VHF antenna should be placed in an elevated position, as free standing as possible, 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. The AIS VHF antenna should have a visible sky of 360°.

• The AIS VHF antenna should be installed at least 3 meters away from interfering highpower energy sources such as radar and other transmitting radio antennas, and out of the way of the transmitting beam.

• There should not be more than one antenna on each level. The AIS VHF antenna should be mounted directly above or below the ship’s primary VHF radiotelephone antenna, with no horizontal separation and a minimum of 2 metres vertical separation. If it is located on the same level as other antennas, the distance apart should measure at least 10 metres.

See also sample for antenna layout in the Appendix.

Cabling

The cable should be kept as short as possible to minimise attenuation of the signal. Double shielded coaxial cables equal to or better than RG214 are recommended. RG214 at VHF attenuation per meter of app. 0,07 dB/m (45m = 3,15db) VHF AIS frequency app. 162MHz

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

GlobalWatch

AIS Installation Manual 6 Version 1.0

Coaxial cables should be installed in separate signal cable channels/tubes, and at least 10

Y1-03-0183-1 Rev. A

cm away from any power supply cables. Crossing of cables should take place at right angles (90°). Coaxial cables should not be exposed to sharp bends, which may lead to changes to the characteristic impedance of the cable. The minimum bend radius should be 5 times the cables outside diameter.

Grounding

Coaxial down-leads must be used for all receiving antennas, and the coaxial screen should be connected to the ground at one end.

GNSS Antenna installation

A Class A AIS must be connected to a GNSS antenna.

Location

The GNSS antenna must be installed where it has a clear view of the sky, so that it accesses the horizon freely through 360°, with a vertical observation of 5 to 90 degrees above the horizon. Small diameter obstructions, such as masts and booms, do not seriously impair signal reception, but such objects must not eclipse more than a few degrees of any given bearing.

The antenna must be located at least three 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 designed and installed separately.

Cabling

To achieve optimum performance, the gain of the antenna pre-amplifier should match the cable attenuation. The resulting installation gain (pre-amplifier gain - cable attenuation) should be within 0 to 10 dB. RG214 at GPS attenuation per meter of app. 0,35 dB/m (45m = 15,75dB) GPS frequency app. 1,2GHz

The coaxial cable between the antenna and the AIS ship borne station connector should be routed directly, in order to reduce electromagnetic interference. The cable should not be installed close to high-power lines, such as radar or radio-transmitter lines, or near the AIS VHF antenna cable. A space of one meter or more is recommended in order to avoid degradation due to RF-coupling. Crossing of antenna cables should take place at 90 degrees, to minimise magnetic field coupling.

Antenna Layout

The position of the VHF und GNSS – antennas must be added to the existing antenna layout of the vessel.

4.2 Service and User Passwords:

Y1-03-0183-1 Rev. A

The Transponder system is equipped with two separate Passwords.

1) The User Password, which is the lower security level allows access to all menus except

Menu 6: Service Configuration - please refer to the User Manual for further details on password protection.

2) The Service Password is required in order to enter the Service Configuration Menu. This is

a higher security level than can be accessed with the User Password and therefore ensures that the Service Configuration is protected, and limited to authorized service personnel. The master of the vessel has to ensure that only authorised persons are allowed to make changes to the Service Configuration and ensures that the newly reset password is stored very carefully, as it can not be reset from the default “NAUT” a second time. A master key is not available.

Changing the Service Password

Select “Service Configuration” from the Main Menu with the cursor button [Up] & [Down] or press Nr. 6 on the keyboard.
