1 General Introduction
Y1-03-0177A
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:
- 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
Which modules make up an AIS-Transponder?
The Modules:
- DGPS / GPS receiver
- VHF Radio
- Antenna
- Computer (CPU)
- Power Supply
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
- An "autonomous and continuous" mode for operation in all areas. This mode
- An "assigned" mode for operation in an area subject to a competent authority
- A "polling or controlled" mode, where the data transfer occurs in response to
shall be capable of being switched to/from one of the following alternate modes by a competent authority;
responsible for traffic monitoring such that the data transmission interval and/or time slots may be set remotely by that authority;
interrogation from a ship or competent authority.

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 a GlobalWatch
TM
UAIS (or any other certified AIS-Transponder). 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 “Self Organized Time Division Multiple Access”) to send and receive messages.
Without the necessity of any active 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 derivates and complete shore infrastructure).
The Carriage Requirement currently applies exclusively to SOLAS Vessels, but following the current international discussions on maritime security; it is common understanding that other possible AIS users will follow very soon. Shore Based infrastructure will be among the first groups to become AIS equipped.

1.4 Carriage Requirement
Y1-03-0177A
1.4.1 Chapter V (Safety of Navigation) Regulation 19, of the SOLAS Convention.
IMO regulations require sea vessels from a size of 300 GT in international and 500 GT in national waters to be equipped with an AIS-Transponder. The implementation of this legislation began on 1. July 2002 and will be enforced in the following stages:
July 2002 for all vessels built from this period onwards
July 2003 for all passenger ships and all tankers which were built before 1. July 2002
July 2004 for all ships of 50.000 GT and above which were built before 1. July 2002
July 2005 for all ships from 10.000 GT up to under 50.000 which were built before
1. July 2002
July 2006 for all ships from 3.000 GT up to under 10,000 which were built before
1. July 2002
July 2007 for all ships from 300 GT up to under 3.000 which were built before
1. July 2002
July 2008 for all other ships which do not travel in international waters and were built
before July 2002
In some cases, exemptions may be granted to such ships, which will be taken off sea within 2 years of legislation coming into effect.
Refer to IMO Recommendation ITU-R M.1371-1 and IALA-AIS-Guidelines
1.4.2 Accelerated Implementation of AIS:
ANNEX AMENDMENTS TO THE TO THE INTERNATIONAL CONVENTION FOR THE SAFETY OF LIFE AT SEA, 1974 AS AMENDED CHAPTER V - SAFETY OF NAVIGATION
Regulation 19 - Carriage requirements for ship borne navigational Systems and equipment states:
1 The existing subparagraphs .4, .5 and .6 of paragraph 2.4.2 are replaced by the following:
“4 in the case of ships, other than passenger ships and tankers, of 300 gross tonnage and upwards, but less than 50.000 gross tonnage, not later than the first safety equipment survey' after 1 July 2004 or by 31 December 2004, whichever occurs earlier; and”
2 The following new sentence has been added at the end of the existing subparagraph
7 of paragraph 2.4;
“Ships fitted with AIS shall maintain AIS in operation at all times except where international agreements, rules or standards provide for the protection of navigational information.”

The used sentence Formatters are the same as before described at the ECDIS Port.
Note: A pilot input/output port is part of an AIS Class A station. A plug connected to this port should be installed on the bridge near the pilot’s operating position so that a pilot can connect a Personal Pilot Unit (PPU) if required. Also a power connector for the Pilot Unit should be available nearby.
The pilot plug should be configured as follows: (Refer to SUB-COMMITTEE ON SAFETY OF NAVIGATION NAV48/18 2.4.2002)
• AMP/Receptacle (Square Flanged (-1) or Free-Hanging (-2)), Shell size 11, 9-pin, Std. Sex 206486-1/2 or equivalent with the following terminations:
- Tx A (out-) is connected to Pin 1

3.5 Sensor notes
Y1-03-0177A
External Sensor
The AIS has interfaces (configurable as IEC 61162-1 or 61162-2) for position, bottom track (BT) speed, heading and rate of turn (ROT) sensors. In general, sensors installed in compliance with other carriage requirements of SOLAS Chapter V should be connected to the AIS System.*1. The sensor information transmitted by AIS should be the same information being used for navigation of the ship. Interfacing problems might occur if the existing on board sensors do not have serial (IEC 61162) outputs. A converter is needed to translate the non conform data to IEC 61162 – sensor data. For Example Raytheon Nav Data Repeater 133-812
*1)
The fact that AIS is fitted on board a vessel does NOT entail the need to install additional sensors
other that those stated in the carriage requirements.
External GPS
GNSS position sensors normally have IEC 61162 outputs suitable for direct AIS interfacing. However, it is important to note that:
• The Geodetic Datum of the position data is transmitted by the sensor in WGS84 so that an IEC 61162 DTM sentence is configured.
• AIS is able to process two reference points for it’s antenna position, one for external, and one for an internal sensor. If more than one external reference point is used, the appropriate information needs to be input to the AIS, so that the reference point information is suitably adjusted.
External Heading
A gyrocompass providing heading information is a mandatory sensor input to the AIS. A converter unit (synchro or step-signal converter to NMEA 0183 v.3.0 for example Raytheon converter type: 133-812) will be needed for AIS connection in the case that the ship’s gyrocompass does not provide IEC 61162 output.
External Speed and Course
If a bottom track (BT)-log for speed over the ground (SOG) is available, it may be connected. A converter (for example Raytheon converter type: 133-812) is needed if the BT-log does not provide IEC 61162 outputs
External Rate of Turn
Not all ships will carry a Rate-Of-Turn (ROT) indicator according to IMO A.526. However, if a rate-of-turn indicator is available and it includes an IEC 61162 interface, it should be connected to the AIS. If ROT information is not available from a ROT indicator, it may (optionally) be derived from heading information through:
• The gyrocompass itself,
• An external converter unit (see Heading),
• The AIS itself (calculated ROT).

3.6.1 Signal state definitions
The idle, marking, logical 1, OFF or stop bit state is defined by a negative voltage on line A with respect to line B, as in IEC 61162-1. The active, spacing, logical 0, ON or start bit state is defined by a positive voltage on line A with respect to line B, as in IEC 61162-1.
3.6.2 Talker drive circuits
The drive circuit meets the requirements of ITU-T V.11. The maximum output current is I
= 50mA on each port.
max
3.6.3 Listener receive circuits
Multiple listeners may be connected to a single talker. The listener's receive circuit complies with ITU-T V.11. Optional termination resistors (120Ohm) for the Input-lines are provided in the Connection Box. The input terminals A, B and C are electrically isolated from the remaining electronics of the listening device. The input impedance is 30kOhm between A and B lines without the termination resistors. The minimum input voltage is ±0,3V.
3.6.4 Electrical isolation
Within a listener there are no direct electrical connection between the signal lines A and B, the signal ground C or the shield to ship's mains ground or power line. This isolation is in accordance with IEC 60945.
3.6.5 Maximum voltage on the bus
The maximum applied voltage between signal lines A and B and between either line and ground C is in accordance with ITU-T V.11. For protection against miswiring and for unintended connection to earlier TALKER designs, all receive circuit devices are capable of withstanding 15 V between both lines and signal ground for an indefinite period.
3.6.6 Data transmission
Data is transmitted in serial asynchronous form in accordance with 1.2. The first bit is a start bit and is followed by data bits, least-significant-bit first. The following parameters are used: – baud rate 38 400 (bits/s) resp. 4 800 (bits/s) – data bits 8 (D7 = 0), parity none; – stop bits 1.
