What is an automatic identification system and how does it work?

Automatic Identification System (AIS) is an automated tracking system that displays other vessels in the vicinity. It is a broadcast transponder system which operates in the VHF mobile maritime band. Your own ship also shows on the screens of other vessels in the vicinity, provided your vessel is fitted with AIS.

What is AIS and its use?

The automatic identification system, or AIS, transmits a ship’s position so that other ships are aware of its position. The International Maritime Organization and other management bodies require large ships, including many commercial fishing vessels, to broadcast their position with AIS in order to avoid collisions.

What is an AIS in ship?

Automatic identification systems (AIS) transponders are designed to be capable of providing position, identification and other information about the ship to other ships and to coastal authorities automatically.

What is the working principle of AIS?

Principle. AIS is working on the VHF frequency. The data are transmitted by using STDMA (self-organizing time division multiple access). The STDMA uses the precise timing of the GPS signal to synchronise multiple data transmission from many users on a single narrow band channel.

What is the other name of automatic identification system?

The automatic identification system (AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS). When satellites are used to detect AIS signatures, the term Satellite-AIS (S-AIS) is used.

What are the two types of AIS?

Class A And Class B Automatic Identification System (AIS) AIS information is divided into two classes – classes A and B – depending on the AIS transponder transmitting the AIS information. These classes are of great importance to the capabilities of your AIS.

What is the purpose of Automatic Identification System?

The Automatic Identification System (AIS) is an automated tracking system employed on ships and by Vessel Traffic Services (VTS) for discovering and locating vessels by electronically exchanging data with other nearby ships and VTS stations.

How does AIS work?

AIS works by taking your position and movements via the vessels’ GPS system or an internal sensor built into an AIS unit. That information is then collated along with programmable information from the AIS unit (e.g. Maritime Mobile Service Identity (MMSI) number, vessel name, destination,…

What is Automatic Identification Technology?

Automatic identification ( auto ID ) is a process of automatic data identification via a set of methods, technologies and devices, such as bar code readers, radio frequency identification (RFID), magnetic stripe cards/readers and optical memory cards. These technologies are used for the automatic detection and identification of data objects.
