AIS class B transponders supplied from F&C Marine.

The AIS Class B automatic identification system (AIS) is an automatic tracking system that uses transponders 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. AIS information supplements marine radar, which continues to be the primary method of collision avoidance for water transport.[citation needed]

Information provided by AIS equipment

  • unique identification
  • position
  • course and speed

The data is displayed on a screen or can be interfaced to other equipment such as an ECDIS or Radar.

AIS is intended to assist a vessel’s watchstanding officers/crew members and allows maritime authorities to track and monitor each vessels movements.  AIS integrates a standardized VHF transceiver with a positioning system such as a GPS receiver, with other electronic navigation sensors, such as a compass or rate of turn indicators. Vessels fitted with AIS transceivers can be tracked by AIS base stations located along spaced out coast lines or, when out of range of terrestrial networks, through a growing number of satellites that are fitted with special AIS receivers.
