The AIS-SART is a self contained radio device used to locate a survival craft or distressed vessel by sending updated position reports using a standard Automatic Identification System (AIS) class A position report. The position and time synchronization of the AIS-SART is derived from a built in GNSS receiver (e.g. GPS).[1] Shipboard Global Maritime Distress Safety System (GMDSS) installations include one or more search and rescue locating devices. These devices may be either an AIS-SART (from 1.January 2010) (AIS Search and Rescue Transmitter), or a radar-SART (Search and Rescue Transponder).
The AIS-SART derives position and time synchronization from a built in GNSS receiver and transmits its position with an update rate of 1 minute. Every minute the position is sent as a series of eight identical position reports, this is to maintain a high probability that at least one of the position reports is sent on the highest point of a wave.
AIS SARTs are typically cylindrical, and brightly colored. A typical model is 251mm (about 10 inches) high and weighs 450g (about a pound).
The specification for the AIS-SART has been developed by the IEC (International Electrical Committee), TC80, AIS work group. The AIS SART was added to the GMDSS regulations effective January 1, 2010. [1]
