- AIS-SART
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 [http://en.wikipedia.org/wiki/Search_and_Rescue_Transponder] (Search and Rescue Transponder).The AIS-SART is used to locate a survival craft or distressed vessel by sending updated position reports using a standard AIS class A position report. The position and time synchronization of the AIS-SART is derived from a built in GNSS [http://en.wikipedia.org/wiki/Gnss] receiver.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 [8] equal 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.
SARTs are typically cylindrical, and brightly colored.
The specification for the AIS-SART are currently being developed by the AIS work group in IEC, TC80.A draft specification is planned to be published in the 4.quarter of 2008.
