AIS-SART

An 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 are derived from a built in GNSS receiver (e.g.

[1] Shipboard Global Maritime Distress Safety System (GMDSS) installations include one or more search and rescue locating devices.

The AIS-SART derives position and time synchronization from a built in GNSS receiver.

This scheme creates a high probability that at least one of the messages is sent on the highest point of a wave.
