The difference between SART and AIS SART – SARTs (Search and Rescue Transponders) are the primary means of identifying ships in distress or their survival craft in the GMDSS, and their carriage on board ships is required. The SART is a compact omnidirectional radar receiver and transmitter that runs on batteries. They could also be used in a satellite EPIRB that does not float. A SART’s batteries allow it to operate in standby mode for at least 96 hours, plus an additional 8 hours when being interrogated.
Difference between Radar SART and AIS SART:
Radar SART would wait for a passing vessel to send a RADAR signal before emitting a sequence of RADAR pulses. On the ship’s RADAR display, the SART would appear as a series of RADAR returns leading to the SART’s location.
An AIS SART sends out AIS messages with precise GPS location data. Any vessel equipped with AIS can receive these messages, which can trigger an alarm tied to the specific location of the SART AIS.
What is the difference between AIS Sart and Radar Sart?
An AIS-SART (Automatic Identification System Search and Rescue Transmitter) is used in marine environments to aid in the rescue of people in distress, while a Radar-SART (Search and Rescue Transponder) is used to locate and rescue vessels in distress by providing a radar signal that can be detected by other ships or aircraft. AIS-SART is more commonly used for man-overboard situations, while Radar-SART is used for emergency situations involving vessels.
