A.I.S. SART - SOLAS Certified

Automatic Identification System Search And Rescue Transponder

Why choose AIS SART over Radar SART?

Traditionally SARTs were based on RADAR technology. When the SART was activated it would wait until a RADAR signal from a passing vessel was received, then emit a series of RADAR pulses. The SART would appear as a series of RADAR returns on the ships RADAR display leading to the SARTs location.

An AIS SART does not use RADAR technology, instead it transmits AIS messages containing accurate GPS position information. These messages can be received by any vessel with AIS and can generate an alarm linked to the exact location of the SART. AIS and RADAR SARTs are considered equivalent by maritime authorities.
