Search and Rescue Transponders (970yyzzzz)

SART Search and rescue transponders.

A search and rescue transponder (SART) is a self-contained, waterproof transponder intended for emergency use at sea.

Search and Rescue Transponders SART's provide a homing signal by transmitting a coded response to a radar signal.

The vessels are equipped with VHF communication, search and rescue transponder and GPS, along with other navigation and communication equipment.

Search and Rescue Transponder (SART) SARTs are portable radar transponders used to help locate survivors of distressed vessels that have sent a distress alert.

DND Optimized Radar Receiver for SART The objective of the project was to investigate approaches for improving the range at which search and rescue transponders can be detected.

Modern lifeboats carry an Emergency Position-Indicating Radio Beacon (EPIRB) and either a radar reflector or Search and Rescue Transponder (SART).

Search and Rescue Radar Transponder (SART) Search and Rescue Transponders (SARTs) are designed to help locate vessels in distress or survivors in a life raft.

The attached guidelines on the operation of marine radar for Search and Rescue Transponders (SART) detection have been prepared by the IMO Sub-Committee on the Safety of Navigation.

The fitting of a 9 GHz radar will permit ships to locate search and rescue transponders (SARTs) required by the Global Maritime Distress and Safety System (GMDSS).

Safety equipment includes Emergency Position-Indicating Radio Beacons, a NAVTEX unit, INMARSAT consoles, various radios, Search and Rescue Transponders, and Digital Selective Calling systems.

Implementation The search and rescue transponder on Galileo satellites detects the distress alert from any Cospas-Sarsat beacon emitting an alert in the 406-406,1 MHz band, and broadcasts this information to dedicated ground stations in the ‘L6’ band.

A Search and Rescue Transponder (SART) may be triggered by any X-Band (3 cm) radar within a range of approximately 8 n.miles. Each radar pulse received causes it to transmit a response which is swept repetitively across the complete radar frequency band.
