: Most SARTs can stay in "standby" mode for at least 96 hours and transmit actively for 8 to 12 hours once triggered.
: As the rescue vessel gets closer, the dots on the radar turn into arcs and eventually full circles when the ship is very near the survivors. Key Specifications
: These devices are designed to survive a 20-meter drop into the water and operate in extreme temperatures ranging from -20∘Cnegative 20 raised to the composed with power cap C +55∘Cpositive 55 raised to the composed with power cap C
A is a portable, waterproof device used to help rescue teams locate a ship or life raft in distress. It is a vital part of the Global Maritime Distress and Safety System (GMDSS) . How It Works
: When an X-band radar (9 GHz) from a nearby ship or helicopter hits the SART, it "wakes up" and transmits a signal back.
: On the rescuer's radar screen, the SART signal appears as a distinctive line of 12 dots . These dots point directly to the location of the survivors.
: To get the best signal, survivors should mount the SART as high as possible (ideally at least 1 meter above the water). Search and Rescue Transponder (SART) - Accident Data - NTSB
