Which of the following best describes the SART's method of operation?

Transmits continuously on 121.5 MHz

Responds to radar interrogations, typically at 9 GHz

The SART operates as a radar transponder that stays silent until it is interrogated by another ship’s radar. When it receives a radar interrogation, it responds with a radar beacon at around 9 GHz (the X-band), and that response appears on the interrogating radar as a distinctive pattern of dots or a line of dots. This helps rescuers quickly determine the bearing and range to the emergency transmitter, making it easier to locate the vessel in distress. It does not transmit continuously on 121.5 MHz, it is not a satellite distress beacon at 406 MHz, and it does not provide weather updates.

Operates only with distress beacons on 406 MHz

Receives weather updates from satellites
