Which system detects and relays signals from ELTs, EPIRBs, and PLBs to the RCC?

• A. Sarsat
• B. CospaSat
• C. RescueSat
• D. GlobalSAR

Answer: (A)

The system that detects and relays signals from ELTs, EPIRBs, and PLBs to the RCC is the SARSAT system (Cospas-Sarsat). This international satellite-based network monitors distress beacons and automatically passes their encoded location and ID data to Rescue Coordination Centers. Beacons transmit on 406 MHz (with a unique ID) and, when needed, older beacons may also use 121.5/243 MHz for homing. Satellites pick up the signal and route it through ground stations and Mission Control Centers to the appropriate RCC, which then coordinates search and rescue. The other names listed aren’t the recognized system names; one is a misspelling of the actual network, and the others aren’t the system used for beacon detection and relay.
