Satellite system COSPAS - SARSAT
The international satellite system COSPAS-SARSAT is one of the main parts of the GMDSS and is designed to detect and locate ships, airplanes, and other objects that have crashed.
The COSPAS-SARSAT system consists of the following main complexes:
1) emergency radio beacons ARB (EPIRB), which transmit signals in an emergency;
2) equipment onboard geostationary and low-orbit satellites, which allows detection of signals transmitted by emergency radio beacons;
3) ground receiving stations that receive and process signals from satellites to generate alarm messages;
4) system focal points that receive emergency messages and send them to rescue coordinating centers (SCC).
