The worldwide satellite system for search and rescue has been in operation since 1982 and has assisted in the rescue of thousands of lives in distress. Aviators, mariners and land users being equipped with distress beacons are capable of transmitting distress signals to the satellites in emergency situations anywhere in the world. This paper describes the configuration of the search and rescue satellite system, principles of its operation, and how the system is utilized to process the distress events. Also, this paper points out the importance of development of technologies of user equipment and proposes an experimental program for technology development using domestic satellites.
