The Search and Rescue Satellite Aided Tracking (SARSAT) System detects and locates mariners, aviators, hikers and mountaineers in distress. The SARSAT system uses NOAA satellites in low-Earth and geostationary orbits to detect and locate emergency beacon transmissions. The satellites relay these distress signals to a network of ground stations and ultimately to the U.S. Mission Control Center, which alerts the appropriate local search and rescue authorities.
