What is Cospas-Sarsat? ? ? COSPAS = Cosmicheskaya Systyema Poiska Aariynyich Sudov Which loosely translates into: “The Space System for the Search of Vessels in Distress” SARSAT = Search And Rescue Satellite Aided Tracking In short, Cospas-Sarsat takes the “search” out of Search & Rescue
Rescues In 2001: ü 1, 545 persons rescued in 365 SAR events - 1341 maritime rescues in 239 SAR events - 83 aviation rescues in 47 SAR events - 121 land rescues in 79 SAR events Since 1982 over 14, 000 lives rescued via Cospas. Sarsat! Nearly 5, 000 in U. S. AOR’s alone!
Rescues in 2001
Emergency Beacons • Two types: 121. 5/243 MHz and 406 MHz • Three applications: - Emergency Position Indication Radio Beacons (EPIRB) - Emergency Locator Transmitters (ELT) - Personal Locator Beacons (PLB)
121. 5 MHz Beacons • Older technology • Not designed for satellite processing (no store & forward capability) • Analog signal only = no identification code • Does not have global coverage! • Low power ( < 1 watt) • Less rigid standards • Poor location accuracy = Usually no better than 12 miles • USMCC handles 400 -600 ‘hits’ per day. 99. 5% are false!! Will Not Be Detected by Satellites After February 1, 2009!
243 MHz Beacons • Similar to 121. 5 MHz beacons • Primarily used by the military • Many existing 121. 5 MHz also transmit on 243 MHz • Will Not Be Detected by Satellites After February 1, 2009!
406 MHz Beacons • Newer technology • Designed for satellite processing (store & forward) • Global coverage • Digital signal • Increased power (5 watt) • Unique Identification • Rigid specifications • More Accurate = 2 - 3 mile location accuracy. Even better with integral GPS units = 100 meter accuracy!
Beacons with Navigation Input • Improved accuracy • Instantaneous detection 406 MHz with GPS 406 MHz 121. 5 MHz
Space Segment • Two types of satellites • Low-Earth Orbiting Search and Rescue (LEOSAR) • Geostationary Orbiting Search and Rescue (GEOSAR)
2 Types of Satellites: • Space Segment Low Earth Orbiting Search And Rescue (LEOSAR) (8) Satellites in Orbit: • - COSPAS 4, 9, 10 - SARSAT 4, 6, 7, 8, 9 Geostationary Orbiting Search And Rescue (GEOSAR) (4) Satellites in Orbit: - GOES 8, 10 - INSAT 2 B - MSG (recently launched & undergoing testing)
Satellite 406 MHz beacon detections can be stored on board the satellite and re-broadcast later LUT 121. 5/243 MHz Beacon Detection of a 121. 5/243 MHz beacon requires mutual visibility between beacon, satellite and ground station (LUT) Satellite LUT 406 MHz Beacon

International Organization • Initially developed under interagency Memorandum of Agreement signed in 1979 • International Cospas-Sarsat Programme Agreement signed on July 1, 1988 among the governments of Canada, France, the former U. S. S. R and the United States • Association with Programme allows States to contribute towards the ground segment or participate in international Cospas-Sarsat meetings • Goals of Cospas-Sarsat are to support SAR objectives of ICAO and IMO
