Article Number: 17F118. Class: Navigation. Destination: Medium Earth Orbit. Nation: Ukraine. Agency: MO SSSR. Manufacturer: Yuzhnoye. On 6 May 1977 the USSR and US signed the COSPAS-SPASAT Treaty covering deployment of an international system of emergency beacon receivers aboard satellites. On 23 November 1979 a Memorandum of Agreement was signed by the USA, USSR, Canada, and France on implementation of the system. The receivers would be placed on satellites operating below 1,000 km altitude, and provide a positional accuracy of 3 km for 406 MHz beacons, 20 km for 121.5 MHz. Twenty were flown aboard Tsikada maritime navigation satellites, the first being Kosmos 1383 on 30 June 1982. The system, designated 'Nadezhda', was credited with saving hundreds of lives. From 1995 these satellites were equipped with the Kurs system for better location of air, sea, and ground craft in distress and for transmittal of digital data to the Kurs Centre. These were designated Nadezhda-M. Signals at 150,00 MHz and 400.00 MHz. The spacecraft provided dual use - location of vessels in the Soviet merchant marine and fishing fleet; and work within the international space search and rescue system for locating vessels and aircraft in distress (COSPAS-SARSAT). Typical orbit: 952 km x 1012 km at 83 degrees inclination. Mass: 820 kg (1,800 lb). Associated Launch Vehicle: Kosmos 11K65M.
