From 1982 several Tsikada maritime navigation satellites were equipped with the supplemental COSPAS / SARSAT international space search and rescue system for locating vessels and aircraft in distress search and rescue package. These were designated 'Nadezhda'. 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).

Total Mass: 820 kg.

Trials of experimental equipment for testing systems to determine the location of vessels and aircraft in distress.

Carried COSPAS transponder; replaced Cosmos 1226. Investigation of the upper atmosphere and outer space; testing of systems for locating the position of ships and aircraft in difficulties (COSPAS-SARSAT system).
