NSSDCA/COSPAR ID: 1981-105A
The Molniya-3 Soviet communications satellites were used to create the 'Orbita' communications system for northern regions, with groups of four satellites. The first Molniya 3 spacecraft appeared in 1974, primarily to support civil communications (domestic and international), with a slightly enhanced electrical power system and a communications payload of three 6/4 GHz transponders with power outputs of 40 W or 80 W. The land segment used a 12 m diameter parabolic antenna, which was pointed automatically at the satellite using autonomous electromechanical equipment. Later versions were to be part of the YeSSS Unified Satellite Communications System. Trials of this version began in the 1980's, with the system being accepted by the Russian military in 1983-1985.
