US-P

US-P

US-P (Upravlenniye Sputnik Passivny) was a solar powered EORSAT (Electronic Ocean Reconnaissance Satellite). It used an passive ELINT devices to track naval vessels from space by registering their electronic emmissions.

The soviet satellite systems to monitor foreign fleet movements split into two families, the passive US-P program and the active radar equipped satellites designated US-A which carried nuclear reactors.

Both types shared the same US bus, which provided maneuvering capabilities to the spacecraft. As the passive detection systems did not need as much power as the active radar system of the US-A, it was fitted with solar arrays.

The US-P were placed into a 420 km orbits inclined 65 degrees by the Tsiklon-2 booster. Systems aboard the 3300 kg satellite included the Radio-Technical Reconnaissance system and systems for electronic camouflage and self-protection. An engine unit maintained the orbital altitude and made a final deorbit of the satellite at the end of the mission.
