Molniya-1T (11F658T)

Molniya-1T [ISS Reshetnev]

The Molniya were Soviet communication satellites operating from an inclined highly elliptical earth orbit of 500 km × 40000 km with 12 hour period for coverage of high northern latitudes.

The Molniya satellites feature a unique configuration. The pressurized, three-axis stabilized KAUR-2 satellite bus features six non-articulated solar arrays and is operated in a sun-pointed mode. The antennas are mounted on two telescopic arms and are pointable. Each antenna features an optical tracking system which provides information to direct one of the two antennas to the Earth.

The KAUR-2 bus features the KDU-414A propellant system with the 5.114 engine.

Molniya-1T for the military telecommunications network Korund carries the Teta communications payload consisting of 5 transponders. It uses wave tubes more reliable than those of Molniya-1K's Beta, which increases the design life of the satellite from two to three years.

Several satellites, beginning with Molniya-1 3, carried an additional earth observation payload called Berkut consisting of two TV cameras, initially black and white, later also colour. This payload was used for meteorology and also for preparation of a early warning system.
