AKA: 17F15;Globus. Status: Operational 1989. First Launch: 1989-06-21. Last Launch: 2013-11-11. Number: 11 . Gross mass: 2,000 kg (4,400 lb).
Phase 1 of the system was to have consisted of three Raduga-1 spacecraft. The Raduga-1 was capable of communication not just with fixed earth stations, but mobile platforms as well. It was equipped with the Tor C-band transponder, working at 20, 42, and 44 GHz. Although a later generation system, Raduga-1 still used the KAUR-3 spacecraft bus. This was 3-axis stabilized using liquid propellant micro-engines to within 0.25 degrees of the earth's center. The single-unit body was equipped with solar panels, and active liquid-gas phase-change thermoregulation system, and a corrective engine unit for making orbital adjustments. 25 square meters of solar panels provided 1280 W of power.
