Kosmos 634 (Russian: Космос 634 meaning Cosmos 634), also known as DS-P1-Yu No.67, was a Soviet satellite which was launched in 1974 as part of the Dnepropetrovsk Sputnik programme. It was a 400-kilogram (880 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.[1]
The launch of Kosmos 634 took place from Site 133/1 at the Plesetsk Cosmodrome,[2] and used a Kosmos-2I 63SM carrier rocket. It occurred at 16:05 UTC on 5 March 1974, and resulted in the satellite successfully reaching low Earth orbit.[3] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1974-012A.[4] The North American Aerospace Defense Command assigned it the catalogue number 07211.
Kosmos 634 was the sixty-ninth of seventy nine DS-P1-Yu satellites to be launched,[1] and the sixty-third of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of 266 kilometres (165 mi), an apogee of 464 kilometres (288 mi), 70.9 degrees of inclination, and an orbital period of 91.9 minutes.[6] It remained in orbit until it decayed and reentered the atmosphere on 9 October 1974.[6]
