Kosmos 307 (Russian: Космос 307 meaning Cosmos 307), known before launch as DS-P1-Yu No.22, was a Soviet satellite launched in 1969 as part of the Dnepropetrovsk Sputnik programme. It was a 250-kilogram (550 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.[1]
Kosmos 307 was launched from Site 86/4atKapustin Yar,[2] atop a Kosmos-2I 63SM carrier rocket. The launch occurred on 24 October 1969 at 13:01:58 UTC, and resulted in the successful deployment of Kosmos 307 into low Earth orbit.[3] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1969-094A.
Kosmos 307 was operated in an orbit with a perigee of 212 kilometres (132 mi), an apogee of 2,023 kilometres (1,257 mi), 48.4 degrees of inclination, and an orbital period of 107.7 minutes.[1][4] It remained in orbit until it decayed and reentered the atmosphere on 30 December 1970.[4] It was the twenty-sixth of seventy nine DS-P1-Yu satellites to be launched,[1] and the twenty-fourth of seventy two to successfully reach orbit.[5]
