Kosmos 319 (Russian: Космос 319 meaning Cosmos 319), known before launch as DS-P1-Yu #25, was a Soviet satellite which was 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 319 was launched from Site 133/1 at the Plesetsk Cosmodrome,[2] atop a Kosmos-2I 63SM carrier rocket. The launch occurred on 15 January 1970 at 13:39:59 GMT, and resulted in the successful deployment of Kosmos 319 into low Earth orbit.[3] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1970-004A.
Kosmos 319 was operated in an orbit with a perigee of 196 kilometres (122 mi), an apogee of 1,371 kilometres (852 mi), 81.9 degrees of inclination, and an orbital period of 100.5 minutes.[1][4] It remained in orbit until it decayed and reentered the atmosphere on 1 July 1970.[4] It was the twenty-ninth of seventy nine DS-P1-Yu satellites to be launched,[1] and the twenty-seventh of seventy two to successfully reach orbit.[5]
