Kosmos 285 (Russian: Космос 285 meaning Cosmos 285), known before launch as DS-P1-Yu No.24,[1] was a Soviet satellite which was used as a radar calibration target for tests of anti-ballistic missiles. It was a 250-kilogram (550 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and launched in 1969 as part of the Dnepropetrovsk Sputnik programme.[2]

Kosmos 285 was launched from Site 133/1 at the Plesetsk Cosmodrome,[1] atop a Kosmos-2I 63SM carrier rocket. The launch occurred on 3 June 1969 at 12:57:27 UTC, and resulted in Kosmos 285's successful deployment into low Earth orbit.[3] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1969-049A.

Kosmos 285 was operated in an orbit with a perigee of 257 kilometres (160 mi), an apogee of 452 kilometres (281 mi), 71 degrees of inclination, and an orbital period of 91.6 minutes.[2][4] It remained in orbit until it decayed and reentered the atmosphere on 7 October 1969.[4] It was the twenty-second of seventy nine DS-P1-Yu satellites to be launched,[2] and the twenty-first of seventy two to successfully reach orbit.[5]
