Kosmos 545 (Russian: Космос 545 meaning Cosmos 545), known before launch as DS-P1-Yu No.62, was a Soviet satellite which was launched in 1973 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]
Kosmos 545 was successfully launched into low Earth orbit at 11:44:50 UTC on 24 January 1973.[2] The launch took place from Site 133/1 at the Plesetsk Cosmodrome,[3] and used a Kosmos-2I 63SM carrier rocket.
Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1973-004A.[4] The North American Aerospace Defense Command assigned it the catalogue number 06348.
Kosmos 545 was the sixtieth of seventy nine DS-P1-Yu satellites to be launched,[1] and the fifty-fourth of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of 256 kilometres (159 mi), an apogee of 477 kilometres (296 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 31 July 1973.[6]
