Kosmos 526 (Russian: Космос 526 meaning Cosmos 526), known before launch as DS-P1-Yu No.61, was a Soviet satellite which was launched in 1972 as part of the Dnepropetrovsk Sputnik programme. It was a 325-kilogram (717 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 526 was successfully launched into low Earth orbit at 10:39:57 UTC on 25 October 1972.[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 1972-084A.[4] The North American Aerospace Defense Command assigned it the catalogue number 06254.

Kosmos 526 was the fifty-ninth of seventy nine DS-P1-Yu satellites to be launched,[1] and the fifty-third of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of 264 kilometres (164 mi), an apogee of 461 kilometres (286 mi), 70.9 degrees of inclination, and an orbital period of 91.8 minutes.[6] It remained in orbit until it decayed and reentered the atmosphere on 8 April 1973.[6]
