Kosmos 705

Kosmos 705 (Космос 705 meaning Cosmos 705), also known as DS-P1-Yu No.75, was a Soviet satellite which was launched in 1975 as part of the Dnepropetrovsk Sputnik programme. It was a 400 kg spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.

A Kosmos-2I 63SM carrier rocket was used to launch Kosmos 705 from Site 133/1 of the Plesetsk Cosmodrome. The launch occurred at 12:05:01 UTC on 28 January 1975, and resulted in the satellite successfully reaching low Earth orbit. Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1975-006A. The North American Aerospace Defense Command assigned it the catalogue number 07623.

Kosmos 705 was the seventy-fifth of seventy nine DS-P1-Yu satellites to be launched, and the sixty-eighth of seventy two to successfully reach orbit. It was operated in an orbit with a perigee of 268 km, an apogee of 484 km, 70.9 degrees of inclination, and an orbital period of 92.1 minutes. It remained in orbit until it decayed and reentered the atmosphere on 18 November 1975.
