Kosmos 116

Kosmos 116 (Космос 116 meaning Cosmos 116), also known as DS-P1-Yu No.6 was a Soviet satellite which was used as a radar calibration target for tests of anti-ballistic missiles. It was built by the Yuzhnoye Design Bureau, and launched in 1966 as part of the Dnepropetrovsk Sputnik programme.

Kosmos 116 was launched using a Kosmos-2M 63S1M carrier rocket, which flew from Site 86/1 at Kapustin Yar. The launch occurred at 10:04 GMT on 26 April 1966, and was successful. Kosmos 116 separated from its carrier rocket into a low Earth orbit with a perigee of 289 km, an apogee of 451 km, an inclination of 48.4°, and an orbital period of 92.0 minutes. It decayed from orbit on 3 December 1966. Kosmos 116 was the fifth of seventy nine DS-P1-Yu satellites to be launched, and the fourth of seventy two to successfully reach orbit.
