Kosmos 36 (Russian: Космос 36 meaning Cosmos 36), also known as DS-P1-Yu #1 was a satellite which was used for use in calibrating the Dnestr space surveillance and as a radar calibration target, for tests of anti-ballistic missiles.

[3] It was launched by the Soviet Union in 1964 as part of the Dnepropetrovsk Sputnik programme.

Kosmos 36 was launched using a Kosmos-2I 63S1 carrier rocket,[4] which flew from Mayak-2 at Kapustin Yar.

[5] After separating from its carrier rocket, Kosmos 36 was in a low Earth orbit with a perigee of 261 kilometres (162 mi), an apogee of 477 kilometres (296 mi), 49.0° of inclination, and an orbital period of 91.9 minutes.

The next launch of a DS-P1-Yu satellite, the DS-P1-Yu #2 will be on 12 February 1965, failed due to a second stage malfunction.
