Launch

The launch of Kosmos 369 took place from Site 133/1 at the Plesetsk Cosmodrome,[2] and used a Kosmos-2I 63SM carrier rocket. The launch occurred at 15:10:03 UTC on 8 October 1970, and successfully deployed Kosmos 369 into low Earth orbit.[3] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1970-081A.[4]

Orbit

Kosmos 369 was the thirty-sixth of seventy nine DS-P1-Yu satellites to be launched,[1] and the thirty-third 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 454 kilometres (282 mi), 70.9 degrees of inclination, and an orbital period of 91.6 minutes.[1][6] It remained in orbit until it decayed and reentered the atmosphere on 22 January 1971.[6]
