Kosmos 1217 was launched from Site 41/1 at Plesetsk Cosmodrome in the Russian SSR.[3] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 10:53 UTC on 24 October 1980.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1980-085A.[4] The United States Space Command assigned it the Satellite Catalog Number 12032.[4]
