Kosmos 1546 was launched from Site 200/40 at Baikonur Cosmodrome in the Kazakh SSR.[1] A Proton-K carrier rocket with a DM upper stage was used to perform the launch, which took place at 05:53 UTC on 29 March 1984.[3][4] The launch successfully placed the satellite into geostationary orbit. It subsequently received its Kosmos designation, and the international designator 1984-031A.[3] The United States Space Command assigned it the Satellite Catalog Number 14867.[3][4]
It was operational for about 30 months.[4]
