Kosmos 1546 (Russian: Космос 1546 meaning Cosmos 1546) is a Soviet US-KS missile early warning satellite which was launched in 1984 as part of the Oko programme. The satellite is designed to identify missile launches using optical telescopes and infrared sensors.^[1]

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]
