Summary
COSMOS 1540 (also known as Kosmos-1540) is a military relay satellite launched on March 2, 1984, from the TYMSC launch site using a Proton-K/DM launch vehicle. The spacecraft has a cylindrical shape with two panels and a plate configuration, measuring 5.5 meters in length and 2.5 meters in diameter, with a span of 9 meters when its solar arrays are deployed. It was manufactured by NPOPM for GUKOS (Soviet Ministry of Defence) and is powered by two deployable solar arrays and batteries. COSMOS 1540 carries the Geizer No. 12L payload, featuring Slav-2 and Sintez C-band transponders for military communication purposes. The satellite has a dry mass of 1900 kg and a launch mass of 2100 kg, with propulsion provided by four SPT-70 Stationary Plasma Thrusters. Its mission is to serve as a military relay satellite in geostationary orbit (GSO).
