Summary
COSMOS 1888, also known as Kosmos-1888, is a military relay satellite launched on October 1, 1987, from the TYSMC launch site using the Proton-K/DM-2 launch vehicle. Manufactured by NPOPM/NPOL, it has a configuration of MSS-2500-GSO and carries the Geizer No. 15L payload. The satellite measures 5.5 meters in length with a diameter of 2.5 meters and spans 9 meters when its components are deployed. It weighs 1900 kg dry, with a launch mass of 2100 kg. Equipped with Slav-2 and Sintez C-band transponders for communication, COSMOS 1888 uses four SPT-70 Stationary Plasma Thrusters for propulsion and is powered by two deployable solar arrays complemented by batteries. Its structure consists of a cylindrical body with two panels and a plate, giving it a radar cross-section of 6.3095 square meters. The satellite was deployed into geostationary orbit to serve military relay purposes.
