Summary
The COSMOS 2140 [GLONASS] satellite, also known as Kosmos-2140, was launched on April 4, 1991, from the Tyuratam Space Center (TYMSC) using a Proton-K/DM-2 launch vehicle. The spacecraft is part of the Uragan series and has a 3-axis stabilized configuration. It measures 4 meters in length, with a diameter of 1.5 meters and a span of 7.8 meters when its solar arrays are deployed. The satellite's dry mass is 1200 kg, and it had an initial launch mass of 1300 kg. Equipped with two deployable solar arrays and batteries for power supply, the satellite was designed to serve navigation purposes as part of the GLONASS constellation. Launched by the Soviet Union (SU), its manufacturer is POL, though specific details about its payload are not provided. The mission was intended to last for approximately 3 years.
