COSMOS 2087, 20707

Orbit data source: Space-Track

COSMOS 2087, 20707 is a payload satellite owned by PVO (CIS) in HEO that was launched on Wed, 25 Jul 1990 UTC via an MOLNIYA 8K78M-PVB launch vehicle from the Plesetsk Missile And Space Complex (PKMTR). Payload-class satellites include a variety of spacecraft equipped with specific instruments for various scientific and technological missions. These include communications satellites like Starlink; space stations such as the ISS; scientific satellites like the Hubble; Earth observation satellites from companies like Planet Labs, Umbra, and HawkEye 360; GPS; miniature CubeSats for education and research; and military/defense satellites.
