COSMOS 1629

COSMOS 1629 is an active satellite operated by PVO (Russia (CIS)), launched on 1985-02-21 from Baikonur Cosmodrome, Kazakhstan on the Oko-S F2 launch. With over 41 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 35,725 km and 35,794 km with an inclination of 8.9°. It travels at approximately 11,073 km/h (3.08 km/s), completing one full orbit every ~24 hours (geosynchronous) — that’s roughly 1.00 orbits per day. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks COSMOS 1629 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

COSMOS 1629 occupies geostationary orbit at approximately 35,786 km above the equator, where its orbital period matches the Earth’s 24-hour rotation. From the ground, it appears to hover over a fixed point — ideal for broadcast television, weather monitoring and wideband communications. With an inclination of 8.9°, it traces a small figure-of-eight pattern relative to the equator rather than remaining perfectly stationary, which can indicate aging stationkeeping fuel or a deliberate inclined-orbit strategy. Within ±50 km of COSMOS 1629’s average altitude, there are currently 713 active payloads and 48 tracked debris or rocket body fragments — notable neighbours include ASTRA 1N, GOES 16, TDRS 13. Russia (CIS) operates approximately 1,547 active satellites in total, of which 120 share a similar altitude band with COSMOS 1629.
