COSMOS 2187

COSMOS 2187 is an active satellite operated by Russia (CIS), launched on 1992-06-03 from PKMTR. With over 34 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 1,401 km and 1,480 km with an inclination of 74.0°. It travels at approximately 25,716 km/h (7.14 km/s), completing one full orbit every 115 minutes — that’s roughly 12.56 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is thousands of years. Orbital Radar tracks COSMOS 2187 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

COSMOS 2187 orbits at an average altitude of 1,441 km in the uppermost reaches of Low Earth Orbit. At this altitude, orbital decay is effectively zero without active deorbiting, and coverage footprints are significantly larger than lower LEO, though at the cost of higher latency. Within ±50 km of COSMOS 2187’s average altitude, there are currently 379 active payloads and 191 tracked debris or rocket body fragments. With an inclination of 74.0°, COSMOS 2187 passes over latitudes between 74.0°N and 74.0°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. Russia (CIS) operates approximately 1,286 active satellites in total, of which 342 share a similar altitude band with COSMOS 2187.
