COSMOS 2548

COSMOS 2548 is an active satellite operated by Defense Ministry (Russia (CIS)), launched on 2020-12-03 from PKMTR. It orbits in Low Earth Orbit (LEO) at altitudes between 1,482 km and 1,506 km with an inclination of 82.5°. It travels at approximately 25,628 km/h (7.12 km/s), completing one full orbit every 116 minutes — that’s roughly 12.43 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is thousands of years. Orbital Radar tracks COSMOS 2548 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

COSMOS 2548 orbits at an average altitude of 1,494 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 2548’s average altitude, there are currently 258 active payloads and 252 tracked debris or rocket body fragments. With an inclination of 82.5°, COSMOS 2548 passes over latitudes between 82.5°N and 82.5°S, providing near-global coverage including the polar regions. Polar and near-polar orbits are used for reconnaissance, weather monitoring and Earth-observation missions that need to image every part of the planet. Russia (CIS) operates approximately 1,286 active satellites in total, of which 249 share a similar altitude band with COSMOS 2548.
