RADIO 7

RADIO 7 is an active satellite operated by Russia (CIS), launched on 1981-12-17 from PKMTR. With over 45 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 1,621 km and 1,661 km with an inclination of 83.0°. It travels at approximately 25,392 km/h (7.05 km/s), completing one full orbit every 119 minutes — that’s roughly 12.09 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is thousands of years. Orbital Radar tracks RADIO 7 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

RADIO 7 orbits in the upper reaches of Low Earth Orbit, above 1,000 km. At this altitude, atmospheric drag is negligible and objects can remain in orbit for thousands of years without active deorbiting. This region is used by satellite broadband constellations like OneWeb and by scientific missions that need stable, long-duration orbits away from the densest debris bands. The high inclination typical at this altitude provides near-global coverage.
