COSMOS 1393

COSMOS 1393 is an active satellite operated by Russia (CIS), launched on 1982-07-21 from PKMTR. With over 44 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 1,470 km and 1,482 km with an inclination of 74.0°. It travels at approximately 25,658 km/h (7.13 km/s), completing one full orbit every 115 minutes — that’s roughly 12.47 orbits per day. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is thousands of years. Orbital Radar tracks COSMOS 1393 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

COSMOS 1393 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.
