COSMOS 1354

COSMOS 1354 is an active satellite operated by Russia (CIS), launched on 1982-04-28 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 775 km and 790 km with an inclination of 74.0°. It travels at approximately 26,873 km/h (7.46 km/s), completing one full orbit every 101 minutes — that’s roughly 14.33 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~25–100 years. Orbital Radar tracks COSMOS 1354 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

COSMOS 1354 orbits at an average altitude of 783 km in the mid-LEO band, where atmospheric drag is minimal but radiation exposure remains manageable. Objects at this altitude persist for decades to centuries, making debris mitigation critical. This regime is popular for remote sensing constellations and scientific instruments that need stable, long-duration orbits. Within ±50 km of COSMOS 1354’s average altitude, there are currently 403 active payloads and 2,218 tracked debris or rocket body fragments — notable neighbours include NOAA 20, ONEWEB-0179, ONEWEB-0455. With an inclination of 74.0°, COSMOS 1354 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 1,285 active satellites in total, of which 60 share a similar altitude band with COSMOS 1354.
