COSMOS 1943

COSMOS 1943 is an active satellite operated by Russia (CIS), launched on 1988-05-15 from Baikonur, Kazakhstan. With over 38 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 833 km and 846 km with an inclination of 71.0°. It travels at approximately 26,766 km/h (7.44 km/s), completing one full orbit every 102 minutes — that’s roughly 14.16 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 ~100–500 years. Orbital Radar tracks COSMOS 1943 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

COSMOS 1943 orbits at an average altitude of 840 km in the upper LEO band, where atmospheric drag is negligible and objects can persist for centuries to millennia. This altitude is used by broadband constellations like OneWeb and by scientific missions requiring stable orbits far from the densest debris bands. Within ±50 km of COSMOS 1943’s average altitude, there are currently 271 active payloads and 2,138 tracked debris or rocket body fragments — notable neighbours include NOAA 20, ONEWEB-0179, ONEWEB-0455. With an inclination of 71.0°, COSMOS 1943 passes over latitudes between 71.0°N and 71.0°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 48 share a similar altitude band with COSMOS 1943.
