COSMOS 1670

COSMOS 1670 is an active satellite operated by Russia (CIS), launched on 1985-08-01 from Baikonur, Kazakhstan. With over 41 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 911 km and 989 km with an inclination of 64.9°. It travels at approximately 26,564 km/h (7.38 km/s), completing one full orbit every 104 minutes — that’s roughly 13.84 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks COSMOS 1670 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

COSMOS 1670 orbits at an average altitude of 950 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 1670’s average altitude, there are currently 308 active payloads and 1,091 tracked debris or rocket body fragments. With an inclination of 64.9°, COSMOS 1670 passes over latitudes between 64.9°N and 64.9°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 173 share a similar altitude band with COSMOS 1670.
