COSMOS 342

COSMOS 342 is an active satellite operated by OKB-10 (Russia (CIS)), launched on 1970-04-25 from Plesetsk Cosmodrome, Russia on the Strela-1M launch. After more than 56 years in orbit, it is one of the longest-surviving objects in the space catalogue. It orbits in Low Earth Orbit (LEO) at altitudes between 1,310 km and 1,467 km with an inclination of 74.0°. It travels at approximately 25,802 km/h (7.17 km/s), completing one full orbit every 114 minutes — that’s roughly 12.68 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is thousands of years. Orbital Radar tracks COSMOS 342 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

COSMOS 342 orbits at an average altitude of 1,389 km in the uppermost reaches of Low Earth Orbit. At this altitude, orbital decay is effectively zero without active deorbiting, and coverage footprints are significantly larger than lower LEO, though at the cost of higher latency. Within ±50 km of COSMOS 342’s average altitude, there are currently 261 active payloads and 253 tracked debris or rocket body fragments. With an inclination of 74.0°, COSMOS 342 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 1,552 active satellites in total, of which 214 share a similar altitude band with COSMOS 342.
