COSMOS 1382 DEB

COSMOS 1382 DEB is a tracked piece of space debris attributed to Russia (CIS), launched on 1982-06-25 from PKMTR. With over 44 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Medium Earth Orbit (MEO) at altitudes between 1,049 km and 39,372 km with an inclination of 62.3°. It travels at approximately 13,941 km/h (3.87 km/s), completing one full orbit every 11 hours 59 minutes — that’s roughly 2.00 orbits per day. Its orbital eccentricity of 0.7209 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. As orbital debris, COSMOS 1382 DEB poses a potential collision risk to operational satellites in nearby orbits and is continuously monitored by the U.S. Space Surveillance Network and other tracking systems.

COSMOS 1382 DEB orbits at an average altitude of 20,211 km in Medium Earth Orbit, the region between LEO and GEO (2,000–35,786 km). MEO’s higher altitude gives each satellite a much larger ground footprint than LEO, meaning fewer spacecraft are needed for global coverage — but signal latency is higher and radiation from the Van Allen belts is a significant design constraint. Within ±50 km of COSMOS 1382 DEB’s average altitude, there are currently 97 active payloads and 19 tracked debris or rocket body fragments — notable neighbours include GPS BIIR-5 (PRN 22), GPS BIIR-8 (PRN 16), GPS BIIR-11 (PRN 19). With an inclination of 62.3°, COSMOS 1382 DEB passes over latitudes between 62.3°N and 62.3°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 1,286 active satellites in total, of which 50 share a similar altitude band with COSMOS 1382 DEB.
