FREGAT DEB (TANK)

FREGAT DEB (TANK) is a tracked piece of space debris attributed to Russia (CIS), launched on 2017-12-26 from Baikonur Cosmodrome, Kazakhstan on the Angosat launch. It orbits in Medium Earth Orbit (MEO) at altitudes between 265 km and 2,135 km with an inclination of 50.4°. It travels at approximately 26,121 km/h (7.26 km/s), completing one full orbit every 109 minutes — that’s roughly 13.16 orbits per day. Its orbital eccentricity of 0.1235 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is thousands of years. As orbital debris, FREGAT DEB (TANK) 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.

FREGAT DEB (TANK) orbits at an average altitude of 1,200 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 FREGAT DEB (TANK)’s average altitude, there are currently 746 active payloads and 277 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0012, ONEWEB-0010, ONEWEB-0008. With an inclination of 50.4°, FREGAT DEB (TANK) passes over latitudes between 50.4°N and 50.4°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 1,550 active satellites in total, of which 16 share a similar altitude band with FREGAT DEB (TANK).
