ONEWEB-0321

ONEWEB-0321 is an active satellite operated by OneWeb Satellites (United Kingdom), launched on 2021-09-14 from Baikonur, Kazakhstan. It orbits in Low Earth Orbit (LEO) at altitudes between 1,180 km and 1,183 km with an inclination of 87.9°. It travels at approximately 26,153 km/h (7.26 km/s), completing one full orbit every 109 minutes — that’s roughly 13.21 orbits per day. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. It is part of the Oneweb constellation group. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~500–1,000 years. Orbital Radar tracks ONEWEB-0321 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

ONEWEB-0321 orbits at an average altitude of 1,182 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 ONEWEB-0321’s average altitude, there are currently 841 active payloads and 237 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0012, ONEWEB-0010, ONEWEB-0008. With an inclination of 87.9°, ONEWEB-0321 passes over latitudes between 87.9°N and 87.9°S, providing near-global coverage including the polar regions. Polar and near-polar orbits are used for reconnaissance, weather monitoring and Earth-observation missions that need to image every part of the planet. United Kingdom operates approximately 720 active satellites in total, of which 649 share a similar altitude band with ONEWEB-0321.
