HULIANWANG DIGUI-117

HULIANWANG DIGUI-117 is an active satellite operated by China, launched on 2025-12-08 from Taiyuan, China. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Low Earth Orbit (LEO) at altitudes between 1,166 km and 1,170 km with an inclination of 86.5°. It travels at approximately 26,177 km/h (7.27 km/s), completing one full orbit every 109 minutes — that’s roughly 13.24 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 Hulianwang constellation group. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~500–1,000 years. Orbital Radar tracks HULIANWANG DIGUI-117 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

HULIANWANG DIGUI-117 orbits at an average altitude of 1,168 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 HULIANWANG DIGUI-117’s average altitude, there are currently 785 active payloads and 260 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0012, ONEWEB-0010, ONEWEB-0008. With an inclination of 86.5°, HULIANWANG DIGUI-117 passes over latitudes between 86.5°N and 86.5°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. China operates approximately 1,219 active satellites in total, of which 174 share a similar altitude band with HULIANWANG DIGUI-117.
