HULIANWANG DIGUI-199

HULIANWANG DIGUI-199 is an active satellite operated by China SatNet (Guowang) (China), launched on 2026-09-17 from Wenchang Space Launch Site, China on the WHDW 25 launch. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Low Earth Orbit (LEO) at altitudes between 1,090 km and 1,092 km with an inclination of 50.0°. It travels at approximately 26,311 km/h (7.31 km/s), completing one full orbit every 107 minutes — that’s roughly 13.37 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-199 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

HULIANWANG DIGUI-199 orbits at an average altitude of 1,091 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-199’s average altitude, there are currently 344 active payloads and 534 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0041. With an inclination of 50.0°, HULIANWANG DIGUI-199 passes over latitudes between 50.0°N and 50.0°S, covering the tropical and temperate zones where most of the world’s population resides. Low-to-mid inclination orbits are efficient to reach from equatorial and mid-latitude launch sites. China operates approximately 1,694 active satellites in total, of which 288 share a similar altitude band with HULIANWANG DIGUI-199.
