WEINA 1B

WEINA 1B is an active satellite operated by Shanghai Micro Satellite Engineering Center (China), launched on 2018-04-10 from Jiuquan, China. It orbits in Low Earth Orbit (LEO) at altitudes between 884 km and 1,295 km with an inclination of 63.4°. It travels at approximately 26,314 km/h (7.31 km/s), completing one full orbit every 107 minutes — that’s roughly 13.45 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~500–1,000 years. Orbital Radar tracks WEINA 1B in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

WEINA 1B orbits at an average altitude of 1,090 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 WEINA 1B’s average altitude, there are currently 181 active payloads and 391 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0041. With an inclination of 63.4°, WEINA 1B passes over latitudes between 63.4°N and 63.4°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. China operates approximately 1,218 active satellites in total, of which 159 share a similar altitude band with WEINA 1B.
