HAIYANG 2D

HAIYANG 2D is an active satellite operated by China, launched on 2021-05-19 from Jiuquan, China. It orbits in Low Earth Orbit (LEO) at altitudes between 944 km and 960 km with an inclination of 66.0°. It travels at approximately 26,560 km/h (7.38 km/s), completing one full orbit every 104 minutes — that’s roughly 13.83 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks HAIYANG 2D in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

HAIYANG 2D orbits at an average altitude of 952 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 HAIYANG 2D’s average altitude, there are currently 320 active payloads and 1,084 tracked debris or rocket body fragments. With an inclination of 66.0°, HAIYANG 2D passes over latitudes between 66.0°N and 66.0°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 45 share a similar altitude band with HAIYANG 2D.
