QIANFAN-39

QIANFAN-39 is an active satellite operated by China, launched on 2024-12-05 from Taiyuan, China. It orbits in Low Earth Orbit (LEO) at altitudes between 795 km and 818 km with an inclination of 89.0°. It travels at approximately 26,828 km/h (7.45 km/s), completing one full orbit every 101 minutes — that’s roughly 14.26 orbits per day. It is part of the Qianfan constellation group. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks QIANFAN-39 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

QIANFAN-39 orbits at an average altitude of 807 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 QIANFAN-39’s average altitude, there are currently 441 active payloads and 2,295 tracked debris or rocket body fragments — notable neighbours include NOAA 20, ONEWEB-0179, ONEWEB-0455. With an inclination of 89.0°, QIANFAN-39 passes over latitudes between 89.0°N and 89.0°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 106 share a similar altitude band with QIANFAN-39.
