QIANFAN-155

QIANFAN-155 is an active satellite operated by China, launched on 2026-05-17 from Wenchang, China on the Qianfan 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 987 km and 1,016 km with an inclination of 89.0°. It travels at approximately 26,471 km/h (7.35 km/s), completing one full orbit every 105 minutes — that’s roughly 13.66 orbits per day. It is part of the Qianfan constellation group. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~500–1,000 years. Orbital Radar tracks QIANFAN-155 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

QIANFAN-155 orbits at an average altitude of 1,002 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-155’s average altitude, there are currently 251 active payloads and 852 tracked debris or rocket body fragments. With an inclination of 89.0°, QIANFAN-155 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 1,211 active satellites in total, of which 63 share a similar altitude band with QIANFAN-155.
