GAOFEN 9 02

GAOFEN 9 02 is an active satellite operated by China National Academy of Sciences (CNSAS) (China), launched on 2020-05-31 from Jiuquan, China. It orbits in Low Earth Orbit (LEO) at altitudes between 478 km and 497 km with an inclination of 97.6°. It travels at approximately 27,445 km/h (7.62 km/s), completing one full orbit every 94 minutes — that’s roughly 15.26 orbits per day. Its near-polar, sun-synchronous orbit means it passes over any given point on Earth at approximately the same local solar time, ideal for consistent Earth observation lighting conditions. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~1–3 years. Orbital Radar tracks GAOFEN 9 02 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

GAOFEN 9 02 orbits at an average altitude of 488 km in a sun-synchronous orbit (SSO), a specialised subset of LEO where the orbital plane precesses to maintain a constant angle relative to the Sun. This provides consistent lighting conditions on every pass — essential for Earth observation, weather monitoring and environmental science. Within ±50 km of GAOFEN 9 02’s average altitude, there are currently 8,112 active payloads and 225 tracked debris or rocket body fragments — notable neighbours include STARLINK-1017, STARLINK-1039, STARLINK-1047. This makes it one of the more crowded altitude bands, containing roughly 46.5% of all active satellites. With an inclination of 97.6°, GAOFEN 9 02 passes over latitudes between 97.6°N and 97.6°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 1,218 active satellites in total, of which 189 share a similar altitude band with GAOFEN 9 02.
