YAOGAN 27

YAOGAN 27 is an active satellite operated by Chinese Ministry of National Defense (China), launched on 2015-08-27 from Taiyuan, China. After 11 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Low Earth Orbit (LEO) at altitudes between 1,194 km and 1,206 km with an inclination of 100.1°. It travels at approximately 26,121 km/h (7.26 km/s), completing one full orbit every 109 minutes — that’s roughly 13.16 orbits per day. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is thousands of years. Orbital Radar tracks YAOGAN 27 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

YAOGAN 27 orbits at an average altitude of 1,200 km in the uppermost reaches of Low Earth Orbit. At this altitude, orbital decay is effectively zero without active deorbiting, and coverage footprints are significantly larger than lower LEO, though at the cost of higher latency. Within ±50 km of YAOGAN 27’s average altitude, there are currently 735 active payloads and 205 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0012, ONEWEB-0010, ONEWEB-0008. With an inclination of 100.1°, YAOGAN 27 passes over latitudes between 100.1°N and 100.1°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 67 share a similar altitude band with YAOGAN 27.
