TIANQI-6

TIANQI-6 is an active satellite operated by Guodian Gaoke (China), launched on 2020-10-26 from Xichang Satellite Launch Center, China on the YG-30-07 launch. It orbits in Low Earth Orbit (LEO) at altitudes between 535 km and 550 km with an inclination of 35.0°. It travels at approximately 27,335 km/h (7.59 km/s), completing one full orbit every 95 minutes — that’s roughly 15.08 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Orbital Radar tracks TIANQI-6 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

TIANQI-6 orbits at an average altitude of 543 km in the core of Low Earth Orbit, the most heavily utilised altitude band. The balance of moderate drag (limiting debris accumulation) and short signal path (enabling low-latency links and high-resolution imaging) makes this regime the default for most commercial and government missions. Within ±50 km of TIANQI-6’s average altitude, there are currently 1,441 active payloads and 374 tracked debris or rocket body fragments — notable neighbours include STARLINK-1184, STARLINK-1276, STARLINK-1451. This makes it one of the more crowded altitude bands, containing roughly 7.6% of all active satellites. With an inclination of 35.0°, TIANQI-6 passes over latitudes between 35.0°N and 35.0°S, covering the tropical and temperate zones where most of the world’s population resides. Low-to-mid inclination orbits are efficient to reach from equatorial and mid-latitude launch sites. China operates approximately 1,341 active satellites in total, of which 194 share a similar altitude band with TIANQI-6.
