WEINA 1A

WEINA 1A is an active satellite operated by Shanghai Micro Satellite Engineering Center (China), launched on 2018-01-25 from Xichang, China. It orbits in Low Earth Orbit (LEO) at altitudes between 562 km and 565 km with an inclination of 35.0°. It travels at approximately 27,294 km/h (7.58 km/s), completing one full orbit every 96 minutes — that’s roughly 15.01 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 ~3–10 years. Orbital Radar tracks WEINA 1A in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

WEINA 1A orbits at an average altitude of 564 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 WEINA 1A’s average altitude, there are currently 3,171 active payloads and 460 tracked debris or rocket body fragments — notable neighbours include STARLINK-1184, STARLINK-1276, ONEWEB-0050. This makes it one of the more crowded altitude bands, containing roughly 18.2% of all active satellites. With an inclination of 35.0°, WEINA 1A 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 1,219 active satellites in total, of which 137 share a similar altitude band with WEINA 1A.
