SZ-22 MODULE

SZ-22 MODULE is an active satellite operated by China, launched on 2025-11-25 from Jiuquan, China on the Shenzhou 22 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 378 km and 390 km with an inclination of 41.5°. It travels at approximately 27,654 km/h (7.68 km/s), completing one full orbit every 92 minutes — that’s roughly 15.61 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 months to ~1 year. Orbital Radar tracks SZ-22 MODULE in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

SZ-22 MODULE orbits at an average altitude of 384 km in the lower reaches of Low Earth Orbit, where atmospheric drag is significant and orbital lifetimes are measured in months to a few years. This is the busiest corridor in space — home to crewed spacecraft, rapid-revisit imaging satellites and the densest part of the Starlink constellation. Within ±50 km of SZ-22 MODULE’s average altitude, there are currently 1,259 active payloads and 72 tracked debris or rocket body fragments — notable neighbours include STARLINK-1008, STARLINK-1012, STARLINK-1020. This makes it one of the more crowded altitude bands, containing roughly 7.1% of all active satellites. With an inclination of 41.5°, SZ-22 MODULE passes over latitudes between 41.5°N and 41.5°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 1,244 active satellites in total, of which 34 share a similar altitude band with SZ-22 MODULE.
