PRSC-E03

PRSC-E03 is an active satellite operated by China, launched on 2026-04-25 from Taiyuan, China. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Low Earth Orbit (LEO) at altitudes between 544 km and 549 km with an inclination of 38.0°. It travels at approximately 27,327 km/h (7.59 km/s), completing one full orbit every 96 minutes — that’s roughly 15.07 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 PRSC-E03 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

PRSC-E03 orbits at an average altitude of 547 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 PRSC-E03’s average altitude, there are currently 3,506 active payloads and 356 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 20.1% of all active satellites. With an inclination of 38.0°, PRSC-E03 passes over latitudes between 38.0°N and 38.0°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 180 share a similar altitude band with PRSC-E03.
