TJS-19

TJS-19 is an active satellite operated by China, launched on 2025-05-12 from Xichang, China. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Geostationary Orbit (GEO) at altitudes between 35,773 km and 35,798 km with an inclination of 3.3°. It travels at approximately 11,070 km/h (3.07 km/s), completing one full orbit every ~24 hours (geosynchronous) — that’s roughly 1.00 orbits per day. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks TJS-19 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

TJS-19 occupies geostationary orbit at approximately 35,786 km above the equator, where its orbital period matches the Earth’s 24-hour rotation. From the ground, it appears to hover over a fixed point — ideal for broadcast television, weather monitoring and wideband communications. With an inclination of 3.3°, it traces a small figure-of-eight pattern relative to the equator rather than remaining perfectly stationary, which can indicate aging stationkeeping fuel or a deliberate inclined-orbit strategy. Within ±50 km of TJS-19’s average altitude, there are currently 713 active payloads and 58 tracked debris or rocket body fragments — notable neighbours include ASTRA 1N, GOES 16, TDRS 13. China operates approximately 1,219 active satellites in total, of which 108 share a similar altitude band with TJS-19.
