QZS-1R

QZS-1R is an active satellite operated by Japan Aerospace Exploration Agency (JAXA) (Japan), launched on 2021-10-26 from TNSTA. It orbits in Geostationary Orbit (GEO) at altitudes between 32,608 km and 38,974 km with an inclination of 37.5°. It travels at approximately 11,069 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 QZS-1R in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

QZS-1R 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 37.5°, 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 QZS-1R’s average altitude, there are currently 715 active payloads and 60 tracked debris or rocket body fragments — notable neighbours include ASTRA 1N, GOES 16, TDRS 13. Japan operates approximately 189 active satellites in total, of which 26 share a similar altitude band with QZS-1R.
