BEIDOU 1D

BEIDOU 1D is an active satellite operated by China National Space Administration (China), launched on 2007-02-02 from Xichang, China. After 19 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Geostationary Orbit (GEO) at altitudes between 35,875 km and 36,329 km with an inclination of 9.9°. It travels at approximately 11,028 km/h (3.06 km/s), completing one full orbit every 24.2 hours — that’s roughly 0.99 orbits per day. It is part of the Beidou constellation group. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks BEIDOU 1D in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

BEIDOU 1D 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 9.9°, 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 BEIDOU 1D’s average altitude, there are currently 177 active payloads and 9 tracked debris or rocket body fragments. China operates approximately 1,219 active satellites in total, of which 14 share a similar altitude band with BEIDOU 1D.
