📖 About This Object
DFH 3-1 is an active satellite operated by China, launched on 1994-11-29 from Xichang, China. With over 32 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 35,189 km and 36,001 km with an inclination of 13.7°. It travels at approximately 11,095 km/h (3.08 km/s), completing one full orbit every 23 hours 46 minutes — that’s roughly 1.01 orbits per day. It is part of the Geo Protected Plus constellation group. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks DFH 3-1 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
DFH 3-1 occupies geostationary orbit (GEO) at approximately 35,786 km above the equator. At this precise altitude, the satellite’s orbital period matches the Earth’s rotation — so it appears to hover over a fixed point on the equator. GEO is used primarily for broadcast television, weather monitoring (Meteosat, GOES) and wideband communications. Only about 560 active satellites occupy the GEO belt, but its commercial value is immense: a single GEO slot can cover roughly one-third of the Earth’s surface. This satellite has a non-zero inclination of 13.7°, meaning it traces a small figure-of-eight pattern relative to the ground rather than remaining perfectly stationary. This can indicate an aging satellite whose stationkeeping fuel is running low, or a deliberate inclined-orbit strategy to extend operational life.
DFH 3-1 orbits at approximately 35,595 km altitude, where the orbital period matches the Earth’s 24-hour rotation. This means it stays above the same point on the equator at all times. Its actual speed is still 11,095 km/h — it just keeps pace with the ground below. With an inclination of 13.7°, it actually traces a small figure-of-eight pattern rather than remaining perfectly fixed.
DFH 3-1 is operated by China. It is catalogued by the U.S. Space Surveillance Network under NORAD ID 23415. You can track DFH 3-1 in real time on Orbital Radar’s live tracker.

Yes — Orbital Radar tracks DFH 3-1 (NORAD ID 23415) using the latest TLE (two-line element set) data from Space-Track and CelesTrak. Open the live tracker to see its current position, altitude, speed and orbital path updated in real time.
DFH 3-1 travels at approximately 11,095 km/h (6,894 mph) — roughly 3.08 km/s. Despite this high speed, it appears stationary from the ground because it matches the Earth’s rotation. Geostationary satellites are actually slower than LEO satellites because orbital velocity decreases with altitude.
DFH 3-1 is a member of the Geo Protected Plus constellation. Satellites in this group work together to provide coordinated coverage, typically in similar orbital planes at comparable altitudes. You can view all Geo Protected Plus satellites on Orbital Radar’s live tracker.
