INTELSAT 4A-F6

INTELSAT 4A-F6 is an active satellite operated by ITSO, launched on 1978-03-31 from Cape Canaveral, Florida. With over 48 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 35,755 km and 35,818 km with an inclination of 8.8°. 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. It is part of the Intelsat constellation group. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks INTELSAT 4A-F6 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

INTELSAT 4A-F6 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 8.8°, 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.
