ACTS

ACTS is an active satellite operated by United States, launched on 1993-09-12 from Cape Canaveral, Florida. With over 33 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 35,557 km and 36,016 km with an inclination of 14.6°. 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 ACTS in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

ACTS 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 14.6°, 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 ACTS’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. United States operates approximately 12,339 active satellites in total, of which 146 share a similar altitude band with ACTS.
