USA 157

USA 157 is an active satellite operated by US Air Force (United States), launched on 2001-02-27 from Cape Canaveral, Florida. With over 25 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 35,620 km and 35,951 km with an inclination of 11.6°. 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 USA 157 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

USA 157 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 11.6°, 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 USA 157’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 12,360 active satellites in total, of which 146 share a similar altitude band with USA 157.
