USA 65 (DSP 15)

USA 65 (DSP 15) is an active satellite operated by United States, launched on 1990-11-13 from Cape Canaveral, Florida. With over 36 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 36,304 km and 36,337 km with an inclination of 14.1°. It travels at approximately 11,000 km/h (3.06 km/s), completing one full orbit every 24.4 hours — that’s roughly 0.98 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 65 (DSP 15) in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

USA 65 (DSP 15) 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 14.1°, 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.
