O/OREOS (USA 219)

O/OREOS (USA 219) is an active satellite operated by National Aeronautics and Space Administration (NASA)-Ames Research Center/Stanford University (United States), launched on 2010-11-20 from Kodiak, Alaska. After 16 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Low Earth Orbit (LEO) at altitudes between 578 km and 595 km with an inclination of 72.0°. It travels at approximately 27,249 km/h (7.57 km/s), completing one full orbit every 96 minutes — that’s roughly 14.94 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Orbital Radar tracks O/OREOS (USA 219) in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

O/OREOS (USA 219) orbits at an average altitude of 587 km in the core of Low Earth Orbit, the most heavily utilised altitude band. The balance of moderate drag (limiting debris accumulation) and short signal path (enabling low-latency links and high-resolution imaging) makes this regime the default for most commercial and government missions. Within ±50 km of O/OREOS (USA 219)’s average altitude, there are currently 3,232 active payloads and 591 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0050, STARLINK-3005, STARLINK-3090. This makes it one of the more crowded altitude bands, containing roughly 18.6% of all active satellites. With an inclination of 72.0°, O/OREOS (USA 219) passes over latitudes between 72.0°N and 72.0°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. United States operates approximately 12,339 active satellites in total, of which 2,687 share a similar altitude band with O/OREOS (USA 219).
