PROVES-ELECTRA

PROVES-ELECTRA is an active satellite operated by United States, launched on 1998-11-20 from Baikonur, Kazakhstan on the 77KM No. 17501 launch. With over 28 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 408 km and 422 km with an inclination of 51.6°. It travels at approximately 27,591 km/h (7.66 km/s), completing one full orbit every 93 minutes — that’s roughly 15.51 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~1–3 years. Orbital Radar tracks PROVES-ELECTRA in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

PROVES-ELECTRA orbits at an average altitude of 415 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 PROVES-ELECTRA’s average altitude, there are currently 2,706 active payloads and 110 tracked debris or rocket body fragments — notable neighbours include STARLINK-1008, STARLINK-1012, STARLINK-1017. This makes it one of the more crowded altitude bands, containing roughly 15.3% of all active satellites. With an inclination of 51.6°, PROVES-ELECTRA passes over latitudes between 51.6°N and 51.6°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 12,566 active satellites in total, of which 2,515 share a similar altitude band with PROVES-ELECTRA.
