POISK

POISK is an active satellite operated by Russia (CIS), launched on 2009-11-10 from Baikonur, Kazakhstan. After 17 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Low Earth Orbit (LEO) at altitudes between 416 km and 422 km with an inclination of 51.6°. It travels at approximately 27,583 km/h (7.66 km/s), completing one full orbit every 93 minutes — that’s roughly 15.49 orbits per day. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~1–3 years. Orbital Radar tracks POISK in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

POISK orbits at an average altitude of 419 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 POISK’s average altitude, there are currently 2,639 active payloads and 130 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 15.1% of all active satellites. With an inclination of 51.6°, POISK 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. Russia (CIS) operates approximately 1,286 active satellites in total, of which 39 share a similar altitude band with POISK.
