COSMOS 1763

COSMOS 1763 is an active satellite operated by Russia (CIS), launched on 1986-07-16 from PKMTR. With over 40 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 739 km and 783 km with an inclination of 74.0°. It travels at approximately 26,913 km/h (7.48 km/s), completing one full orbit every 100 minutes — that’s roughly 14.39 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~25–100 years. Orbital Radar tracks COSMOS 1763 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

COSMOS 1763 orbits at an average altitude of 761 km in the mid-LEO band, where atmospheric drag is minimal but radiation exposure remains manageable. Objects at this altitude persist for decades to centuries, making debris mitigation critical. This regime is popular for remote sensing constellations and scientific instruments that need stable, long-duration orbits. Within ±50 km of COSMOS 1763’s average altitude, there are currently 361 active payloads and 2,039 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0179. With an inclination of 74.0°, COSMOS 1763 passes over latitudes between 74.0°N and 74.0°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 48 share a similar altitude band with COSMOS 1763.
