COSMOS 1481

COSMOS 1481 is an active satellite operated by Russia (CIS), launched on 1983-07-08 from PKMTR. With over 43 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Medium Earth Orbit (MEO) at altitudes between 5,144 km and 34,695 km with an inclination of 70.6°. It travels at approximately 14,018 km/h (3.89 km/s), completing one full orbit every 11 hours 47 minutes — that’s roughly 2.04 orbits per day. Its orbital eccentricity of 0.5620 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. Orbital Radar tracks COSMOS 1481 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

COSMOS 1481 operates in Medium Earth Orbit (MEO), the region between LEO and GEO spanning roughly 2,000 to 35,786 km altitude. MEO is home to navigation constellations (GPS at ~20,200 km, Galileo at ~23,222 km, GLONASS at ~19,130 km) and some communications systems. The higher altitude gives each satellite a much larger ground footprint than LEO, meaning fewer satellites are needed for global coverage, but signal latency is higher and radiation exposure — particularly from the Van Allen belts — is a significant design challenge.
