MERIDIAN 6

MERIDIAN 6 is an active satellite operated by Military Space Forces (VKS) (Russia (CIS)), launched on 2012-11-14 from Plesetsk Cosmodrome, Russia on the Meridian No. 16L launch. After 14 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Medium Earth Orbit (MEO) at altitudes between 595 km and 39,743 km with an inclination of 63.7°. It travels at approximately 13,952 km/h (3.88 km/s), completing one full orbit every 11 hours 57 minutes — that’s roughly 2.01 orbits per day. Its orbital eccentricity of 0.7375 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. Orbital Radar tracks MERIDIAN 6 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

MERIDIAN 6 orbits at an average altitude of 20,169 km in Medium Earth Orbit, the region between LEO and GEO (2,000–35,786 km). MEO’s higher altitude gives each satellite a much larger ground footprint than LEO, meaning fewer spacecraft are needed for global coverage — but signal latency is higher and radiation from the Van Allen belts is a significant design constraint. Within ±50 km of MERIDIAN 6’s average altitude, there are currently 103 active payloads and 14 tracked debris or rocket body fragments. With an inclination of 63.7°, MERIDIAN 6 passes over latitudes between 63.7°N and 63.7°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 1,536 active satellites in total, of which 54 share a similar altitude band with MERIDIAN 6.
