METEOSAT 4 (MOP 1)

METEOSAT 4 (MOP 1) is an active satellite operated by EUMETSAT (ESA (European Space Agency)), launched on 1989-03-06 from Guiana Space Centre, Kourou. With over 37 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 36,607 km and 36,787 km with an inclination of 14.9°. It travels at approximately 10,952 km/h (3.04 km/s), completing one full orbit every 24.7 hours — that’s roughly 0.97 orbits per day. It is part of the Weather constellation group. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks METEOSAT 4 (MOP 1) in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

METEOSAT 4 (MOP 1) occupies geostationary orbit at approximately 35,786 km above the equator, where its orbital period matches the Earth’s 24-hour rotation. From the ground, it appears to hover over a fixed point — ideal for broadcast television, weather monitoring and wideband communications. With an inclination of 14.9°, it traces a small figure-of-eight pattern relative to the equator rather than remaining perfectly stationary, which can indicate aging stationkeeping fuel or a deliberate inclined-orbit strategy. Within ±50 km of METEOSAT 4 (MOP 1)’s average altitude, there are currently 7 active payloads and 3 tracked debris or rocket body fragments. ESA (European Space Agency) operates approximately 93 active satellites in total, of which 2 share a similar altitude band with METEOSAT 4 (MOP 1).
