SES MPOWER-F13

SES MPOWER-F13 is an active satellite operated by O3B SES (SES), launched on 2026-09-13 from Cape Canaveral Space Force Station, United States on the O3b mPOWER 11/13 launch. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Medium Earth Orbit (MEO) at altitudes between 1,216 km and 7,102 km with an inclination of 14.1°. It travels at approximately 22,149 km/h (6.15 km/s), completing one full orbit every 2 hours 59 minutes — that’s roughly 8.03 orbits per day. Its orbital eccentricity of 0.2795 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. It is part of the Ses constellation group. Orbital Radar tracks SES MPOWER-F13 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

SES MPOWER-F13 orbits at an average altitude of 4,159 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 SES MPOWER-F13’s average altitude, there are currently 3 active payloads and 1 tracked debris or rocket body fragment. This is a relatively sparse altitude band, containing less than 1% of all active satellites. With an inclination of 14.1°, SES MPOWER-F13 passes over latitudes between 14.1°N and 14.1°S, concentrating coverage over equatorial and near-equatorial regions. Low-inclination orbits maximise revisit rates over specific tropical zones. SES operates approximately 80 active satellites in total, of which 3 share a similar altitude band with SES MPOWER-F13.
