O3B FM3 — Live Satellite Tracking (NORAD 40079)
Track O3B FM3 (NORAD catalog number 40079) live on the WatchSat interactive 3D globe above. Its position is propagated in real time from the latest CelesTrak two-line element set using the SGP4/SDP4 orbital model — the same math professional trackers run. It has been on orbit since 2014, launched on the 38th orbital launch of that year (COSPAR designation 2014-038A). It went up together with 3 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 21,714 revolutions of Earth.
Moving at about 5.26 km/s, O3B FM3 operates in medium Earth orbit at roughly 8,068–8,078 km altitude, taking about 4.8 hours per revolution (5.00 orbits a day). The orbit is essentially circular (eccentricity 0.0003). Its near-equatorial 0.0° inclination keeps it above the tropics at all times. Its orbital plane crosses the equator northbound at right ascension 353.1°. Earth's equatorial bulge drifts that plane westward about 0.57° per day.

About the Other Active Satellites group
O3B FM3 is one of 4,471 active satellites in WatchSat's general catalog — the broad population of Earth-observation, communications, science, amateur-radio and technology spacecraft outside the giant broadband constellations. Browse all other active satellites live in 3D.
Can you see O3B FM3 from the ground?
Not with the naked eye. At its altitude O3B FM3 is far beyond unaided visibility — following satellites this high takes a telescope and good timing. You can still track it precisely in the live 3D view above, or check pass predictions for your location.
