GSAT0101 (GALILEO-PFM) — Live Satellite Tracking (NORAD 37846)
Track GSAT0101 (GALILEO-PFM) (NORAD catalog number 37846) 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 2011, launched on the 60th orbital launch of that year (COSPAR designation 2011-060A). It went up together with 1 other satellite from that launch still in the active catalog. As of this element set it had completed roughly 9,243 revolutions of Earth.
Moving at about 3.67 km/s, GSAT0101 (GALILEO-PFM) operates in medium Earth orbit at roughly 23,228–23,231 km altitude, taking about 14.1 hours per revolution (1.70 orbits a day). The orbit is essentially circular (eccentricity 0.0000). Inclined 57.0° to the equator, it overflies every latitude up to about 57° north and south. Its orbital plane crosses the equator northbound at right ascension 339.7°.

About the Navigation group
GSAT0101 (GALILEO-PFM) is part of Europe's Galileo fleet — one of 173 global-navigation satellites in the WatchSat catalog across GPS, GLONASS, Galileo and BeiDou. GNSS spacecraft broadcast precise time signals from orbits around 20,000 km up; a phone fixes its position by comparing several of them at once. See the whole navigation group live in 3D.
Can you see GSAT0101 (GALILEO-PFM) from the ground?
Not with the naked eye. At its altitude GSAT0101 (GALILEO-PFM) 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.
