GSAT0221 (GALILEO 25) — Live Satellite Tracking (NORAD 43564)
Track GSAT0221 (GALILEO 25) (NORAD catalog number 43564) 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 2018, launched on the 60th orbital launch of that year (COSPAR designation 2018-060A). 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 5,051 revolutions of Earth.
Moving at about 3.67 km/s, GSAT0221 (GALILEO 25) operates in medium Earth orbit at roughly 23,217–23,242 km altitude, taking about 14.1 hours per revolution (1.70 orbits a day). The orbit is essentially circular (eccentricity 0.0004). Inclined 57.1° to the equator, it overflies every latitude up to about 57° north and south. Its orbital plane crosses the equator northbound at right ascension 339.6°.

About the Navigation group
GSAT0221 (GALILEO 25) 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 GSAT0221 (GALILEO 25) from the ground?
Not with the naked eye. At its altitude GSAT0221 (GALILEO 25) 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.
