GSAT0223 (GALILEO 27) — Live Satellite Tracking (NORAD 49809)
Track GSAT0223 (GALILEO 27) (NORAD catalog number 49809) 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 2021, launched on the 116th orbital launch of that year (COSPAR designation 2021-116A). 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 2,950 revolutions of Earth.
Moving at about 3.67 km/s, GSAT0223 (GALILEO 27) operates in medium Earth orbit at roughly 23,217–23,241 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
GSAT0223 (GALILEO 27) 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 GSAT0223 (GALILEO 27) from the ground?
Not with the naked eye. At its altitude GSAT0223 (GALILEO 27) 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.
