GSAT-18 — Live Satellite Tracking (NORAD 41793)
Track GSAT-18 (NORAD catalog number 41793) 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 2016, launched on the 60th orbital launch of that year (COSPAR designation 2016-060A). 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 3,635 revolutions of Earth.
Moving at about 3.08 km/s, GSAT-18 sits in the geostationary belt roughly 35,786 km above the equator, where its 23.9-hour orbit matches Earth's rotation — seen from the ground it stays parked over the same longitude around the clock. The orbit is essentially circular (eccentricity 0.0003). Its near-equatorial 0.1° inclination keeps it above the tropics at all times. Its orbital plane crosses the equator northbound at right ascension 90.5°.

This page's orbital elements come from the CelesTrak catalog of 2026-09-08. The live 3D view above fetches its own current CelesTrak data when the page opens, through an edge cache that refreshes roughly every 30 minutes.
About the Navigation group
GSAT-18 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 GSAT-18 from the ground?
Not with the naked eye. At its altitude GSAT-18 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.
