ASTROSAT — Live Satellite Tracking (NORAD 40930)
Track ASTROSAT (NORAD catalog number 40930) 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 2015, launched on the 52nd orbital launch of that year (COSPAR designation 2015-052A). As of this element set it had completed roughly 59,201 revolutions of Earth.
Moving at about 7.55 km/s, ASTROSAT flies in low Earth orbit at an altitude of roughly 623 × 633 km, completing one revolution every 97.1 minutes — about 14.8 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0008). Its near-equatorial 6.0° inclination keeps it above the tropics at all times. Its orbital plane crosses the equator northbound at right ascension 285.3°. Earth's equatorial bulge drifts that plane westward about 7.16° per day.

About the Other Active Satellites group
ASTROSAT 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 ASTROSAT from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, ASTROSAT is visible only around dawn and dusk, when your sky is dark but the satellite is still sunlit — and whether you can spot it depends on its size and reflectivity. See pass predictions for your location for when it is above your horizon and sunlit.
