STAR ONE D1 — Live Satellite Tracking (NORAD 41904)
Track STAR ONE D1 (NORAD catalog number 41904) 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 is object B of 2016's 82nd orbital launch (COSPAR designation 2016-082B). 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 3,559 revolutions of Earth.
Moving at about 3.08 km/s, STAR ONE D1 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 0.0002). Its near-equatorial 0.0° inclination keeps it above the tropics at all times. Its orbital plane crosses the equator northbound at right ascension 100.5°.

About the Other Active Satellites group
STAR ONE D1 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 STAR ONE D1 from the ground?
Not with the naked eye. At its altitude STAR ONE D1 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.
