OPTUS D1 — Live Satellite Tracking (NORAD 29495)
Track OPTUS D1 (NORAD catalog number 29495) 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 2006's 43rd orbital launch (COSPAR designation 2006-043B). 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 7,294 revolutions of Earth.
Moving at about 3.08 km/s, OPTUS D1 flies a geosynchronous orbit roughly 35,786 km up: its 23.9-hour period matches Earth's rotation, but at 3.2° inclination it is not geostationary — seen from the ground it traces a daily figure-eight around a fixed longitude, swinging about 3° north and south of the equator. The orbit is essentially circular (eccentricity 0.0004). Its near-equatorial 3.2° inclination keeps it above the tropics at all times. Its orbital plane crosses the equator northbound at right ascension 78.6°.

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