APSTAR-6E SPS — Live Satellite Tracking (NORAD 55447)

Track APSTAR-6E SPS (NORAD catalog number 55447) 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 C of 2023's 5th orbital launch (COSPAR designation 2023-005C). 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 10,345 revolutions of Earth.

Its speed swings from 4.79 km/s at apogee to 7.61 km/s at perigee. APSTAR-6E SPS operates in medium Earth orbit at roughly 2,071–7,032 km altitude, taking about 3.2 hours per revolution (7.61 orbits a day). The orbit is strongly elliptical (eccentricity 0.2271): each revolution swings from 2,071 km at perigee out to 7,032 km at apogee. Its 28.6° inclination keeps its ground track over the tropics and lower mid-latitudes. Its orbital plane crosses the equator northbound at right ascension 115.2°. Earth's equatorial bulge drifts that plane westward about 1.48° per day.

About the Other Active Satellites group

APSTAR-6E SPS is one of 4,802 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 APSTAR-6E SPS from the ground?

Not with the naked eye. At its altitude APSTAR-6E SPS 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 the “When can I see it?” panel in the live view.
