ACS3 — Live Satellite Tracking (NORAD 59588)
Track ACS3 (NORAD catalog number 59588) 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 2024's 77th orbital launch (COSPAR designation 2024-077B). 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 12,562 revolutions of Earth.
Moving at about 7.44 km/s, ACS3 flies in low Earth orbit at an altitude of roughly 864 × 946 km, completing one revolution every 102.9 minutes — about 14.0 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0056). Its 97.3° retrograde, near-polar inclination is characteristic of a Sun-synchronous orbit — the type Earth-imaging and weather satellites use to revisit each spot at the same local solar time. Its orbital plane crosses the equator northbound at right ascension 185.7°. Earth's equatorial bulge drifts that plane eastward about 0.79° per day.

About the Other Active Satellites group
ACS3 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 ACS3 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, ACS3 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 the “When can I see it?” panel in the live view for when it is above your horizon and sunlit.
