PACE-1 — Live Satellite Tracking (NORAD 48909)
Track PACE-1 (NORAD catalog number 48909) 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 AG of 2021's 59th orbital launch (COSPAR designation 2021-059AG). It went up together with 11 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 29,229 revolutions of Earth.
Moving at about 7.77 km/s, PACE-1 flies in low Earth orbit at an altitude of roughly 237 × 242 km, completing one revolution every 89.2 minutes — about 16.2 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0004). Inclined 97.7° — nearly pole-to-pole — its ground track sweeps essentially every latitude. Its orbital plane crosses the equator northbound at right ascension 109.4°. Earth's equatorial bulge drifts that plane eastward about 1.17° per day.

About the Other Active Satellites group
PACE-1 is one of 4,464 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 PACE-1 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, PACE-1 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 are available on this page once you select the satellite and share your position for when it is above your horizon and sunlit.
