ONEWEB-0397 — Live Satellite Tracking (NORAD 50477)
Track ONEWEB-0397 (NORAD catalog number 50477) 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 J of 2021's 132nd orbital launch (COSPAR designation 2021-132J). It went up together with 35 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 23,236 revolutions of Earth.
Moving at about 7.26 km/s, ONEWEB-0397 flies in low Earth orbit at an altitude of roughly 1,195 × 1,199 km, completing one revolution every 109.2 minutes — about 13.2 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0002). Inclined 87.9° — nearly pole-to-pole — its ground track sweeps essentially every latitude. Its orbital plane crosses the equator northbound at right ascension 319.3°. Earth's equatorial bulge drifts that plane westward about 0.20° per day.

About the OneWeb group
ONEWEB-0397 is one of 651 OneWeb (Eutelsat OneWeb) broadband satellites tracked here. The constellation serves internet from near-polar orbits at roughly 1,200 km — about twice Starlink's altitude — where atmospheric drag is minimal and each satellite covers a wide swath. Watch the OneWeb constellation live in 3D.
Can you see ONEWEB-0397 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, ONEWEB-0397 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 for when it is above your horizon and sunlit.
