PROBA-3 OSC — Live Satellite Tracking (NORAD 62258)
Track PROBA-3 OSC (NORAD catalog number 62258) 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 2024's 233rd orbital launch (COSPAR designation 2024-233C). 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 762 revolutions of Earth.
Its speed swings from 1.10 km/s at apogee to 9.84 km/s at perigee. PROBA-3 OSC follows a highly elliptical orbit, completing a revolution every 19.7 hours. The orbit is strongly elliptical (eccentricity 0.7996): each revolution swings from 1,040 km at perigee out to 60,180 km at apogee. Inclined 59.8° to the equator, it overflies every latitude up to about 60° north and south. Its orbital plane crosses the equator northbound at right ascension 91.9°. Earth's equatorial bulge drifts that plane westward about 0.08° per day.

About the Other Active Satellites group
PROBA-3 OSC 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 PROBA-3 OSC from the ground?
Not with the naked eye. At its altitude PROBA-3 OSC 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.
