LEO 1 (LEO VANTAGE 1) — Live Satellite Tracking (NORAD 43113)

Track LEO 1 (LEO VANTAGE 1) (NORAD catalog number 43113) 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 2018's 4th orbital launch (COSPAR designation 2018-004C). 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 44,952 revolutions of Earth.

Its speed swings from 7.26 km/s at apogee to 7.79 km/s at perigee. LEO 1 (LEO VANTAGE 1) flies in low Earth orbit at an altitude of roughly 428 × 919 km, completing one revolution every 98.1 minutes — about 14.7 trips around Earth per day. The orbit is mildly elliptical (eccentricity 0.0348), so its altitude varies between 428 km and 919 km over each revolution. Its 99.2° 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 179.3°. Earth's equatorial bulge drifts that plane eastward about 1.13° per day.

About the Other Active Satellites group

LEO 1 (LEO VANTAGE 1) 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 LEO 1 (LEO VANTAGE 1) from the ground?

Sometimes. Like most low-Earth-orbit spacecraft, LEO 1 (LEO VANTAGE 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 for when it is above your horizon and sunlit.
