BEIDOU-3 M20 — Live Satellite Tracking (NORAD 44865)
Track BEIDOU-3 M20 (NORAD catalog number 44865) 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 2019's 90th orbital launch (COSPAR designation 2019-090B). 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 4,592 revolutions of Earth.
Moving at about 3.78 km/s, BEIDOU-3 M20 operates in medium Earth orbit at roughly 21,499–21,572 km altitude, taking about 12.9 hours per revolution (1.86 orbits a day). The orbit is essentially circular (eccentricity 0.0013). Inclined 56.6° to the equator, it overflies every latitude up to about 57° north and south. Its orbital plane crosses the equator northbound at right ascension 59.8°.

About the Navigation group
BEIDOU-3 M20 is part of China's BeiDou fleet — one of 173 global-navigation satellites in the WatchSat catalog across GPS, GLONASS, Galileo and BeiDou. GNSS spacecraft broadcast precise time signals from orbits around 20,000 km up; a phone fixes its position by comparing several of them at once. See the whole navigation group live in 3D.
Can you see BEIDOU-3 M20 from the ground?
Not with the naked eye. At its altitude BEIDOU-3 M20 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 are available on this page once you select the satellite and share your position.
