BEIDOU-3 M4 — Live Satellite Tracking (NORAD 43207)
Track BEIDOU-3 M4 (NORAD catalog number 43207) 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 has been on orbit since 2018, launched on the 18th orbital launch of that year (COSPAR designation 2018-018A). 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 5,822 revolutions of Earth.
Moving at about 3.78 km/s, BEIDOU-3 M4 operates in medium Earth orbit at roughly 21,518–21,553 km altitude, taking about 12.9 hours per revolution (1.86 orbits a day). The orbit is essentially circular (eccentricity 0.0006). Inclined 56.7° to the equator, it overflies every latitude up to about 57° north and south. Its orbital plane crosses the equator northbound at right ascension 60.5°.

About the Navigation group
BEIDOU-3 M4 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 M4 from the ground?
Not with the naked eye. At its altitude BEIDOU-3 M4 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.
