BEIJING-3B — Live Satellite Tracking (NORAD 53587)
Track BEIJING-3B (NORAD catalog number 53587) 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 2022, launched on the 103rd orbital launch of that year (COSPAR designation 2022-103A). As of this element set it had completed roughly 21,929 revolutions of Earth.
Moving at about 7.57 km/s, BEIJING-3B flies in low Earth orbit at an altitude of roughly 596 × 633 km, completing one revolution every 96.8 minutes — about 14.9 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0026). Its 97.8° 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 326.3°. Earth's equatorial bulge precesses that plane eastward about 0.98° per day, matching the Sun's apparent motion — which is what holds its lighting constant.

Can you see BEIJING-3B from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, BEIJING-3B 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.
