BNU-1 (JINGSHI 1) — Live Satellite Tracking (NORAD 44529)
Track BNU-1 (JINGSHI 1) (NORAD catalog number 44529) 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 59th orbital launch (COSPAR designation 2019-059B). It went up together with 2 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 36,887 revolutions of Earth.
Moving at about 7.50 km/s, BNU-1 (JINGSHI 1) flies in low Earth orbit at an altitude of roughly 728 × 748 km, completing one revolution every 99.4 minutes — about 14.5 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0014). Its 98.6° 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 20.9°. Earth's equatorial bulge precesses that plane eastward about 1.02° per day, matching the Sun's apparent motion — which is what holds its lighting constant.

About the Other Active Satellites group
BNU-1 (JINGSHI 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 BNU-1 (JINGSHI 1) from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, BNU-1 (JINGSHI 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.
