YAOGAN-40 01C — Live Satellite Tracking (NORAD 57833)
Track YAOGAN-40 01C (NORAD catalog number 57833) 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 D of 2023's 139th orbital launch (COSPAR designation 2023-139D). 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 15,439 revolutions of Earth.
Moving at about 7.43 km/s, YAOGAN-40 01C flies in low Earth orbit at an altitude of roughly 856 × 860 km, completing one revolution every 101.9 minutes — about 14.1 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0002). Inclined 86.0° — nearly pole-to-pole — its ground track sweeps essentially every latitude. Its orbital plane crosses the equator northbound at right ascension 222.4°. Earth's equatorial bulge drifts that plane westward about 0.45° per day.

Can you see YAOGAN-40 01C from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, YAOGAN-40 01C 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.
