SJ 16-02 — Live Satellite Tracking (NORAD 41634)
Track SJ 16-02 (NORAD catalog number 41634) 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 2016, launched on the 43rd orbital launch of that year (COSPAR designation 2016-043A). As of this element set it had completed roughly 55,339 revolutions of Earth.
Moving at about 7.57 km/s, SJ 16-02 flies in low Earth orbit at an altitude of roughly 588 × 599 km, completing one revolution every 96.4 minutes — about 14.9 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0008). Inclined 75.0° to the equator, it overflies every latitude up to about 75° north and south. Its orbital plane crosses the equator northbound at right ascension 123.6°. Earth's equatorial bulge drifts that plane westward about 1.90° per day.

Can you see SJ 16-02 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, SJ 16-02 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.
