ZIYUAN 3-02 (ZY 3-02) — Live Satellite Tracking (NORAD 41556)
Track ZIYUAN 3-02 (ZY 3-02) (NORAD catalog number 41556) 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 33rd orbital launch of that year (COSPAR designation 2016-033A). As of this element set it had completed roughly 57,046 revolutions of Earth.
Moving at about 7.62 km/s, ZIYUAN 3-02 (ZY 3-02) flies in low Earth orbit at an altitude of roughly 500 × 519 km, completing one revolution every 94.7 minutes — about 15.2 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0013). Its 97.4° 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 324.4°. 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 ZIYUAN 3-02 (ZY 3-02) from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, ZIYUAN 3-02 (ZY 3-02) 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.
