TIANYAN 02 — Live Satellite Tracking (NORAD 44882)

Track TIANYAN 02 (NORAD catalog number 44882) 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 2019's 93rd orbital launch (COSPAR designation 2019-093D). It went up together with 7 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 36,496 revolutions of Earth.

Moving at about 7.60 km/s, TIANYAN 02 flies in low Earth orbit at an altitude of roughly 545 × 566 km, completing one revolution every 95.6 minutes — about 15.1 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0015). 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 345.9°. Earth's equatorial bulge precesses that plane eastward about 1.01° per day, matching the Sun's apparent motion — which is what holds its lighting constant.

About the Other Active Satellites group

TIANYAN 02 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 TIANYAN 02 from the ground?

Sometimes. Like most low-Earth-orbit spacecraft, TIANYAN 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.
