BEIDOU-2 IGSO-7 — Live Satellite Tracking (NORAD 43539)
Track BEIDOU-2 IGSO-7 (NORAD catalog number 43539) 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 2018, launched on the 57th orbital launch of that year (COSPAR designation 2018-057A). As of this element set it had completed roughly 3,004 revolutions of Earth.
Moving at about 3.11 km/s, BEIDOU-2 IGSO-7 flies a geosynchronous orbit roughly 35,786 km up: its 23.9-hour period matches Earth's rotation, but at 55.2° inclination it is not geostationary — seen from the ground it traces a daily figure-eight around a fixed longitude, swinging about 55° north and south of the equator. The orbit is essentially circular (eccentricity 0.0108). Inclined 55.2° to the equator, it overflies every latitude up to about 55° north and south. Its orbital plane crosses the equator northbound at right ascension 162.3°.

This page's orbital elements come from the CelesTrak catalog of 2026-09-17. The live 3D view above fetches its own current CelesTrak data when the page opens, through an edge cache that refreshes roughly every 30 minutes.
About the Navigation group
BEIDOU-2 IGSO-7 is part of China's BeiDou fleet — one of 173 global-navigation satellites in the WatchSat catalog across GPS, GLONASS, Galileo and BeiDou. GNSS spacecraft broadcast precise time signals from orbits around 20,000 km up; a phone fixes its position by comparing several of them at once. See the whole navigation group live in 3D.
Can you see BEIDOU-2 IGSO-7 from the ground?
Not with the naked eye. At its altitude BEIDOU-2 IGSO-7 is far beyond unaided visibility — following satellites this high takes a telescope and good timing. You can still track it precisely in the live 3D view above, or check pass predictions for your location are available on this page once you select the satellite and share your position.
