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 2,991 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 162.4°.

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.
