IRIDIUM 113 — Live Satellite Tracking (NORAD 42803)
Track IRIDIUM 113 (NORAD catalog number 42803) 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 2017, launched on the 39th orbital launch of that year (COSPAR designation 2017-039A). It went up together with 9 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 48,288 revolutions of Earth.
Moving at about 7.47 km/s, IRIDIUM 113 flies in low Earth orbit at an altitude of roughly 783 × 786 km, completing one revolution every 100.4 minutes — about 14.3 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0002). Inclined 86.4° — nearly pole-to-pole — its ground track sweeps essentially every latitude. Its orbital plane crosses the equator northbound at right ascension 288.1°. Earth's equatorial bulge drifts that plane westward about 0.42° per day.

About the Other Active Satellites group
IRIDIUM 113 is one of 80 Iridium NEXT satellites in the WatchSat catalog. The constellation flies near-polar orbits around 780 km, inclined about 86°, providing global voice and data coverage. Browse all other active satellites live in 3D.
Can you see IRIDIUM 113 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, IRIDIUM 113 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.
