ORBCOMM FM27 — Live Satellite Tracking (NORAD 25481)
Track ORBCOMM FM27 (NORAD catalog number 25481) 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 G of 1998's 53rd orbital launch (COSPAR designation 1998-053G).
Moving at about 7.47 km/s, ORBCOMM FM27 flies in low Earth orbit at an altitude of roughly 766 × 770 km, completing one revolution every 100.1 minutes — about 14.4 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0003). Inclined 45.0° to the equator, it overflies every latitude up to about 45° north and south. Its orbital plane crosses the equator northbound at right ascension 305.9°. Earth's equatorial bulge drifts that plane westward about 4.75° per day.

Can you see ORBCOMM FM27 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, ORBCOMM FM27 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.
