GLOBALSTAR M077 — Live Satellite Tracking (NORAD 37191)
Track GLOBALSTAR M077 (NORAD catalog number 37191) 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 2010's 54th orbital launch (COSPAR designation 2010-054D). It went up together with 5 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 73,066 revolutions of Earth.
Moving at about 6.97 km/s, GLOBALSTAR M077 flies in low Earth orbit at an altitude of roughly 1,835 × 1,839 km, completing one revolution every 123.3 minutes — about 11.7 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0002). Inclined 52.0° to the equator, it overflies every latitude up to about 52° north and south. Its orbital plane crosses the equator northbound at right ascension 332.3°. Earth's equatorial bulge drifts that plane westward about 2.54° per day.

Can you see GLOBALSTAR M077 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, GLOBALSTAR M077 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.
