COSMOS 2477 [GLONASS-M] — Live Satellite Tracking (NORAD 37868)
Track COSMOS 2477 [GLONASS-M] (NORAD catalog number 37868) 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 B of 2011's 64th orbital launch (COSPAR designation 2011-064B). It went up together with 2 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 11,547 revolutions of Earth.
Moving at about 3.96 km/s, COSMOS 2477 [GLONASS-M] operates in medium Earth orbit at roughly 19,088–19,186 km altitude, taking about 11.3 hours per revolution (2.13 orbits a day). The orbit is essentially circular (eccentricity 0.0019). Inclined 65.3° to the equator, it overflies every latitude up to about 65° north and south. Its orbital plane crosses the equator northbound at right ascension 70.2°.

About the Navigation group
COSMOS 2477 [GLONASS-M] is part of Russia's GLONASS 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 COSMOS 2477 [GLONASS-M] from the ground?
Not with the naked eye. At its altitude COSMOS 2477 [GLONASS-M] 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.
