NAVSTAR 86 (USA 585) — Live Satellite Tracking (NORAD 68791)
Track NAVSTAR 86 (USA 585) (NORAD catalog number 68791) 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 2026, launched on the 87th orbital launch of that year (COSPAR designation 2026-087A). As of this element set it had completed roughly 246 revolutions of Earth.
Moving at about 3.88 km/s, NAVSTAR 86 (USA 585) operates in medium Earth orbit at roughly 20,132–20,244 km altitude, taking about 12.0 hours per revolution (2.01 orbits a day). The orbit is essentially circular (eccentricity 0.0021). Inclined 55.0° to the equator, it overflies every latitude up to about 55° north and south. Its orbital plane crosses the equator northbound at right ascension 204.6°.

About the Navigation group
NAVSTAR 86 (USA 585) is part of the US GPS (NAVSTAR) 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 NAVSTAR 86 (USA 585) from the ground?
Not with the naked eye. At its altitude NAVSTAR 86 (USA 585) 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.
