NAVSTAR 78 (USA 293) — Live Satellite Tracking (NORAD 44506)
Track NAVSTAR 78 (USA 293) (NORAD catalog number 44506) 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 2019, launched on the 56th orbital launch of that year (COSPAR designation 2019-056A). As of this element set it had completed roughly 5,259 revolutions of Earth.
Moving at about 3.90 km/s, NAVSTAR 78 (USA 293) operates in medium Earth orbit at roughly 20,011–20,366 km altitude, taking about 12.0 hours per revolution (2.01 orbits a day). The orbit is essentially circular (eccentricity 0.0067). Inclined 55.6° to the equator, it overflies every latitude up to about 56° north and south. Its orbital plane crosses the equator northbound at right ascension 326.1°.

About the Navigation group
NAVSTAR 78 (USA 293) is part of the US GPS (NAVSTAR) fleet — one of 156 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 78 (USA 293) from the ground?
Not with the naked eye. At its altitude NAVSTAR 78 (USA 293) 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 the “When can I see it?” panel in the live view.
