USA 164 (MILSTAR-2 3) — Live Satellite Tracking (NORAD 27168)
Track USA 164 (MILSTAR-2 3) (NORAD catalog number 27168) 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 2002, launched on the 1st orbital launch of that year (COSPAR designation 2002-001A).
Moving at about 3.10 km/s, USA 164 (MILSTAR-2 3) flies a geosynchronous orbit roughly 35,786 km up: its 23.9-hour period matches Earth's rotation, but at 11.3° inclination it is not geostationary — seen from the ground it traces a daily figure-eight around a fixed longitude, swinging about 11° north and south of the equator. The orbit is essentially circular (eccentricity 0.0098). Its 11.3° inclination keeps its ground track over the tropics and lower mid-latitudes. Its orbital plane crosses the equator northbound at right ascension 21.4°.

Can you see USA 164 (MILSTAR-2 3) from the ground?
Not with the naked eye. At its altitude USA 164 (MILSTAR-2 3) 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.
