USA 115 (MILSTAR-1 2) — Live Satellite Tracking (NORAD 23712)

Track USA 115 (MILSTAR-1 2) (NORAD catalog number 23712) 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 1995, launched on the 60th orbital launch of that year (COSPAR designation 1995-060A).

Moving at about 3.08 km/s, USA 115 (MILSTAR-1 2) flies a geosynchronous orbit roughly 35,786 km up: its 23.9-hour period matches Earth's rotation, but at 14.1° inclination it is not geostationary — seen from the ground it traces a daily figure-eight around a fixed longitude, swinging about 14° north and south of the equator. The orbit is essentially circular (eccentricity 0.0006). Its 14.1° inclination keeps its ground track over the tropics and lower mid-latitudes. Its orbital plane crosses the equator northbound at right ascension 3.1°.

About the Other Active Satellites group

USA 115 (MILSTAR-1 2) is one of 4,471 active satellites in WatchSat's general catalog — the broad population of Earth-observation, communications, science, amateur-radio and technology spacecraft outside the giant broadband constellations. Browse all other active satellites live in 3D.

Can you see USA 115 (MILSTAR-1 2) from the ground?

Not with the naked eye. At its altitude USA 115 (MILSTAR-1 2) 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.
