GALAXY 13 (HORIZONS-1) — Live Satellite Tracking (NORAD 27954)
Track GALAXY 13 (HORIZONS-1) (NORAD catalog number 27954) 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 2003, launched on the 44th orbital launch of that year (COSPAR designation 2003-044A). As of this element set it had completed roughly 4,739 revolutions of Earth.
Moving at about 3.08 km/s, GALAXY 13 (HORIZONS-1) sits in the geostationary belt roughly 35,786 km above the equator, where its 23.9-hour orbit matches Earth's rotation — seen from the ground it stays parked over the same longitude around the clock. The orbit is essentially circular (eccentricity 0.0002). Its near-equatorial 1.6° inclination keeps it above the tropics at all times. Its orbital plane crosses the equator northbound at right ascension 82.7°.

GALAXY 13 (HORIZONS-1) 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 GALAXY 13 (HORIZONS-1) from the ground?
Not with the naked eye. At its altitude GALAXY 13 (HORIZONS-1) 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.
