TDRS 7 — Live Satellite Tracking (NORAD 23613)
Track TDRS 7 (NORAD catalog number 23613) 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 is object B of 1995's 35th orbital launch (COSPAR designation 1995-035B). As of this element set it had completed roughly 11,406 revolutions of Earth.
Moving at about 3.08 km/s, TDRS 7 flies a geosynchronous orbit roughly 35,786 km up: its 23.9-hour period matches Earth's rotation, but at 13.3° inclination it is not geostationary — seen from the ground it traces a daily figure-eight around a fixed longitude, swinging about 13° north and south of the equator. The orbit is essentially circular (eccentricity 0.0012). Its 13.3° inclination keeps its ground track over the tropics and lower mid-latitudes. Its orbital plane crosses the equator northbound at right ascension 347.6°.

About the Other Active Satellites group
TDRS 7 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 TDRS 7 from the ground?
Not with the naked eye. At its altitude TDRS 7 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.
