TELKOM 4 (MERAH PUTIH) — Live Satellite Tracking (NORAD 43587)
Track TELKOM 4 (MERAH PUTIH) (NORAD catalog number 43587) 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 2018, launched on the 64th orbital launch of that year (COSPAR designation 2018-064A). As of this element set it had completed roughly 2,970 revolutions of Earth.
Moving at about 3.07 km/s, TELKOM 4 (MERAH PUTIH) 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 0.0001). Its near-equatorial 0.0° inclination keeps it above the tropics at all times. Its orbital plane crosses the equator northbound at right ascension 117.1°.

About the Other Active Satellites group
TELKOM 4 (MERAH PUTIH) 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 TELKOM 4 (MERAH PUTIH) from the ground?
Not with the naked eye. At its altitude TELKOM 4 (MERAH PUTIH) 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.
