TELKOM 3S

TELKOM 3S is an active satellite operated by PT Telkomunikasi (Indonesia), launched on 2017-02-14 from Guiana Space Centre, Kourou. It orbits in Geostationary Orbit (GEO) at altitudes between 35,778 km and 35,796 km with an inclination of 0.0°. It travels at approximately 11,070 km/h (3.07 km/s), completing one full orbit every ~24 hours (geosynchronous) — that’s roughly 1.00 orbits per day. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks TELKOM 3S in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

TELKOM 3S occupies geostationary orbit at approximately 35,786 km above the equator, where its orbital period matches the Earth’s 24-hour rotation. From the ground, it appears to hover over a fixed point — ideal for broadcast television, weather monitoring and wideband communications. Within ±50 km of TELKOM 3S’s average altitude, there are currently 713 active payloads and 58 tracked debris or rocket body fragments — notable neighbours include ASTRA 1N, GOES 16, TDRS 13. Indonesia operates approximately 17 active satellites in total, of which 10 share a similar altitude band with TELKOM 3S.
