📖 About This Object
THAICOM 4 is an active satellite operated by Thailand, launched on 2005-08-11 from Guiana Space Centre, Kourou. With over 21 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 35,780 km and 35,796 km with an inclination of 0.0°. It travels at approximately 11,069 km/h (3.07 km/s), completing one full orbit every ~24 hours (geosynchronous) — that’s roughly 1.00 orbits per day. It is part of the Geo Protected constellation group. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks THAICOM 4 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
THAICOM 4 occupies geostationary orbit (GEO) at approximately 35,786 km above the equator. At this precise altitude, the satellite’s orbital period matches the Earth’s rotation — so it appears to hover over a fixed point on the equator. GEO is used primarily for broadcast television, weather monitoring (Meteosat, GOES) and wideband communications. Only about 560 active satellites occupy the GEO belt, but its commercial value is immense: a single GEO slot can cover roughly one-third of the Earth’s surface.
THAICOM 4 orbits at approximately 35,788 km altitude, where the orbital period matches the Earth’s 24-hour rotation. This means it stays above the same point on the equator at all times. Its actual speed is still 11,069 km/h — it just keeps pace with the ground below.
THAICOM 4 is operated by Thailand. It is catalogued by the U.S. Space Surveillance Network under NORAD ID 28786. You can track THAICOM 4 in real time on Orbital Radar’s live tracker.
THAICOM 4 was launched on 2005-08-11 from Guiana Space Centre, Kourou, the European spaceport in French Guiana, chosen for its equatorial location which provides an energy-efficient boost for orbital insertions.
Yes — Orbital Radar tracks THAICOM 4 (NORAD ID 28786) using the latest TLE (two-line element set) data from Space-Track and CelesTrak. Open the live tracker to see its current position, altitude, speed and orbital path updated in real time.
THAICOM 4 travels at approximately 11,069 km/h (6,878 mph) — roughly 3.07 km/s. Despite this high speed, it appears stationary from the ground because it matches the Earth’s rotation. Geostationary satellites are actually slower than LEO satellites because orbital velocity decreases with altitude.
THAICOM 4 is a member of the Geo Protected constellation. Satellites in this group work together to provide coordinated coverage, typically in similar orbital planes at comparable altitudes. You can view all Geo Protected satellites on Orbital Radar’s live tracker.
