📖 About This Object
GSAT 12 is an active satellite operated by Indian Space Research Organization (ISRO) (India), launched on 2011-07-15 from SRI. After 15 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Geostationary Orbit (GEO) at altitudes between 36,167 km and 36,206 km with an inclination of 5.3°. It travels at approximately 11,018 km/h (3.06 km/s), completing one full orbit every 24.3 hours — that’s roughly 0.99 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 GSAT 12 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
GSAT 12 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. With an inclination of 5.3°, it traces a small figure-of-eight pattern relative to the equator rather than remaining perfectly stationary, which can indicate aging stationkeeping fuel or a deliberate inclined-orbit strategy. Within ±50 km of GSAT 12’s average altitude, there are currently 131 active payloads and 12 tracked debris or rocket body fragments. India operates approximately 108 active satellites in total.
🔗 Galileo Navigation Constellation
This satellite is part of Galileo, the European Union's global navigation satellite system. Galileo provides high-accuracy positioning independent of GPS, GLONASS and BeiDou. The constellation operates at approximately 23,222 km altitude in three orbital planes with an inclination of 56°. Galileo offers multiple services including the Open Service (free, metre-level accuracy), High Accuracy Service (centimetre-level) and the Search and Rescue return-link service.
❓ Frequently Asked Questions
GSAT 12 orbits at approximately 36,187 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 11,018 km/h — it just keeps pace with the ground below. With an inclination of 5.3°, it actually traces a small figure-of-eight pattern rather than remaining perfectly fixed. Learn more about geostationary orbits.
GSAT 12 is operated by Indian Space Research Organization (ISRO) (India). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 37746. You can track GSAT 12 in real time on Orbital Radar’s live tracker or browse all operators in the operator directory.

Yes — Orbital Radar tracks GSAT 12 (NORAD ID 37746) 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. You can also browse the satellite directory to find other tracked objects.
GSAT 12 travels at approximately 11,018 km/h (6,846 mph) — roughly 3.06 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.
