📖 About This Object
GSAT 17 is an active satellite operated by Indian Space Research Organization (ISRO) (India), launched on 2017-06-28 from Guiana Space Centre, Kourou. It orbits in Geostationary Orbit (GEO) at altitudes between 35,779 km and 35,795 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 GSAT 17 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 17 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 GSAT 17’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. India operates approximately 108 active satellites in total, of which 36 share a similar altitude band with GSAT 17.
🔗 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 17 orbits at approximately 35,787 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 11,070 km/h — it just keeps pace with the ground below. Learn more about geostationary orbits.
GSAT 17 is operated by Indian Space Research Organization (ISRO) (India). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 42815. You can track GSAT 17 in real time on Orbital Radar’s live tracker or browse all operators in the operator directory.
GSAT 17 was launched on 2017-06-28 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. View the full satellite launch log.
Yes — Orbital Radar tracks GSAT 17 (NORAD ID 42815) 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 17 travels at approximately 11,070 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.
