📖 About This Object
TURKSAT 4B is an active satellite operated by Turksat (Turkey), launched on 2015-10-16 from Baikonur, Kazakhstan. After 11 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Geostationary Orbit (GEO) at altitudes between 35,777 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 TURKSAT 4B in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
TURKSAT 4B 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 TURKSAT 4B’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. Turkey operates approximately 41 active satellites in total, of which 7 share a similar altitude band with TURKSAT 4B.
❓ Frequently Asked Questions
TURKSAT 4B orbits at approximately 35,786 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.
TURKSAT 4B is operated by Turksat (Turkey). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 40984. You can track TURKSAT 4B in real time on Orbital Radar’s live tracker or browse all operators in the operator directory.
TURKSAT 4B was launched on 2015-10-16 from Baikonur, Kazakhstan, the world’s first and largest operational space launch facility, located in Kazakhstan. View the full satellite launch log.
Yes — Orbital Radar tracks TURKSAT 4B (NORAD ID 40984) 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.
TURKSAT 4B 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.
