📖 About This Object
JCSAT 6 is an active satellite operated by SKY Perfect JSAT (Japan), launched on 1999-02-16 from Cape Canaveral, Florida. With over 27 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 36,101 km and 36,303 km with an inclination of 9.7°. It travels at approximately 11,016 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 JCSAT 6 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
JCSAT 6 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 9.7°, 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 JCSAT 6’s average altitude, there are currently 103 active payloads and 15 tracked debris or rocket body fragments. Japan operates approximately 189 active satellites in total, of which 9 share a similar altitude band with JCSAT 6.
❓ Frequently Asked Questions
JCSAT 6 orbits at approximately 36,202 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 11,016 km/h — it just keeps pace with the ground below. With an inclination of 9.7°, it actually traces a small figure-of-eight pattern rather than remaining perfectly fixed. Learn more about geostationary orbits.
JCSAT 6 is operated by SKY Perfect JSAT (Japan). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 25630. You can track JCSAT 6 in real time on Orbital Radar’s live tracker or browse all operators in the operator directory.
JCSAT 6 was launched on 1999-02-16 from Cape Canaveral, Florida, one of the busiest launch facilities in the world, operated by NASA and the U.S. Space Force on Florida’s Atlantic coast. View the full satellite launch log.
Yes — Orbital Radar tracks JCSAT 6 (NORAD ID 25630) 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.
JCSAT 6 travels at approximately 11,016 km/h (6,845 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.
