📖 About This Object
JCSAT 2 is an active satellite operated by Japan, launched on 1990-01-01 from Cape Canaveral, Florida. With over 36 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 36,024 km and 36,536 km with an inclination of 15.9°. It travels at approximately 11,005 km/h (3.06 km/s), completing one full orbit every 24.4 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 2 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 2 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. This satellite has a non-zero inclination of 15.9°, meaning it traces a small figure-of-eight pattern relative to the ground rather than remaining perfectly stationary. This can indicate an aging satellite whose stationkeeping fuel is running low, or a deliberate inclined-orbit strategy to extend operational life.
❓ Frequently Asked Questions
JCSAT 2 orbits at approximately 36,280 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 11,005 km/h — it just keeps pace with the ground below. With an inclination of 15.9°, it actually traces a small figure-of-eight pattern rather than remaining perfectly fixed.
JCSAT 2 is operated by Japan. It is catalogued by the U.S. Space Surveillance Network under NORAD ID 20402. You can track JCSAT 2 in real time on Orbital Radar’s live tracker.
JCSAT 2 was launched on 1990-01-01 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.
Yes — Orbital Radar tracks JCSAT 2 (NORAD ID 20402) 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.
JCSAT 2 travels at approximately 11,005 km/h (6,838 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.
