📖 About This Object
ASIASAT 1 is an active satellite operated by AsiaSat (AsiaSat (China/HK)), launched on 1990-04-07 from Xichang, China. With over 36 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 36,067 km and 36,088 km with an inclination of 14.9°. It travels at approximately 11,032 km/h (3.06 km/s), completing one full orbit every 24.2 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 ASIASAT 1 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
ASIASAT 1 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 14.9°, 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 ASIASAT 1’s average altitude, there are currently 140 active payloads and 13 tracked debris or rocket body fragments. AsiaSat (China/HK) operates approximately 8 active satellites in total.
❓ Frequently Asked Questions
ASIASAT 1 orbits at approximately 36,078 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 11,032 km/h — it just keeps pace with the ground below. With an inclination of 14.9°, it actually traces a small figure-of-eight pattern rather than remaining perfectly fixed. Learn more about geostationary orbits.
ASIASAT 1 is operated by AsiaSat (AsiaSat (China/HK)). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 20558. You can track ASIASAT 1 in real time on Orbital Radar’s live tracker or browse all operators in the operator directory.

Yes — Orbital Radar tracks ASIASAT 1 (NORAD ID 20558) 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.
ASIASAT 1 travels at approximately 11,032 km/h (6,855 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.
