KOREASAT 1

KOREASAT 1 is an active satellite operated by South Korea, launched on 1995-08-05 from Cape Canaveral, Florida. With over 31 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 35,947 km and 35,964 km with an inclination of 14.7°. It travels at approximately 11,048 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 KOREASAT 1 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

KOREASAT 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 14.7°, 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 KOREASAT 1’s average altitude, there are currently 60 active payloads and 20 tracked debris or rocket body fragments. South Korea operates approximately 51 active satellites in total, of which 2 share a similar altitude band with KOREASAT 1.
