About JCSAT 1
JCSAT 1 is a satellite from Japan, launched on Mar 6, 1989 from French Guiana.
It sits in geostationary orbit about 35,800 km above the equator near 100°E, turning with Earth so it stays over the same spot.
The map shows where it is right now; the pass list tells you when it next comes over your location.

Orbit height over the past year
Over the last 16 days its lowest point went from 35,975 km to 35,977 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
