Describing an object (typically a satellite) in geostationary orbit. From the ground, a geostationary satellite appears motionless in the sky — held at the same point above the equator. Distinct from 'geosynchronous' which has the same period but may have inclination, producing a figure-8 ground track. NOAA GOES and JMA Himawari are geostationary; some BeiDou and other GNSS satellites are geosynchronous-inclined.
In LaunchDetect
A satellite is fully geostationary only if its orbit is circular, equatorial (0° inclination), and at the exact GEO altitude.
