GNSS satellites (GPS, Galileo, GLONASS, Beidou, etc) are not in geostationary orbits. Being in a geostationary orbit would put them in fixed "locations" in the sky, making them easily blocked by terrain and entirely unusable at high latitudes.

GPS satellites are in MEO, at ~20 km MSL. Other GNSS satellites use similar orbits.

(Just noticed a minor error: GNSS orbits are roughly 20k km, not 20 km!)
