Circular Satellite Orbit 2 2 e Gm m mv rr Where v is the orbital velocity of the satellite. mv 2 /r is the centripital force required to keep the satellite in a circular orbit. Assuming that the earth is a sphere, we can treat it as a point mass.
Radius for a Satellite in Geostationary/Geosynchronous Orbit 2 T  Where T is the period of the satellite. Therefore, The satellite in geostationary orbit has the same angular velocity as the earth. The angular velocity of a satellite is, 2 r T v 3 2 e Gm r Inserting the angular velocity of the Earth, r=42,164 km, or 35,786 km above the Earth’s surface. 2 23 4 e Tr
