Earth satellites are typically more than 100-km high so as to mainly be above the Earth's atmosphere. This is because the atmosphere scatters and absorbs electromagnetic radiation, including radio waves, which are used to communicate with the satellite. Therefore, by being above the atmosphere, the satellite's signals can be transmitted with minimal interference.

Although the Earth's gravitational influence does play a role in maintaining the orbit of the satellite, the primary reason for the height of the satellite is to avoid atmospheric interference.
