SUMMARY
Geostationary satellites maintain a fixed position relative to the Earth's surface by orbiting at the same rotational speed as the Earth. This requires them to be positioned at an orbital radius of approximately 35,786 kilometers above the equator. The synchronization of their orbital period with the Earth's rotation allows them to appear stationary to an observer on the ground. The slight difference in time for a satellite's revolution compared to the Earth's rotation is negligible, typically only about a minute.
