A geostationary orbit (GEO) is a specific type of orbit characterized by a period matching the Earth's rotational period, resulting in a satellite that appears fixed relative to an observer on the ground. To achieve this stable position, the orbital radius must be approximately 42,164 kilometers directly above the equator, and the orbital inclination must be zero. Satellites placed in this high-altitude, stable orbit are invaluable for continuous communication and meteorological monitoring because their relative position does not change noticeably over time, allowing for sustained data relay and broadcast coverage across a large geographical region.
