A satellite in a geostationary orbit will remain fixed above one location on the equator of the Earth. GEO is achieved by placing the satellite at an altitude where its orbital period is equal to the length of one day and giving it an inclination value of 0 degrees.
Geostationary satellite’s have an altitude value of approximately 36,000 km or 22,200 miles. These satellites can “see” about 70 degrees north and south of the equator.
Common Uses and Benefits: Communication coverage over a fixed area and, communication between satellites. Ground stations can use fixed direction antennas instead of tracking antennas.
