Geostationary Satellite Orbit Earth Tv Remains Fixed Position

word geostationary
definition Being or having an orbit such that a satellite remains in a fixed position above the Earth, especially having such an orbit above the equator.
eg_sentence It was the science-fiction writer Arthur C. Clarke who first conceived of a set of geostationary satellites as a means of worldwide communication.
explanation We don't give much thought to geostationary satellites, but many of us rely on them daily. Anyone who watches satellite TV or listens to satellite radio is dependent on them; the weather photos you see on TV are taken from geostationary satellites; and military information gathering via satellite goes on quietly day after day. (Though the satellites that provide GPS service for your car or cell phone actually aren't geostationary, since they orbit the Earth twice a day.) By 2009 there were about 300 geostationary satellites in operation, all of them moving at an altitude of about 22,000 miles. Since they hover above the same spot on Earth, your receiving dish or antenna doesn't have to turn in order to track them.
