geostationary orbit satellite
/ ˌdʒiːoʊˈsteɪʃnri ˈɔːrbət ˈsætəˌlaɪt /
A communications satellite that rotates with the earth and thus appears to remain fixed, or stationary, over a particular location. This travels in orbit 22,282 miles above the equator, where its period of rotation matches the earth’s rotation. The service area, or footprint, of the satellite is approximately one-third of the earth’s surface, so global satellite coverage can be achieved with three satellites in orbit. In a voice communication system, a round-trip to and from this satellite takes approximately 250 milliseconds. Satellite-based data communications are necessary for delivering high bandwidth options to rural areas. Acronym: GEO.
