Satellite-based communication has become a major facet of the telecommunication industry for at least two major reasons. First, it provides a means of broadcasting information to a large number of people simultaneously. Thus, satellite communication systems are an important ingredient in the implementation of a global communication infrastructure. Second, satellite communication provides a means of reaching isolated places on earth, where terrestrial telecommunications infrastructure does not exist or teledensity is low. Applications of satellite communications include very small aperture terminals (VSATs) for business applications; fixed satellite service (FSS), which interconnects fixed points; mobile satellite (MSAT) service, which employs satellite to extend cellular network to mobile units; satellite radio, which continuously provide entertainment to listeners; and satellite-based Internet, which enables IP-over-satellite connectivity.
