History[ edit ] The concept of the geostationary orbit was originated by Russian theorist Konstantin Tsiolkovsky , who wrote articles on space travel around the beginning of the 20th century. On April 6, , the first commercial satellite was launched into space, Intelsat I , nicknamed Early Bird. These enterprise terminals made up the vast majority of sites for the next 20 years for two-way data or telephony applications.

Postal Service in the s. ViaSat launched the highest capacity satellite ever, ViaSat-1, in to expand the WildBlue base under its Exede brand. By September , Hughes became the first Satellite Internet Provider to surpass one million active terminals. Some VSAT networks are configured by having several centralized uplink sites and VSAT stemming from it connected in a multi-star topology with each star and each terminal in each star connected to each other in a mesh topology.

Others configured in only a single-star topology sometimes will have each terminal connected to each other as well, resulting in each terminal acting as a central hub. These configurations are utilized to minimize the overall cost of the network, and to alleviate the amount of data that has to be relayed through a central uplink site or sites of a star or multi-star network.

Future applications[ edit ] Advances in technology have dramatically improved the price—performance ratio of fixed satellite service FSS over the past five years. New VSAT systems are coming online using Ka band technology that promise higher data rates for lower costs. FSS systems currently in orbit have a huge capacity with a relatively low price structure. FSS systems provide various applications for subscribers, including: telephony , fax , television , high-speed data communication services, Internet access, satellite news gathering SNG , Digital Audio Broadcasting DAB and others.

These systems provide high-quality service because they create efficient communication systems for both residential and business users. Constituent parts of a VSAT configuration[ edit ].
