Satellite Internet access Satellite Internet access Satellite Internet access is Internet access provided through communications satellites. Modern consumer grade satellite Internet service is typically provided to individual users through geostationary satellites that can offer relatively high data speeds, with newer satellites using to achieve downstream data speeds up to 506 Mbps. Following the launch of the first satellite, Sputnik 1, by the Soviet Union in October 1957, the US successfully launched the Explorer 1 satellite in 1958. The first commercial communications satellite was Telstar 1, built by Bell Labs and launched in July 1962. The idea of a geosynchronous satellite—one that could orbit
Eurostar (satellite bus) orbit. The Eurostar spacecraft series is designed for a variety of telecommunications needs including fixed services and broadcast, mobile services, broadband and secured communications. Eurostar was designed in the mid 1980s jointly by Matra Marconi Space and BAe (under the "United Satellite" venture, now integrated within Airbus Defence and Space) to an internally developed specification, for a market which at the time had a design envelope of 1.8-2.5 Tons on the proposed launch vehicles (STS PAM D2 and Ariane 4). Satellite payload power was from 1300 to 2600 W. This was the first commercial satellite to have a digital avionics
