The first Internet-ready satellite for consumers was launched in September 2003. and Globalstar, dampened marketplace enthusiasm for satellite Internet development. Teledesic's failure, coupled with the bankruptcy filings of the satellite communications providers Iridium Communications Inc. Teledesic's idea was to create a broadband satellite constellation of hundreds of low-orbiting satellites in the K a-band frequency, providing inexpensive Internet access with download speeds of up to 720 Mbit/s. Among those were EchoStar, Lockheed Martin, GE-Americom, Motorola and KaStar Satellite, which later became WildBlue.Īmong prominent aspirants in the early-stage satellite Internet sector was Teledesic, an ambitious and ultimately failed project funded in part by Microsoft that ended up costing more than $9 billion. In 1995, the FCC issued a call for more K a-band satellite applications, attracting applications from 15 companies. filed with the Federal Communications Commission for a license to launch the first K a-band satellite, Spaceway. Following the invention of the Internet and the World Wide Web, geostationary satellites attracted interest as a potential means of providing Internet access.Ī significant enabler of satellite-delivered Internet has been the opening up of the K a band for satellites. Succeeding generations of communications satellites featuring larger capacities and improved performance characteristics were adopted for use in television delivery, military applications and telecommunications purposes. The first satellite to successfully reach geostationary orbit was Syncom3, built by Hughes Aircraft for NASA and launched on August 19, 1963. Clarke in a paper in Wireless World in 1945. The idea of a geosynchronous satellite-one that could orbit the Earth above the equator and remain fixed by following the Earth's rotation-was first proposed by Herman Potočnik in 1928 and popularised by the science fiction author Arthur C. The first commercial communications satellite was Telstar 1, built by Bell Labs and launched in July 1962. In addition, new satellite internet constellations are being developed in low-earth orbit to enable low-latency internet access from space.įollowing 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. 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 K u band to achieve downstream data speeds up to 506 Mbit/s. Satellite Internet access is Internet access provided through communication satellites. Internet access provided through communication satellites
