A brief history of space communication ! The idea of radio transmission through space was first conceived in 1911.In 1945, Arthur C. Clarke proposed the idea of using earth-orbiting satellite as a relay point for communication between two earth stations.This idea later led to the great success of satellite communications.In 1957, the Soviet Union launched Sputnik I , which transmitted telemetry signals for 21 days.In 1958, United States launched Explorer I, which transmitted telemetry signals for 5 months.

In July 1964, INTELSAT, a multinational organization, was formed with the purpose to design, develop, construct, establish, and maintain the operation of the space segment of a global commercial communications satellite system. In April 1965, Early Bird (INTELSAT I), a geostationary communications satellite was launched. In a span of seven years, four generations of satellites – INTELSAT I through IV were launched and placed in commercial operation. (more…)
