11 sie 2010 · The idea behind a communications satellite is simple: send a signal into space, and send it back down to another spot on the globe. In NASA’s early days, engineers discovered the easiest way to accomplish this: bounce signals off a giant metal balloon floating in orbit.
30 lis 2010 · On April 6, 1965 COMSAT’s first satellite, EARLY BIRD, was launched from Cape Canaveral. Global satellite communications had begun. The Global Village: International Communications. Some glimpses of the Global Village had already been provided during experiments with TELSTAR, RELAY, and SYNCOM.
23 mar 2008 · Echo, NASA’s first communications satellite, was a passive spacecraft based on a balloon design created by an engineer at the Langley Research Center. Made of Mylar, the satellite measured 100 feet (30 meters) in diameter.
The Early Bird satellite was the first to provide direct and nearly instantaneous contact between Europe and North America, handling television, telephone, and telefacsimile transmissions. It was fairly small, measuring nearly 76 cm × 61 cm (2.5 ft × 2.0 ft) and weighing 34.5 kg (76 lb).
1 lis 2011 · In the era of high-speed communication, large-capacity broadband and multimedia personalization, satellite communication has become one of the most special ways of wireless communication.
This paper attempts to explain the “fil rouge” of the evolution of satellite technologies across six decades, analyzing successes and failures of past satellite missions, and concluding with a picture of future satellite communications.
