History

A communication Satellite is  an artificial satellite used to aid telecommunications, as by reflecting or relaying a radio signal. The first communication satellite was launched by the Soviets called Sputnik 1 on Octorober 4, 1957. America soon followed with project Score in 1958 during the race for space. These satellites just were for simple radio communications. The way a communication satellite works is like bouncing messages off a mirror in space to either a spead or fixed location. There are various patterns of orbit that the satellite rotates with or around the Earth. AT&T was the first company to put an active relay satellite (back then owned by Telstar) which NASA launched on July 10, 1962.

 

 

Billion dollar industry

 "Satellite communications is also the only truly commercial space technology- -generating billions of dollars annually in sales of products and services." (NASA) By 1964 there were 6 satellites total 2 of which were AT&T. This set up the telephone industry to be capable of long distance phone calls. Instead of using the typical land line people would be using the service of a geostationary satellite.
