Invention of Communication Satellite

First communication satellite was introduced or launched by Telstar- active as in amplifying and retransmitting incoming signals, rather than passively bouncing them back to Telstar makes real a 1945 concept by science fiction author Arthur C. Clarke, who envisioned a global communications network based on geosynchronous satellites. Two weeks after Telstar's debut, President Kennedy holds a press conference in Washington, D.C., that is broadcast live across the Atlantic.

A communication system has a plurality of ground stations and a plurality of satellites located in a first orbit with respect to the earth. The satellites generate a plurality of beams corresponding to a respective plurality of cell. The plurality of beams has widths that vary relative to position in the orbit to maintain a cell size of the plurality of cells. A plurality of user terminals within the cells receives communication signals from the satellite. (end of abstract)
