Trends in Satellite Communications

Abstract

Recent years have witnessed dramatic changes in telecommunications. These are nowhere more apparent than in the communications satellite sector. The sudden change from a regulated monopoly to a competitive structure in American telephone service has set a new direction for the US and possibly for international services. Regional satellite systems have appeared to complicate the role of Intelsat. National satellite systems have continued to grow and have moved into the 11/14 GHz band of frequencies. Direct broadcast of television signals to the home by satellite has emerged, become confused, and is changing in response to new technology. The space shuttle and Ariane rocket launchers have provided important new routes to space, although the current status of the space shuttle remains in question. New spacecraft/launcher ideas have emerged for powerful new systems. Policy and technical innovation will continue and may significantly change the character of satellite communications systems before the end of this decade.
