Use of spread spectrum for providing satellite television or other data services to moving vehicles equipped with small size antenna

摘要

Method, system and apparatus for providing dedicated service, using transponders arranged on the geostationary orbit, including satellite television and other data to moving vehicles, equipped with small (less then 30 cm in diameter), low profile antennas, and using signal spreading technique in order to increase the downlink signal strength and to reduce the interference from adjacent satellites ensuring in that way enough margin for the reception by the small size low-profile antennas.
