ABSTRACT:
This invention relates to a satellite signalling system. A ground station receives paging signals from an earth-bound terminal, and an up-link radio transmitter/antenna transmits paging signals and control signals to a satellite in earth orbit. An up-link receiver coupled to the satellite receives the paging and control signals. A down-link transmitter is coupled to an antenna whose beam may be directed in a predetermined sequence to a plurality of locations on earth as paging signals are transmitted to earth.
