ABSTRACT:
A satellite receiver includes a signal acquisition unit that is operative to receive a validation signal from a station controller located at a paging station. The satellite receiver is operative to lock onto a satellite signal. When the satellite receiver locks onto a satellite signal, the satellite receiver demodulates the satellite signal into a digital data stream that is forwarded to the station controller for packaging and retransmission as a page. The station controller includes circuitry to determine if the digital data stream is correct and intended for the station controller. If the digital data stream is correct, the station controller generates a validation signal and forwards the validation signal to the signal acquisition unit of the satellite receiver. If the digital data stream is incorrect, the station controller will forward a negative validation signal to the signal acquisition unit. In response to the negative validation signal, the signal acquisition unit will cause the satellite receiver to continue scanning the predetermined frequency range for other satellite signals.
