A selective call messaging system comprises a control point satellite uplink (24) for transmission of source information to a satellite (12), the source information having timing information, a base station (16) for receiving the source information from the satellite and for retransmitting the source information to a receiver 18. A synchronization controller 29 is coupled to the receiver 18 and remotely coupled to the control point satellite uplink. The synchronization controller comprises a decoder (40) for decoding the timing information received from the base station to provide actual timing information, an absolute time source (28) that generates a reference time, a comparator (42) for comparing the actual timing information with the reference time to provide an offset signal (44) and a transmitter for forwarding the offset signal to the control point satellite uplink to adjust timing information at the control point satellite uplink.
