A communication system using GPS-based time for synchronizing communication data packets and symbols. The communication system includes a transmit apparatus for transmitting and a receive apparatus for receiving a communication data signal. The transmit apparatus includes a transmit station GPS receiver for providing GPS-based time, a transmit framer for using the GPS-based time for framing packets of communication data symbols, and a transmit symbol timer for synchronizing the communication data symbols to the GPS-based time. The receive apparatus includes a GPS receiver for providing the GPS-based time, a receive framer for using the GPS-based time for receiving the packets of the communication data signal, and a receive symbol timer for synchronizing the reception of the communication data symbols to the GPS-based time. Either the transmit apparatus includes a propagation advance calculator or the receive apparatus includes a propagation delay calculator in order to compensate for the propagation delay of the communication data signal between the transmit apparatus and the receive apparatus.
