1. A system for time-base synchronization, comprising:

  • a first base station transceiver system (BTS) having a transmitter and receiver, the transmitter being used to transmit partial location data and a capture time at which the partial location data was received;

    a timing circuit associated with the first BTS to maintain time;

    a second BTS adapted to communicate with the first BTS to receive the partial location data and the capture time from the first BTS;

    a processor communicatively coupled to the second BTS and adapted to receive the partial location data and time therefrom; and

    a GPS receiver associated with the processor to provide complete location data to the processor, the processor being adapted to process the complete location data and partial location data to determine therefrom an accurate time at which the partial location data was received, the second BTS being adapted to provide to the first BTS time data related to the accurate time at which the partial location data was received by the first BTS, and wherein the first BTS is adapted to synchronize the timing circuit based, at least in part, on the time data received from the second BTS.
