Abstract:
This research was carried out to design a hardware and a software of the GPS based on GSM network in order to evaluate the implemented system experimentally. The proposed GPS/GSM based system model includes two parts which are the mobile unit and the control station. The mobile unit consists of Personal Computer PC-A connected to GSM modem- A and GPSreceiver through the computerâ€™s USB ports, while the Control Station consists of another Personal Computer PCB connected to GSM modem-B. This setup provides communication between PC-A and PC-B via SMS protocol. The system processes, interfaces, connections, data transmission and reception of data between the mobile unit and the control station has been carried out and tested successfully and accuracies less than 9m and 0.6m are obtained compared with the original coordinates using ordinary GPS and differential GPS respectively.
