| Abstract: | A car-borne integrated navigation system is introduced. In this paper, a signal-modulated circuit for the car speed sensor (Hall sensor) and rate gyro is presented. The serial port program for GPS data collecting, the format of NMEA-0183 sentences, and the GPS information extracting flow chart are given. All the data required by the integrated car-borne navigation system can be acquired. |
