| Abstract: | A dead reckoning system (DRS) based on MCU was expatiated, which was composed of compass, rate gyroscope and odometer and its essential theory. On the above basis, a novel multilevel filtering GPS/DRS vehicles navigation and location system was designed. Positioning accuracy was further improved by using map matching. Data of positioning were communicated through GSM. Trial run experiments indicated that the system possesses higher positioning accuracy and higher reliability. |
