| Abstract: | An adaptive extended Kalman filter of dead reckoning(DR) system for land vehicle navigation and its filtering algorithm are proposed in this paper. The computer simulation results show that the position.ing accuracy of the DR system can be greatly improved by replacement of simple dead reckoning algorithm with this model and adaptive algorithm in theDR system. |
