摘要
Abstract
According to the characteristics of land vehicle navigation, the single degree of freedom accelerometer can be used as a substitute for the odometer. The Dead Reckoning(DR) scheme is proposed based on a low-cost single accelerometer with a single gyroscope. The DR system's error accumulates over time, although it has high precision in a short while. Therefore, a GPS/DR integrated navigation system is formed by utilizing the Extented Kalman Filter(EKF). It combines the advantages of both systems and improves the navigation capacity. Actual test result shows that the GPS/DR integrated navigation system can satisfy the basic requirement of land vehicle navigation. It improves the degree of precision in the city valley and is able to work even when GPS signals are masked.
