Abstract:This paper proposes a land vehicle navigation algorithm based on the global positioning system (GPS) and the dead reckoning (DR).To achieve high location and velocity accuracy, second order extended Kalman filter (SEKF) is introduced for GPS/DR integrated navigation system. And the algorithm of the first extendedKalman filter (FEKF) and the second EKF (SEKF) are given. Further, the state models and measurement models of GPS/DR are set up. For comparision purpose, the algorithm performance of FEKF and SEKF is c… Show more
