Abstract: A new data fusion method is put forward on the basis of analyzing the virtue and shortcoming of the previous data fusion methods of multiple sensors.The final results avoid the affection of the position errors accumulation because only the velocity and acceleration parameters of DR are used when combined with the GPS observations.When the GPS signal is interrupted,the final positions are predicted by using the velocity and acceleration parameters but not estimated directly from the DR system.The feasibility of this method is certified through a simulating example of GPS/DR.
