Abstract :
In order to improve the positioning precision and reliability in dead reckoning(DR)/Global Positioning System(GPS), a novel fusion method is proposed on the basis of using Bootstrap filtering in Dead reckoning and Kalman filter in DR/GPS system. The affection of the position errors accumulation is decreased, because only the velocity and acceleration parameters of DR are used when combined with the GPS observations. The feasibility of this method is proved with a simulating example of DR/GPS system.
