Navigation method using multi-sensor for UGV(Unmanned Ground Vehicle)

A navigation method is very important on UGV. Therefore, in this research, we propose the algorithm of navigation method using Multi-GPS, Compass and IMU and it prove through vehicle test. GPS have a lot of error elements and it is impossible to receive data in an area of poor reception via a satellite. In order to make up for the weak points, the error elements decreased by using Multi-GPS and unite IMU and Compass. It can stably do dead reckoning as the result of reducing the errors and combining those sensors. In this paper, the navigation method to reduce the error is proposed by using Multi- GPS and combining together the other sensors.
