Among Unmanned Vehicle Systems, the WP-based GPS navigation system is an important factor to move from the initial departure to the desired destination. However, low-cost GPS data has many error factors so the position precision falls in case of obtaining the current position data required when a vehicle moves and the position data to move forward. This paper will propose the algorithm to improve the accuracy of GPS position data completed unstable GPS data with using three-GPS's. Finally, using the algorithm will make stable navigation system of the UV and be verified through field test.
