High accuracy positioning of two-wheeled vehicle at high speed traveling using GPS

GPS (Global Positioning System) is used in many situations but the improvement of accuracy is required. Almost all the research of GPS which have been carried out now use static receiver, only few use dynamic receiver. For two-wheeled vehicle, high accuracy positioning is difficult because of the inclination of the body which adversely affects the positioning result. We have tried to improve the result of positioning by supplementing information of unlocked satellites. Moreover, we used Kalman filter to smooth the positioning result.
