2A1-J07 Development of the differential method by land mark of N characters to utilize GPS(Localization and Mapping(1))

Abstract

We thought method to reduce error of GPS data. This method is how to reset acquisition data at regular interval using the landmark constructed in the road. But this method is not able to remove mutation noise. So we made location estimation by filter with least square of fourth-order approximation. In addition, mobile robot prospect of advance in running stability by overlap a self-location of GPS and dead reckoning.
