 note = {This paper presents a new estimation approach for the point positioning of GPS(Global positioning system) by using two filters. In order to improve the estimation accuracy, this consists of 2nd-order filter in the early stage of the estimation and then Kalman filter in the remainder stage. Effectiveness of this approach is demonstrated by the experiments by real receiver data obtained at a static point on campus of Kagoshima University.},
