PROBLEM TO BE SOLVED: To enhance positioning precision even under the environment where positioning positions are dispersed. SOLUTION: This device/method is provided with a weighted regression estimation means 7 for estimating the present position, based on weighted regression estimation using the plurality of positioning positions, and a weight calculation means 6 for calculating a weight in the weighted regression estimation, based on a plurality of positioning results, in a filtering processing means 5, and calculates the present position, based on the weighted regression estimation using the plurality of positioning positions, while updating the weight in the weighted regression estimation, based on the plurality of positioning results.
