PROBLEM TO BE SOLVED: To improve positioning accuracy, and to reduce device cost.SOLUTION: This method includes steps for: (1) calculating a plurality of virtual positioning points by using a plurality of sets constituted respectively of a plurality of satellites for supplying positioning data; (2) calculating a first space center from the plurality of virtual positioning points; (3) calculating an off-distance from the first space center relative to each virtual positioning point; (4) calculating a responsibility amount of each satellite relative to the off-distance; (5) discriminating a satellite (hereafter referred to as a 'multipath satellite') whose responsibility amount is not below a reference value; and (6) calculating and outputting a reception position by using virtual positioning points from which a virtual positioning point related to the multipath satellite is excluded. |
