To acquire highly accurate positioning result according to the situation.

In a positioning server 100, a communication part 110 receives a pseudo distance of a moving body and a pseudo distance correction value. A pseudo distance correction positioning part 120 corrects the pseudo distance by the pseudo distance correction value, and performs positioning by using the corrected pseudo distance. The communication part 110 receives the pseudo distance of a basis station and a result of independent positioning of the moving body. An independent positioning part 130 performs independent positioning relative to the basis station by using the pseudo distance of the basis station. A position correction data generation part 140 calculates a position correction value from the difference between an independent positioning result relative to the basis station and an accurate coordinate value. A position correction data smoothing processing part 150 calculates a position correction value determined by smoothing the position correction value until now. A position correction positioning part 160 performs positioning by correcting the result of independent positioning of the moving body by the position correction value. A positioning result selection part 170 selects and outputs a positioning result having higher accuracy between the positioning result by the pseudo distance correction positioning part 120 and the positioning result by the position correction positioning part 160.
