PROBLEM TO BE SOLVED: To solve such a problem that degradation in positioning accuracy experienced in the past is repeated in some positioning environments, when positioning is performed under various environments. SOLUTION: A positioning device includes a reference positioning means 11 for pinpointing a current position by receiving a position information signal, a sensor positioning means 12 for pinpointing the current position by autonomous navigation, and a storage part 13 for storing estimated gain information 14 representing a positioning environment on the occasion of positioning in the reference positioning means 11 and the sensor positioning means 12. The reference positioning means 11 and the sensor positioning means 12 pinpoint the current position, based on the estimated gain information 14 stored in the storage part 13.
