摘要

PROBLEM TO BE SOLVED: To provide a positioning device or the like capable of positioning accurately in a multipath frequent generation area with simple configuration, while limiting a load of a storage capacity to the minimum. SOLUTION: This positioning device 20 for receiving a satellite signal S1 or the like which is a signal from a positioning satellite 12a or the like has a multipath frequent generation area altitude information storage means for storing multipath frequent generation area altitude information showing the altitude of the multipath frequent generation area as altitude information of a plurality of divided domains, a location information generation means for altitude information acquisition for receiving the satellite signal S1 or the like and generating location information 156 for altitude information acquisition for acquiring the altitude information, an altitude information acquisition means for acquiring the altitude information 155c of the divided domains corresponding to the position information 156 for altitude information acquisition from the multipath frequent generation area altitude information storage means, and an altitude information using present location information generation means for generating altitude information using present location information 160 showing the present location based on the satellite signal S1 or the like and the altitude information 155c (158).
