PROBLEM TO BE SOLVED: To provide a position measuring device for displaying an accurate measurement result by reducing the step display of the positioning result even when a large range where a moving body straddles an electronic reference point is measured as a measuring object, while the positioning performance is generally reduced as the distance from the electronic reference point to the moving body is increased.SOLUTION: This vehicle position arithmetic device includes a storage section for storing a predetermined hysteresis value. In this case, a reference station at the nearest distance is extracted from the distance from an independent positioning position of the moving body to a previously specified specification reference station of a plurality of reference stations and the distances obtained by adding the hysteresis value to the distances from the independent positioning position to the reference stations other than the specification reference station, this reference station is set as the specification reference station, and the travel position of the moving body is calculated based on the correction information possessed by the specification reference station and observation data from a GPS satellite. |
