Abstract: A mobile communication device includes a first acquisition unit, a determination unit, and a correction unit. The first acquisition unit is attached to a contestant participating in a marathon where the contestant moves along a course, acquires competition position information indicating a position of the contestant from a GNSS system, and acquires fixed position information from a fixed communication device that is arranged at a specific position in the course and stores the fixed position information indicating the specific position. The determination unit determines whether a difference between a position of the contestant that is indicated by the contestant position information and the specific position is a first threshold value or more when the contestant arrives at the specific position. When the difference is the first threshold value or more, the correction unit corrects the contestant position information, based on the specific position.

Abstract: A positioning system that uses a positioning terminal, an information provision device, and a communication network. The information provision device is configured to perform position calculations for the positioning terminal only when the results of position calculations can be considered to be successful. Thus, a load on the information provision device can be reduced.
