PROBLEM TO BE SOLVED: To provide a location information monitoring system that, when acquiring location information about a moving body, determines whether the location information is correct or not and precludes a determination of a movement of the moving body if the location information is incorrect. SOLUTION: The location information monitoring system, which monitors location information about a moving body to determine a movement of the moving body according to a change in the location information, compares the latest location information and past location information out of location information acquired by a location detection part, to determine whether the latest location information is correct or not according to the distance between points indicated by the location information. A movement of the moving body is determined in dependence on such location information as the determination finds correct. COPYRIGHT: (C)2005,JPO&NCIPI |
