Since the position detection system using GPS receives a radio wave from a satellite and detects the position, it cannot be used for indoor users who do not reach the radio wave. In addition, since the accuracy of position detection has a certain limit, the accuracy is not sufficient for performing guidance or the like in an area where facilities are dense, such as an exhibition hall. On the other hand, in the case of the position detection system using the PHS, since the detection method determines which relay area the PHS terminal is located in, the accuracy of the position detection is high when the area covered by the base station is large. Lower. The position detection system using the PHS generally has an accuracy of about several hundred meters, and is effective for grasping a rough position outdoors. However, it requires an accurate position detection indoors. In such a case, accurate position detection cannot be performed.
