A system using GPS data for locating a person requesting a support. The system includes a mobile terminal carried by a person to acquire the GPS data from GPS satellites and transmits the same upon a request by the person to a message center where the GPS data is processed to calculate the person(s position. The mobile terminal simply acquires the GPS data which is invalid for calculation of the position if the request is made where the GPS satellite is not available. For successfully locating the person\'s position, the mobile terminal acquires the GPS data regularly at different times in accordance with a time schedule and stores the time-series sets of the GPS data which are transmitted together with a current GPS data acquired in response to the support request, thereby giving the latest available position of the person if the current GPS data is found invalid.
