Abstract

A positioning control device includes a GPS hardware control unit that makes GPS determine a current location at different positioning accuracies, and a positioning request management unit that makes the GPS hardware control unit carry out positioning in response to a positioning request from an application according to a positioning accuracy specified in the positioning request, acquires the positioning result, and returns the acquired positioning result to the application of the request origin. In a case where a positioning accuracy of a new positioning request is equal to or less than a positioning accuracy of a latest positioning result, the positioning request management unit reuses the latest positioning result and returns the latest positioning result in response to the new positioning request.
