A positioning control device installed in a mobile station, wherein the positioning control device determines a current location of the mobile station based on positioning requests from a plurality of applications (102, 103), comprising: a positioning unit configured to determine the current location at a positioning accuracy specified in a positioning request of an application (102, 103) and a positioning request management unit configured to return a positioning result obtained by the positioning unit in response to the positioning request from the application, wherein the positioning request management unit is configured to: when there is a new positioning request from one of the plurality of applications (102, 103), compare the positioning accuracy specified in the new positioning request with the positioning accuracy of the latest positioning result; and in a case where the positioning accuracy specified in the new positioning request is higher than the positioning accuracy of the latest positioning result, to transmit a positioning start instruction to the positioning unit to make the positioning unit determine the current location at the positioning accuracy specified in the new positioning request and return the positioning result in response to the new positioning request, or return error information in response to the new positioning request in a case where the positioning result in response to the new positioning request is an error; or, in a case where the positioning accuracy specified in the new positioning request is equal to or less than a positioning accuracy of the latest positioning result, to return the positioning result for responding to the prior positioning request in response to the new positioning request or return error information in response to the new positioning request and transmit a positioning start instruction to the positioning unit in a case where the positioning result for responding to the prior positioning request was an error. a positioning unit configured to determine the current location at a positioning accuracy specified in a positioning request of an application (102, 103) and a positioning request management unit configured to return a positioning result obtained by the positioning unit in response to the positioning request from the application, wherein the positioning request management unit is configured to: when there is a new positioning request from one of the plurality of applications (102, 103), compare the positioning accuracy specified in the new positioning request with the positioning accuracy of the latest positioning result; and when there is a new positioning request from one of the plurality of applications (102, 103), compare the positioning accuracy specified in the new positioning request with the positioning accuracy of the latest positioning result; and in a case where the positioning accuracy specified in the new positioning request is higher than the positioning accuracy of the latest positioning result, to transmit a positioning start instruction to the positioning unit to make the positioning unit determine the current location at the positioning accuracy specified in the new positioning request and return the positioning result in response to the new positioning request, or return error information in response to the new positioning request in a case where the positioning result in response to the new positioning request is an error; or, in a case where the positioning accuracy specified in the new positioning request is equal to or less than a positioning accuracy of the latest positioning result, to return the positioning result for responding to the prior positioning request in response to the new positioning request or return error information in response to the new positioning request and transmit a positioning start instruction to the positioning unit in a case where the positioning result for responding to the prior positioning request was an error.
