Positioning device, mobile terminal, positioning method, and positioning program

摘要

A device and method are provided to reduce the time required for positioning by a GPS without allowing specific parties to occupy a communication channel. An initial location acquisition unit specifies a location of a broadcasting station based on a terrestrial digital broadcasting from the broadcasting station to set the location of the broadcasting station as an initial location for positioning in a positioning unit, and the positioning unit determines a present location by receiving a radio wave from a GPS satellite.
