Abstract
A semiconductor device includes an atmospheric pressure value obtaining unit configured to obtain an atmospheric pressure value from an atmospheric pressure sensor; and a control unit configured to detect a variance state of the atmospheric pressure value obtained with the atmospheric pressure value obtaining unit. The control unit is further configured to control an on state and an off state of a power source of a GPS (Global Positioning System) device according to a determination whether the variance state satisfies a specific condition. The GPS device is configured to detect a position thereof based on a GPS signal received therewith and output positional information.
