Abstract
An information processing device includes a global positioning system (GPS) device configured to execute position calculation processing based on data received from a satellite; a power supply controller configured to control power supply to the GPS device; and a device controller configured to monitor a state of use of the information processing device by a user, to calculate a use frequency of the information processing device per unit time, and to cause the power supply controller to intermittently supply power to the GPS device if the calculated use frequency is lower than a predefined threshold value.
