Satellite signal receiver

Abstract

A satellite signal receiver includes a satellite signal reception unit, timer, and power-on/off controlling element. The satellite signal reception unit calculates a current position of the satellite signal receiver using an electric wave from a satellite, in response to a positioning request. The timer is used to clock an elapsed time in calculating the current position of this receiver. The power-on/off controlling element controls an on/off state of power supplied to both the satellite signal reception unit and the timer on the basis of information including the positioning request, the elapsed time clocked by the timer, and a reception condition of the satellite signal reception unit. Accordingly, a period of time for supplying the power is automatically turned on/off to be shortened in cases the positioning is impossible, thus the power being saved.
