Abstract
A satellite signal reception device that can desirably receive satellite signals has a charge state detection circuit 43 and a voltage detection circuit 44 that detect if the satellite signal reception device is outdoors, and a control circuit 40. If the satellite signal reception device is determined to be outdoors based on the detection result from the charge state detection circuit 43 and voltage detection circuit 44, the control circuit 40 operates a GPS reception circuit 30. If an indoor state in which the satellite signal reception device is determined to not be outdoors continues for at least a predetermined specific time, the control circuit 40 operates the GPS reception circuit 30 at a preset scheduled reception time.
