Abstract
A satellite signal reception device that can desirably receive satellite signals has a charge state detection circuitand a voltage detection circuitthat detect if the satellite signal reception device is outdoors, and a control circuit. If the satellite signal reception device is determined to be outdoors based on the detection result from the charge state detection circuitand voltage detection circuit, the control circuitoperates a GPS reception circuit. 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 circuitoperates the GPS reception circuitat a preset scheduled reception time.
