Abstract
A solar cell, a charge state detection circuit and a voltage detection circuit as a generating state detection circuit that detects the generating state of the solar cell, and a control circuit are provided. The control circuit operates a GPS receiver circuit when a detection value detected by the voltage detection circuit is greater than or equal to a preset threshold value, and resets the threshold value if satellite signal reception by the GPS receiver circuit fails, or if the detection value detected by the voltage detection circuit remains less than the threshold value for a preset generating state detection time or longer.
