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