Abstract
A position detecting apparatus includes a GPS receiver configured to catch one or more of GPS satellites and track one or more of the satellites while receiving a GPS signal or GPS signals from one or more of the satellites. A power supply controllably feeds power to the GPS receiver. A suspension time decider decides a suspension time in accordance with at least one of (1) the number of satellites caught by the GPS receiver and (2) the level of at least one of the received GPS signals, and determines whether or not the lapse of time during which the GPS receiver continues to track no satellite reaches a prescribed time. A suspension controller controls the power supply to suspend the power feed to the GPS receiver during a term equal in length to the decided suspension time in cases where the lapse of time reaches the prescribed time.
