摘要： An improved GPS receiving apparatus may be worn on a user's arm and is not affected by the user's periodic arm swinging motion. A GPS signal receiver receives a GPS signal from GPS satellites, the receiver being mountable on a user's arm. A display is provided for displaying information based upon an output of the GPS signal receiver. An arm swing detecting circuit including an acceleration sensor detects the periodic swinging motion of the user's arm and outputs a corresponding periodic signal. A timing circuit sets a predetermined time during respective arm swing movements at which a GPS signal receiving operation will be performed based upon the periodic signal output by the arm swing detecting circuit. Operation timing of the GPS signal receiver is performed based on the output signal of the timing circuit so that a GPS signal receiving operation is performed at the same time during each cycle of periodic arm swinging motion to thereby cancel the effect of the periodic arm swinging motion.
