Abstract
A positioning device includes a moving amount determination section which determines a moving amount of the device in a period between a preceding positioning time and a present positioning time; a moving amount evaluation section which determines whether or not the moving amount is within a predetermined allowable moving range; a positioning section which locates a position of the device based on a satellite signal which is a signal from a positioning satellite; an average position calculation section which calculates an average position by averaging a preceding located position and a present located position when the moving amount evaluation section has determined that the moving amount is within the predetermined allowable moving range; and a position output section which outputs the average position.
