Abstract
An azimuth measuring device is provided that can obtain offset information when the direction of the azimuth measuring device is arbitrarily changed. The offset information is calculated based on coordinates of a reference point obtained by a reference point estimating system. The azimuth measuring device can obtain the offset information without obtaining erroneous offset information when changing direction.
