To provide an azimuth error function acquiring device with which it is possible to acquire an azimuth error function that indicates an error of an observed azimuth relative to a true azimuth using the azimuth of an object as a variable.SOLUTION: In an azimuth error function acquiring device (20), an azimuth error amount update unit (30) estimates a movement state amount that indicates the movement state of an object and the current time state of an azimuth error amount that indicates an error of an observed azimuth error relative to a true azimuth on the basis of the observed value derived by observing the movement state of the object, and updates the estimated value of current time state of the movement state amount and azimuth error amount. An azimuth error function estimation unit (32) updates the estimated value of an azimuth error function that indicates an error of observed azimuth relative to a true azimuth using the azimuth of an object as a variable on the basis of the estimated value of current time state of the azimuth error amount updated by the azimuth error amount update unit (30).SELECTED DRAWING: Figure 1

    【課題】 対象物の方位を変数とし真の方位に対する観測される方位の誤差を示す方位誤差関数を取得することが可能な方位誤差関数取得装置を提供する。【解決手段】 方位誤差関数取得装置(20)では、方位誤差量更新部(30)は、対象物の移動状態を観測した観測値に基づいて、対象物の移動状態を示す移動状態量及び真の方位に対する観測される方位の誤差を示す方位誤差量の現時刻状態を推定し、移動状態量及び方位誤差量の現時刻状態推定値を更新していく。方位誤差関数推定部(32)は、方位誤差量更新部(30)によって更新された方位誤差量の現時刻状態推定値に基づいて、対象物の方位を変数とし真の方位に対する観測される方位の誤差を示す方位誤差関数の推定値を更新していく。【選択図】 図1
