To estimate a hull state including a steering angle with high accuracy.SOLUTION: A hull state estimation device comprises an observed value receiving part 21 and an estimation part 22. The observed value receiving part 21 receives an azimuth signal indicating a hull azimuth. The estimation part 22 inputs the azimuth signal into the state estimator to output the hull state including at least the steering angle when the hull azimuth signal is input and estimates the hull state including the hull steering angle.SELECTED DRAWING: Figure 1 【課題】舵角を含む船体状態を高精度に推定する。【解決手段】船体状態推定装置は、観測値受信部２１および推定部２２を備える。観測値受信部２１は、船体の方位を示す方位信号を受信する。推定部２２は、船体の方位信号を入力した際に少なくとも舵角を含む船体状態を出力する状態推定器に方位信号を入力し、船体の舵角を含む船体状態を推定する。【選択図】 図１
