To enable highly accurate measurement of the self-position of a mobile body while moving in water.SOLUTION: An underwater position correction device provided herein is configured to estimate a current position of a mobile body moving in water on the basis of a position of the mobile body while positioning and a moving direction and speed of the mobile body in water after positioning, detect a marker disposed at a predetermined position on the sea floor, and correct the estimated current position based on the detection of the marker.SELECTED DRAWING: Figure 1
【課題】移動体が水中を移動する間の自己位置を高精度に計測することを可能にする。【解決手段】測位時の移動体の位置と、測位後における移動体の水中の移動方向と移動速度とに基づいて、水中を移動する移動体の現在位置を推定し、海底において所定の位置に配置された標識を検出し、標識が検出されたことに基づいて、推定した現在位置を補正する。【選択図】 図1
