PROBLEM TO BE SOLVED: To provide a ship steering device capable of executing constant point holding control for grasping constant point holding accuracy containing measurement accuracy of a satellite positioning system.SOLUTION: There is provided a ship steering device for a ship capable of executing constant point holding control for holding a ship body to a target position, by using a satellite positioning system, configured so that: by a reception state of a wave of the satellite positioning system, positioning accuracy level of the satellite positioning system is calculated; a constant point deviation amount level is calculated according to a constant point deviation amount calculated based on a measurement position measured by the satellite positioning system and the target position; and a constant point holding accuracy level indicating an estimated range of an absolute position of the ship body to the target position, is determined based on the positioning accuracy level and the constant point deviation amount level.SELECTED DRAWING: Figure 8

    【課題】衛星測位システムの測定精度を含んだ定点保持精度を把握することができる定点保持制御を実施可能な操船装置を提供することを課題とする。【解決手段】衛星測位システムを利用して船体を目標位置に保持する定点保持制御を実施可能な船舶の操船装置であって、前記衛星測位システムの電波の受信状態によって前記衛星測位システムの測位精度レベルが算出され、前記衛星測位システムによって測定される測定位置と前記目標位置とから算出される定点外れ量によって定点外れ量レベルが算出されるとともに、前記測位精度レベルと前記定点外れ量レベルとに基づいて、前記目標位置に対する船体の絶対位置の想定される範囲を示す定点保持精度レベルは決定される。【選択図】図8
