  "textContent": "The present disclosure is to calculate an estimated position with high precision. A course estimating device includes an angular velocity calculating part a horizontal ground speed calculating part and an estimated position calculating part The angular velocity calculating part measures or calculates an angular velocity of a movable body. The horizontal ground speed calculating part calculates a horizontal ground speed based on an attitude angle, a ground course, and a ground ship speed of the movable body. The estimated position calculating part calculates an estimated position, based on a period of time from a current time point to an estimation time point, the horizontal ground speed, and an integration operation of the angular velocity.",
