A course estimating device 10 includes an angular velocity calculating part 30, a horizontal ground speed calculating part 70 and an estimated position calculating part 80. The angular velocity calculating part 30 measures or calculates an angular velocity of a movable body. The horizontal ground speed calculating part 70 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 80 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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Course estimating device, method of estimating course, and course estimating program","description":"The present disclosure is to calculate an estimated position with high precision.
