DESCRIZIONE
The purpose is to further fulfill data which indicates a state of a movable body during turning. A movement information calculating device 10 includes a positioning sensor configured to measure a position Pw of a movable body, a velocity sensor configured to measure a velocity Vn of the movable body, an attitude sensor configured to measure an attitude AA of the movable body, a center-of-gravity information calculating module 50, and a turning information calculating module 60. The center-of-gravity information calculating module 50 calculates a center-of-gravity position PGw and a center-of-gravity velocity VGn of the movable body by using the position Pw, the velocity Vn, and the attitude AA. The turning information calculating module 60 calculates one of a turning center position TC and a pivoting position RC of the movable body by using the center-of-gravity position PGw and the center-of-gravity velocity VGn.
