Abstract

Prediction means predicts a collision risk of a flying object with at least an altitude, a flying speed, and an attitude as parameters. When the prediction means determines that the collision risk is high, flight state control means controls the flying speed, the attitude, and a flying path to control the flight state of the flying object. Therefore, when the collision risk is high, it is possible to control the maneuvering of the flying object to prevent collision and to reduce impact at the time of collision.
