PROBLEM TO BE SOLVED: To speedily align an inertial device provided on a flying object. SOLUTION: The flying object is provided with a roll angle estimation means for finding the roll angle of the flying object on the basis of output information from a plurality of infrared sensors provided on the periphery of the trunk of the flying object; an attitude angle initial estimation means having a GPS gyro for calculating coordinates of the position, the pitch angle, and the yaw angle of the flying object; a steering gear control means for performing control so that the GPS gyro becomes in an attitude capable of receiving a GPS signal from a GPS satellite; and a navigation device for aligning the inertial device on the basis of the inertial information input from the inertial device mounted on the flying object, and the position coordinates, roll angle, pitch angle, and yaw angle of the flying object input from the attitude angle initial estimation means, and calculating the position and attitude angle of the flying object.
