PURPOSE:To simplify the structure of the device and enable attainment of high precision by a constitution wherein a gyroscope detecting a variation of an angle in relation to the three-axial direction and an acceleration meter detecting the acceleration in the three-axial direction are fitted to a moving body in fixed relative positions. CONSTITUTION:The gyroscope 11 and the acceleration meter 12 are fitted to an airplane, without being mounted on a platform, in such a manner that the relative positions thereof in relation to the body of the plane are fixed. The output of the gyroscope 11 is given to trigonometric function converting parts 14 and 15 from a coordinate converting part 13 and thereby the posture of the airplane is operated, while the output of the acceleration meter 12 and a corrected-posture signal are inputted in an error operating part 23 and there the error indicating the difference between an actual posture and the modified posture thereof is operated. The posture error signal thus obtained is supplied to adders 16 and 17 and thus the correction of the error in relation to the operation of posture according to the output of the gyroscope is performed. |
