碩士 === 國立成功大學 === 機械工程學系碩博士班 === 96 === In navigation applications like real-time vehicle navigation, systems assembled by inertial measurement units usually have integral error from sensor’s internal noise and external disturbance error when running system. Because these error sources increases measurement error of navigation information, we present a simple design of inertial navigation system’s structure for suppressing the external disturbance error. From the results of experiments, the performance of suppressing disturbance error can improve accuracy of navigation system. And then, we integrated the structure and compensation error systems to advance the effects of suppressing internal error and external error. Finally, the integrated system design can acquire better accuracy in navigation applications.
