Calibration technique of gimballed inertial navigation system using the velocity error initialization

속도오차 초기화를 이용한 김블형 관성항법시스템의 교정기법

In this paper, we formulate the extended Kalman filter for calibration of gimballed inertial navigation system (GINS) at a pure navigation mode with 1500 ft/sec initial velocity and compare its performance to the linear Kalman filter's by using Monte-Carlo analysis method. It has been shown that estimation performance of the extended Kalman filter is better than that of the linear Kalman filter.
