Abstract:

In order to identify the error model coefficients proportional to higher-order acceleration in error model identification of inertial navigation platform, an identification scheme based on centrifuge testing is developed. By analyzing the force on inertial navigation platform under the overload situation, the installing of inertial navigation platform on the centrifuge and the identification scheme are given. According to the scheme, an dentification experiment using extended Kalman filtering is followed. The results show that this method is valid for the identification of the error model coefficients which are proportional to higher-order acceleration, furthermore, it has a high identification accuracy.
