Summary:In order to research the relationship between installation errors and the calibration accuracy of error model coefficients of gyro accelerometer which is tested on centrifuge, concerned coordinate systems are established at first, and the influences of installation errors on the input specific force of the accelerometer and the angular velocity of the accelerometer's shell are calculated by using homogeneous transformation method, and then the impacts of installation errors on the calibration accuracy of error model coefficients are analyzed in detail. The results show that if the installation errors are less than 0.001rad, they have negligible impacts on the calibration accuracy of high-order coefficients.
