Model identification of accelerometer is one of the most pervasive problems in calibration test of accelerometer. A method of calibrating dual orthogonal accelerometers on two-axis table is presented to eliminate the effect of the angle-setting error on calibration, thus enhancing identification precision of the accelerometer. The correlation of the model coefficients of dual orthogonal accelerometers is analyzed and the D-optimal experiment design is accomplished. Furthermore analytical solutions are deduced. The simulation experiment and measured data suggests that the standard deviation of identification of dual orthogonal accelerometers is one order of magnitude less than that of single accelerometer. Therefore, the precision of identifying the error model of accelerometer is improved.
