All-combination method for calibrating accelerometer

阐述了在重力场上用全组合法标定单加速度计的方法,并且推导了加速度计全组合标定法测试原理。这种方法剔出了测试设备的确定性角位置误差对加速度计误差模型系数标定精度的影响,提高了加速度计的标定精度。结合上述的理论分析,对某型号加速度计进行了实际测试和误差分析,实验结果证明本方法对于提高加速度计标定精度是非常有效的。

The paper expounded the method of calibrating single accelerometer in gravity field using all-combination method and deduced its testing principle. This method eliminates the effect of determined angular errors of test equipment while calibrating the accuracy of accelerometer＇s error model coefficients, and increases the calibrating accuracy. Combining with the theoretical analysis, the practical measurement was carried out on an accelerometer and its error analysis was conducted. Experiment results prove that this method is very effective in improving the accelerometer＇s calibrating accuracy.
