基于MEMS器件的弹载小型惯性测量设计与标定实验

针对弹载惯性测量装置小体积、低功耗的应用需求,研制了基于16488的弹载惯性测量装置,应用六位置正反转方法在三轴速率转台上对测量装置进行模型误差系数标定。实验结果表明,应用标定后的模型误差系数对原始输出数据进行补偿后,姿态测量精度得到大幅提高,能满足弹载姿态测量精度需求。

Design of Small Missile Inertial Measurement and Calibration Experiment Based on MEMS

Considering the application requirements of small-sized and low-cost missile inertial measurement unit, anovel missile inertial measurement device based on 16488 is developed. Besides, six position reversing method is appliedto calibrate the model error coefficient of the measurement equipment in three axis rate turntable. The results indicatethat attitude measurement accuracy is improved after utilizing the calibrated model error coefficient to compensate theoriginal output data which meets the demand of missile attitude measurement accuracy.
