摘要
制作了九加速度计阵列的无陀螺捷联惯性测量组合实物模型,并进行转台实验,对加速度计输出信号做了初步分析并进行偏置误差校正和滤波处理,发现用处理后的数据进行解算所得的角速度精度明显提高了一个数量级,从而为提高无陀螺惯性测试的精度提供了一种有用的方法。
A physical model device of non-gyro inertial measurement unit (NGIMU) is made according to the nine accelerometers configuration based on the theory research by scholars at home and abroad, and the testing experiment is also made about the device at a turntable. After preliminary analyzing,bias calibration and filter processing to the data from the output of nine accelerometers by the experiment, we find the accuracy of the angular velocity computed by using the data processed raises one order of magnitude, thereby a useful method is offered to enhance the accuracy of NGIMU.
