【摘要】 在MIMU(微小型惯性测量单元)角速度及加速度通道误差数学模型的基础上,提出一种利用三轴速率转台的MIMU快速高精度标定补偿方法,介绍了各参数的测量原理及误差系数的计算公式,得出了相应的误差数学模型及修正算法。利用三轴转台进行姿态运动试验,试验结果表明,补偿后系统捷联惯性导航解算的三方位姿态误差小于1.5度。该标定补偿方法对提高MIMU的工作精度具有现实意义及工程适用价值。更多还原

【Abstract】 In order to improve the anti-jamming ability and precision of MIMU,in according to error mathematical model of MIMU,a new calibration and compensation techniques were proposed.The paper introduced principle of measurement and computational formulae of any error coefficient.The error mathematical model of MIMU was achieved by MATLAB software.The experiment keeping pose of MIMU to movement was implemented by three axes truntable.The experimental results show that the errors compensated of three poses are less than 1.5 degree.更多还原
