| 摘 要： | 惯导系统原位标定是提高恒战状态下惯导性能的重要手段.在原位标定输入输出观测数据均含有噪声的情况下,应用传统的最小二乘法进行参数辨识将会得到有偏的结果.因此,为了提高惯导误差参数的标定精度,研究了总体最小二乘法在惯导原位标定数据处理中的应用.首先给出一种16位置标定方案,推导了考虑框架轴、陀螺和加速度计安装误差的惯导系统...

| Abstract: | In-situ calibration of INS is one of the important approaches for increasing the effectiveness of inertial systems in wartime.If both of the input and output data in in-situ calibration contain have noises,the result will be a biased one when the traditional least squares method is used for parameter identification.To improve the calibration precision of INS,the application of Total Least Squares(TLS) in data processing of in-situ calibration was studied.Firstly,a 16-position calibration scheme was given,an... |
