| 摘 要： | 本文利用经典平差方法对鑫诺卫星的观测数据进行处理,采用偏度、峰度正态假设检验其残差值是否服从偶然分布,进而判断参数估计结果可靠与否。检验结果表明,残差时间序列的频率直方图不服从正态分布,最小二乘平差方法在处理此观测数据所得到的估计结果是不可靠的。鑫诺卫星观测数据不仅含有偶然误差,还存在系统误差等。本文采用数字滤波方法模型化系统误差及迭代平差的方法,达到提高数据处理精度的目的。

| Abstract: | The paper processed the data of Xinnuo Satellite by using the classical squares adjustment methods,and the inspection methods of skewness and kurtosis to judge whether the residual value are normally distributed in order to judge whether the results are reliable.The frequency histogram of residual error is non-normally distributed through the inspection.In this case,the observation data of Xinnuo Satellite contained not only accidental errors,but also systematic errors.The paper put forward the methods of d... |
