摘要： 针对高精度相关GPS数据的特点，介绍了数据处理过程中应该注意的问题，并构造了相关对称权函数来提高数据处理的质量和解算速度。首先从影响数据处理质量的主要因素分析，重点对含有粗差的相关观测数据的抗差估计模型进行研究，构造相关对称权函数对原有IGIII方案进行改进，以保证权矩阵和相应法矩阵的对称性。结果表明，改进算法不仅大大节约解算时间，同时保证模型的正确性，提高了数据处理质量。

Abstract: According to the characteristics of high precision related GPS data, the problems which should be paid attention to in the data processing are introduced, and the related symmetry weight function is constructed to improve the quality of data processing and the calculation speed.Through the analysis of the major factors which influence the quality of data processing, the robust estimation model of correlated observation data with outliers is invested and the existing IGIII scheme is improved by constructing the related symmetric weight function to keep the symmetric of the weight matrix.Then a relevant symmetric weight function is constructed to improve the original IGIII scheme, and keep the symmetric of the weight matrix and the corresponding matrix.The results show that the improved algorithm greatly saves the calculating time, ensures the correctness of the model and improves the quality of data processing.

Key words: Quality control, Related symmetric weight function, Robust estimation, Data processing, Gross error
