摘要
本文总结了当前测量界对系统误差的处理方法,提出了用非线性半参数核估计来处理GPS双差定位中系统误差的方法,即用非线性半参数模型中的非参数分量表达双差模型中残余的系统误差。最后通过算例检验了此方法对于提取GPS双差定位中残余的系统误差的有效性。
This paper summarizes the methods to deal with the systematic error in surveying data and proposes a technique which uses non-linear semiparametric Kernel estimator to deal with it. It uses the non-parametric components to express the residual systematic error of daul-difference model. The effect of the technique is tested with numerical example.
