摘　　要：基于新一代GPS线性轮廓滤波器的基本原理,在不失去原有特性的情况下,将封闭轮廓展开成开放轮廓来处理。在此基础上考虑到不确定度贡献因素,导出滤波后数据点的不确定度概算方法,结合封闭轮廓的评定模型,综合分析滤波对误差值评定和不确定度计算的影响,给出封闭轮廓经滤波处理后工件合格性判定准则,最后结合具体实例,得到一些有价值的结论,为深入研究GPS要素操作对测量结果的影响奠定了基础。Based on the basic principle of the GPS filtering operation,in the case of keeping original characteristic property,the closedprofile is changed to an open profile. Based on this ,considering uncertainty factors,it educes uncertainty estimating methods of filtered data. Combed assessment model of the closed profile ,it analyses the filter operation makes impact on error value and uncertainty estimate ,then the principle of judgment for filtered closed profile is put forward And at last,an example is raised,so we can obtain some important conclusions which lay the foundation for in-depth study the operation impacts on the measurement.
