摘要
讨论了变形监测中ＧＰＳ单历元观测数据处理方法，重点是模糊度搜索空间的构成和搜索，最优解的获得和检验以及利用相位和伪距观测量提取多路径的影响。分析了所提方法的测试结果和处理快速变形所能达到的精度。
This paper discusses the methodology to process single epoch GPS observations for deformation surveys. It takes full advantage of the characteristics of deformation surveys, i.e., the position of a surveyed point changes relatively small between two consecutive survey epochs. Special attention is given to efficient solution of carrier ambiguities and multipath effects. The tests indicate the methodology works well and an accuracy of a few millimeters is achievable. The developed method can be used to process the GPS data from both slow deformation and rapid/dynamic deformation monitoring.
