摘要
首先对GPS高程拟合的几种数学方法进行讨论和分析,给出了相应的数据模型。并针对长江三峡库区航道测量的特殊性和困难性,利用该地区的一些GPS测量数据,进行计算、分析,为该地区下一阶段GPS高程测量筛选出优化方法,得出一些有益的结论。
Based on the analysis of several mathematical methods for GPS elevation fitting,this paper provides corresponding mathematical models.In light of the special and difficult condition of waterway survey in Three Gorges Reservoir Region and utilizing some GPS survey data of the region,this paper carried out calculation and analysis,selected an optimized method for the next-stage GPS elevation survey,and drew some valuable conclusions.
