摘要 大范围GPS水准拟合模型 ,必然存在模型误差 ,考虑模型误差 ,如何选取GPS水准的拟合模型是本文讨论的主题。文中通过一个大测区GPS水准实测数据 ,说明拟合模型优选准则的应用以及具体分析方法。 Model errors are inevitably existed in a large-scale GPS leveling fitting model.This paper mainly deals with such model errors and on how to choose the fitting function model of GPS level.Through using actual GPS leveling fitting data in a large-scale area,it introduces the application of optimum function model choice and the related analysis method.
