 GPS高程曲面拟合的方法较多,我们利用移动多项式曲面拟合的基本原理,探讨了不同模型对已知点数量的多少以及已知点与拟合点之间的位置关系对精度的影响规律,通过在大连瓦房店核电厂实际工程中的实验研究,得出一些实际意义的结论,对GPS实际生产作业具有一定的指导意义。同时通过处理数据的统计与比较,给出某一地区的最优模型。 更多还原

【Abstract】 There are lots of methods about GPS height curved surface fitting.By using the fundamental principle of movement polynomial curved surface,we have probed the influence discipline about the different models on the number of the given points,and the ubiety between the given points and the fitting points on the precision.By the experimention in Dalian Nuclear Power Plant of Wafangdian,we have reached some conclusions which have directive significance to the GPS work,meanwhile,we have provided the b... 更多还原
