在局部地区GPS高程拟合中,选择不同的拟合模型和方法会对GPS高程拟合的精度产生很大的影响。本文通过对多面函数拟合模型中不同核函数中心点个数选择对GPS高程拟合精度影响的研究,通过实例计算分析得到结论:核函数中心点因个数选取的不同,对GPS高程拟合精度的影响较大,在采用多面函数模型拟合GPS高程时,应该考虑核函数中心点个数的选择问题。 更多还原
【Abstract】 GPS Height in some areas,the choice of different methods of fitting models and GPS Height accuracy will have a huge impact.Based on the multi-faceted function fitting the model number of different kernel functions chosen to center accuracy of GPS Height study,the practical calculation of conclusion,the number of the selected kernel function center is different on the accuracy of GPS Height the impact of large multi-faceted functions in the model fitting using GPS altitude should be considered th... 更多还原
