摘要
针对现有各种 GPS水准存在的缺陷 ,我们运用现代计算数学的最新研究成果 ,提出了一种新的 GPS水准 B样条最小二乘拟合法。通过对我国西南某地区的 GPS测量成果进行处理的具体结果可以看出 ,该方法是一种更适用于高精度
Based on the latest research in computational mathematics, the principle and computing method of B-spline least squares are presented as a new method in response to overcome the defects which are often occur in the contemporary GPS leveling. The surveying data with GPS in southwest of China are disposed by using B-spline least squares, through the numerical results we can draw a conclusion that the precision and stability of B-spline least squares are better than other calculation methods in local GPS leveling.
