摘    要:GPS平面精度之高已被人们共识和接受,但其高程精度如何,一直是人们普遍关心的问题。本文综合利用GPS测量成果和水准测量资料,采用两种方法拟合高程异常在区域中的分布,用剩余已测点的数据对其进行检验,计算及比较各种方法的拟合精度。通过对实测数据的计算分析和发现,GPS高程用于确定正常高是有使用价值的。

关 键 词:GPS/水准  多项式拟合  多面函数拟合

Abstract:The high accuracy of GPS-plane has been reached and accepted,but the accuracy of how the elevation has been a problem of general interest.In this paper,the results of comprehensive utilization of GPS measurements and leveling data,using two methods fitting height anomaly distribution in the region,with the remaining data points have been measured for their inspection,calculation and comparison of different methods of fitting precision.By the calculation of the measured data analysis and found that,GPS is us...
Keywords:GPS /Standards  Polynomial Fitting  Multi-faceted Function Fitting
