摘要
在GPS测量应用中,无法直接利用GPS大地高替代正常高,必须通过高程拟合进行转换。因此,如何利用GPS高程拟合求得正常高成为测绘应用领域研究的一个重要方向。本文在论述常用GPS高程拟合理论模型基础上,通过实例比较分析了几种模型的适用性及可靠性,最后得出一些有益的结论。
In the GPS measurement applications,we can＇t directly use the GPS geodetic height,it must be converted by height fitting.Therefore,how to use GPS elevation fitting seek normal height is an important direction for the application research of geomatics.This paper discusses the theoretical basis of common GPS elevation fitting model,through examples of a comparative analysis of the applicability and reliability of several models,and finally draw some useful conclusions.
