GPS网正常高求解方法的研究

A Study of Normal Height Solution in GPS Network

  • 摘要: 本文针对几何方法在山区存在的局限性,提出了一种考虑地形起伏影响的几何方法。试验结果表明,在山区应用该方法可以获得与平原地区精度相当的高程异常。文中推导了GPS网正常高求解的数学模型,并分析了正常高求解结果的精度。

     

    Abstract: In order to resolve the normal heights of GPS nets in mountainous areas, a new geometric method considering terrain effect is worked out in this paper. From tests in two GPS nets, We can see that using this new method in mountainous areas can get comparable accuracy as in smooth areas. A mathematic modol resolving normal heights in GPS network is given, and accuracies of normal heights resolved from this model are analysed.
