| 摘 要： | 主要介绍了几种GPS高程拟合方法的理论模型及各自的优缺点，并在此基础上通过一些实例来比较分析这几种模型的适用性及精度的可靠性，指出拟合阶次的增大对公共联测点的拟合精度有很好的改善，但并非随着多项式阶数的增加外符合精度也在提高。

| Abstract: | It introduces the theoretical model of several GPS elevation fitting method and their own advantages and disadvantages,and makes a comparative analysis of the applicability and the reliability of the preciseness of these models through some examples,and points out that the increasing of fitting order can greatly improve the fitting preciseness of common conversion survey point,but the exterior fitting preciseness is not surely to increase with the increasing of polynomial order. |
