摘要
采用高程拟合的方法求解GPS点的正常高,以苏州市GPS网为例,介绍了GPS水准拟合的原理与方法,并着重分析了不同数量的拟合点,不同分布的正常高拟合结果,将拟合结果与三、四等水准测量成果进行了比较,得出该方法可以达到国家三等水准测量的精度。
This paper adopts the method of height fitting to solve the normal height of GPS points. Based on the example of Suzhou GPS network, the authors introduce the principle and method of GPS leveling fitting, then analyze the fitting points of different number and the fitting result of normal height with different distribution and compare the result with third and fourth classes leveling achievements. It is concluded that the method can reach the level Grade-3 precision requirement.
