| Abstract: | 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. |
