| Abstract: | In the area of high precision geodesy research and application,the ionosphere second-order delay cannot be ignored in GPS data—processing.This paper adopts surface model which with trigonometric series to establish the ionospheric second-order delay model,analyses the ionosphere variation in half a year or a year of Xian city in recent five years,and gets some significant conclusions for research of ionospheric second-order terms. |
