  In the calculation of high-precision GNSS data,solid tides,tides and atmospheric tides are not negligible factors in the solution process.In the present study,a large number of studies have been conducted on the effects of tidal load.The results show that the tide load The impact can reach the magnitude of cm.Relatively speaking,ATML is weak and there are few studies,but it is still a non-negligible interference factor,especially for the data calculation of national stations For example In this paper,GAMIT/GLOBK is used to solve the data of national stations in some provincial areas in 2017.
