摘要:The changes of the Earth rotation, the plates' movement and the environment of observation can cause the point shift in the GPS network, even if the observation period is a month, the displacement of the two times cannot be ignored. In this paper, take the terrestrial network station and CORS station network in Sichuan province as an example, using the method of limit error ellipse, the horizontal direction of the station is compared and analyzed. And using the stability of the station to indicate the degree of displacement, so as to identify the stability of the fixed point and unstable fixed point; at the same time, the stability of the elevation direction of the station is analyzed by the method of mathematical statistics. It provides a theoretical basis for the analysis of the stability of the network and a reference basis for the selection of the stability of the station to do a permanent reference station.
