Abstract. Aiming at the situation that there is no network and communication signal in remote areas, the idea of using satellite station difference technology to obtain relatively accurate positioning is proposed. This paper briefly introduces the current mainstream satellite station differential system, and carries out static and dynamic experiments using satellite station differential technology in the remote Ali Region of Western China. The experimental results show that the selection of satellite station differential system, the selection of receiver, the surrounding environment during observation and the motion state during observation all affect the positioning accuracy. Under the static observation conditions, the satellite station differential can obtain an accuracy better than 0.15m, and in the dynamic At low speed, the precision of 2m can be obtained. The experimental results show that the satellite station differential positioning technology is generally reliable and can be applied to many applications, such as control point measurement, position navigation and so on.
