Abstract： In order to detect the positioning effect of Beidou single base station CORS system and the positioning accuracy of RTK measurement in Kailuan Qianjiaying mining area, this paper introduces the characteristics of single base station CORS system and upgraded compatible ' Beidou ' system in Kailuan Qianjiaying mining area. The RTK measurement data of BDS + GPS and GPS are analyzed to detect the satellite positioning effect, and the static known point detection method is used to detect and analyze the satellite positioning accuracy. The research shows that when the satellite signal is occluded, the RTK measurement fixed solution rate of receiving BDS + GPS signal is higher and the plane error is smaller. In the range of 50 km from the CORS base station, the RTK positioning accuracy reaches centimeter level. The horizontal accuracy in BDS + GPS mode is less than 2 cm, and the vertical accuracy is less than 3 cm, which is better than the measurement accuracy in GPS mode.
