Analysis and Research of Single Base Station CORS Precision

Abstract:

Around the single station CORS system, a series of relevant experiments were conducted, the measurement was analyzed. Through base station as the center, different distances of single base station GPS-RTK measurement were carried on , the radius of actual operation and its changing law with the base station distance were obtained concluded , the measurement precision was Obtained by measuring static GPS control points,; the measurement actual coverage area positioning accuracy was confirmed, Internal, extern al accord accuracy was calculated and analyzed., the system actual service radius and The extent of different range accuracy was obtained . the results show that the single base station system is more suitable for the development of small and medium-sized cities, its actual operating radius is 28km, it can completely satisfy the city one or two traverse survey in 18 km.
