The Establishment Of A Single Base Station CORS And Measured Precision Analysis

As there is no specific norms appropriate standards in domestic,theory of a single base station within the coverage area in a city,such as in the range of 10km, 20km, 30km, 40km and use of different regions of the known points to calculation the transformation parameters,measured within theoretical coverage.the relations the location of base station, transformation parameters and the rover to the influence of suvey. But no one can answer the questions.After establishment of a single base station, need to test of the system,in order to provide a reliable empirical data for suvery and mapping, After the introduction of the basis of the principle of continuously operating reference station building,as an example of a single base station of establishment. actual analysis of CORS of a single base station,select a different calibration points under the conditions of calculation the transformation parameters, through the measured data and comparison of the known static point data,analysis of transformation parameters of the distribution of the actual measurement and calculation the accuracy of internal and external compliance, statistical analysis of different distances from the base station can achieve precision, which gives the single base station coverage in the theory of measurement accuracy in different regions, applications for future practical engineering experience to provide reliable data, and also for the establishment of a single base station to provide reference methods and test, promoting small and medium cities CORS establishment of a single base station and later upgrade to the development of multi-CORS reference stations. And verified 10km from the base station within a single fully meet the city one, two wire control accuracy.
