Creating the virtual original observations of high accuracy GPS data based on CORS

CHEN Zhong-xin,ZHU Li-qiang(Suzhou Industrial Park Survey Department,Jiangsu Suzhou 215021,China)  
At present,the built CORS system only provides the real-time differential service.Because of the long-distance between station and base station and needing enough observation time,the application of CORS is limited in the post process with mm level.This research used least-squares interpolation methods to obtain the space-related error of any point within the network,by using accurately known coordinates,as well as the baseline between actual observational data and the base stations in CORS,resolved the simulation GPS observation data by the virtual base station,realized a short baseline between the CORS station and the virtual base station,which could obtain high-precision results in a short time.It also has been tested the accuracy of calculation and analysis in Suzhou CORS,received the conclusion about time and positioning accuracy in this mode.This research has the practical value and significance of the promotion for the applied research on the high-precision fast positioning under different requirements of CORS.
