Abstract
The survey work runs through the whole road construction. However, the current GPS technology has to erect base stations while the precision decrease with distance increasing between the rover stations and base stations. Therefore, the study and application on the CORS technology is appeared. This paper describes the composition and principle of CORS system, and analyzes the application of CORS in the road control surveying, road center lines laying-out, and vertical and transverse section. Finally it summarizes some problems of the CORS system development, and looks forward to the CORS system development.
