Research on Positioning Accuracy Reliability of CORS

CAI Chenghui;  
According to the tested data of CORS in a certain area, this paper analyzed and evaluated tested data, and obtained the function relationship between inner and outer precision, which could correctly rel ect the quality of observation data and CORS availability in actual measurement. Experimental results show that the CORS system inner and outer precisions are evenly distributed. The CORS system can provide centimeter-level real-time positioning service.
