CORS定位精度的可靠性研究

Research on Positioning Accuracy Reliability of CORS

对某地区连续运行参考站系统(CORS)的实测数据进行分析评价,得到内外符合精度之间的函数关系,正确反映了观测数据的质量及CORS在实际测量中的可用性。实验结果表明,该地区的CORS系统网内外精度分布均匀,可以提供cm级的实时定位服务。

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.
