摘　　要：我国自主研发的北斗全球卫星导航系统已进入全球组网的最后阶段,作为北斗卫星导航系统的重要延伸——北斗地基增强系统,是北斗应用的一个极其重要的空间基础设施。通过增加北斗卫星导航系统信号,组建多模CORS,提供多模网络RTK服务,实验证明在GPS基础上融合了BDS的双星系统较BDS/GPS/GLONASS三星系统的定位精度略有提高,并将该兼容BDS、GPS的双星CORS系统应用在地下管线的测量中,解决了困难环境的作业问题,在保证作业效率的前提下,提高数据的精度。BDS global satellite navigation system,which is independently developed in China,has entered the final stage of global networking.As an important extension of BDS satellite navigation system,BDS foundation enhancement system is an extremely important space infrastructure for BDS application.By adding the signals of BDS satellite navigation system,establishing multi-mode CORS and providing multi-mode network RTK service,the experiment shows that the positioning accuracy of the dual satellite system which integrates BDS on the basis of GPS is slightly higher than that of BDS/GPS/GLONASS,and the dual satellite CORS system which is compatible with BDS and GPS is applied to the measurement of underground pipelines,which solves the operation problems in difficult environment and ensures the operation efficiency under the premise of improving the accuracy of data.
