摘要
随着北斗地基增强系统在全国范围内的建设和推广,极大地提高了北斗卫星导航系统的定位精度。沿海北斗地基增强系统是北斗卫星导航系统的重要组成部分,为我国沿海提供北斗高精度米级差分导航与北斗厘米级实时动态精密定位服务。本文通过沿海北斗地基增强系统在港口航道测量中的实际应用测试,分析系统在海上测量应用中的使用效果、精度情况、测量过程中出现的问题与现象等,为完善和深入推广沿海北斗地基增强系统的海上应用提供参考。
The construction and wide application of the continuously operating reference stations(referred to as"CORS")nationwide has greatly improved the positioning accuracy of the Beidou navigation satellite system(referred to as"BDS").The maritime BDS CORS,which is an important part of the BDS,can provide meter-level high-precision differential navigation and centimeter-level real-time dynamic precise positioning services in China's coastal areas.Based on the practical application of BDS CORS in the hydrographic survey in port and waterway,this study analyzes the effect,accuracy,problems of the BDS CORS in the hydrographic survey,so as to provide the basis for the improvement and wider application of the BDS.
