多种卫星系统下GNSS基线处理的精度分析

Precision analysis of GNSS baseline processing in various satellite systems

随着北斗卫星导航系统(BeiDou navigation satellite system,BDS)的建设进程推进,北斗卫星导航系统已在交通运输、农林渔业、水文监测、气象测报、通信系统、电力调度、公共安全等领域得到广泛应用,在GNSS的数据处理上也逐渐发挥重要的作用。通过北斗卫星导航系统与其他的卫星导航系统对于GNSS静态观测数据的基线处理进行精度分析,可以对现阶段其具体的应用和选择对策进行评估,在实际项目的成果计算中选取最合适的处理方法。

With the development of BeiDou navigation satellite system(BDS),it has been widely used in transportation,agriculture,forestry and fishery,hydrological monitoring,meteorological forecasting,communication system,power dispatching,public safety and other fields.The system also plays an important role in GNSS data processing.By the precision analysing of GNSS static surveying data through BDS and other navigation satellite systems,we can evaluate the specific application and selection countermeasures at the present stage,and select the most appropriate method in the actual projects’result processing.
