不同区域的多系统基线处理结果分析

The Comparative Analysis of Multi-system Baseline Processing in Different Regions

北斗卫星导航系统日益完善,高精度的数据处理成为研究北斗系统的前沿课题。北斗导航定位系统早已覆盖我国全部领域。本文从我国不同纬度地区提取部分观测数据进行兼容北斗系统的全球卫星导航系统基线解算,对比解算结果,验证了北斗系统系统在全国范围内的的定位精度相当,并且对比发现北斗系统基线处理的单位权方差值和均方根误差精度指标优于北斗系统/全球定位系统双系统和全球定位系统单系统的指标。

BeiDou navigation satellite system（BDS）has been improving steadily,high-precision data processing is a hot topic in BDS research.BDS has already covered the whole area of our country.The results of embedded BDS GNSS baseline processing in different latitude regions were analyzed,and it was found that the precision of BDS baseline processing is considerable in the whole country.Besides,the unit variance and the root mean square error precision of BDS baseline processing are better than BDS/GPS dual systems and GPS single system.
