GPS/BDS基线解算的精度分析

The Position Accuracy of Baseline Solution of Global Positioning Systemand Bei Dou Satellite Navigation System

着眼于BDS基线解算的精度分析,运用双差观测值模型方法分析了基线解算的精度。在此基础上比较在GPS与BD在单系统与系统组合下卫星可见性、PDOP值,并对比在短基线与长基线下GPS与BD在单系统与系统组合下定位精度和可靠性区别,得出了系统组合下定位精度较高的结论。在研究BDS定位精度方面进行了初步尝试和有益探讨。

Focuses on BDS baseline solution accuracy analysis,analyse the use of double difference observation methods of model analysis of baseline solution precision.On the basis of comparison in GPS and BD in a single system and composite system satellite visibility,PDOP value,and in short baseline and long baseline GPS and BD in contrast to the single system and composite system positioning accuracy and reliability of the difference,it is concluded that the system positioning precision is high,the conclusion,in the BDS positioning accuracy are preliminary and useful attempt to explore.
