摘要
针对当前GALILEO导航系统在我国境内PPP服务的定位精度评估,采用武汉、拉萨、香港、台南四个测站的实测数据进行分析。从星座可见性、DOP值分布情况和静态PPP定位精度方面对GALILEO系统在我国境内的表现进行评估,并且将分析结果与相应的GPS及双系统组合模式结果进行对比分析。
According to the accuracy assessment of PPP service based on GALILEO navigation system on current in China,the measured data of WUH2,LHAZ,HKSL and NCKU stations was used to analyze. The performance of the GALILEO system was evaluated from the constellation visibility,the distribution of DOP values and the static PPP positioning accuracy,and the analysis results were compared with the corresponding GPS and dual system combination model results in China.
