基于武汉大学自主研制的卫星导航系统综合处理软件(PANDA),利用全球实测的GPS/GLONASS、GPS/Gali-leo试验卫星(GIOVE)多模接收机数据进行GPS、GLONASS、GIOVE卫星的融合精密定轨理论与方法研究。通过与IGS提供的GPS与GLONASS卫星精密轨道比较、轨道重叠弧段互差以及SLR观测数据检核等多种方法对融合计算的精密轨道精度进行了评定。 更多还原

【Abstract】 Based on the self-developed software PANDA,this paper carries out investigations on integrated precise orbit and clock offset determination of multi-GNSS.Then precise orbit and clock offset determination of GPS,GLONASS and GIOVE have been implemented through actual global multi-mode receiver data,including GPS/GLONASS,GPS/Galileo experimental satellites(GIOVE).By comparison with IGS provided precise orbits for GPS and GLONASS,together with differences of orbit overlap arc,and SLR observable vali... 更多还原
