摘　　要：基于武汉大学卫星导航定位技术研究中心播发的北斗实时轨道和钟差产品,采用攀达时空北斗双频手持接收机,通过实测数据分析了单北斗实时PPP的收敛时间和定位精度。测试结果表明,北斗双频手持机实时PPP收敛时间比GPS长约0.5h,但收敛后,可以达到分米级甚至厘米级的动态定位精度,与GPS实时PPP的定位精度相当。With the help of Panda dual-frequency handheld receiver,we analyze the convergence time and the positioning precise of the BDS real-time PPP by actual test data based on precise satellite orbits and clocks provided by GNSS Research Center,Wuhan University.Test results show that the convergence time of the BDS dual-frequency handheld receiver real-time PPP is about half an hour comparing longer than GPS,but its dynamic positioning accuracy can reach decimeter even centimeter level after it has converged,which is equal to GPS real-time PPP.
