| 摘要: |
| 在分析研究星间单差精密单点定位算法和抗差Kalman滤波解算模型基础上，利用全球定位系统、全球导航卫星系统、北斗卫星导航系统数据，对单、双、三系统精密单点定位精度和收敛时间进行了分析，得出了以下结论：三系统精密单点定位技术无论定位精度还是收敛速度均最优，多系统组合导航定位有利于提高导航定位精度。 |

| Abstract: |
| The PPP(precise point positioning) algorithm based on the single differencing between satellites and the robust Kalman filter model was studied and analyzed. And then, the global position system, global navigation satellite system and BeiDou navigation satellite system data had been used to analyze to the positioning precision and convergence time of single, double and three system PPP. Finally, the conclusion were drawn as follows: the positioning precision or the convergence speed of the three-system PPP technology is optimized, and multiple-system integrated navigation and positioning can improve the precision of navigation and positioning. |
