| 摘 要： | 探讨了组合多系统的精密单点定位(PPP),通过MGEX实测数据进行多系统PPP解算,分析了不同系统组合PPP定位精度和收敛速度,以及多系统组合对GPS模糊度首次固定时间的影响。实验结果表明,在静态和仿动态条件下,组合系统PPP的收敛速度和短时间定位精度明显优于单系统PPP,同时多系统组合PPP能够加快浮点模糊度收敛,缩短GPS PPP模糊度的首次固定时间。

| Abstract: | This article explores the combined multi-system precise point positioning (PPP).Based on MGEX data,the combined multi-system PPP is calculated and the positioning accuracy and convergence speed are analyzed.The influence of combined multisystem on the time of first-fixed solution of GPS PPP is also studied.The experimental results show that the convergence time and the short time positioning accuracy of the combined multi-system PPP are better than those of the single system PPP.The combined multi-system PPP can accelerate the convergence speed of float ambiguity,and the time of first-fixed solution can also be shorten. |
