| 摘 要： | 基于精密单点定位(PPP)原理及BDS-3 PPP-B2b电文改正模型，分析在使用电文改正信息进行PPP过程中需要注意的2个改正参数间匹配性问题，以及静态、仿动态条件下经过PPP-B2b电文信息改正后B1C+B2a、B1I+B3I模式定位服务性能。结果表明，在静态条件下，2种定位模式水平、高程方向定位精度均优于11 cm；仿动态条件下，水平、高程方向定位精度均优于22 cm，在15 min内均能达到水平、高程方向分别不超过0.3 m、0.6 m的精度要求；B1C+B2a组合在定位精度和收敛速度方面均略优于B1I+B3I。

| Abstract: | Applying the principles of PPP and Beidou-3 PPP-B2b telegram correction model, we analyze the matching problems between two correction parameters that must be attended to in using telegram correction information for PPP. We further analyze positioning service performance in two modes, B1C+B2a and B1I+B3I, after the correction of the message information under static and imitation dynamic conditions. The results show that under static conditions, the positioning accuracy in the horizontal and elevation directions of the two positioning modes are better than 11 cm. Under dynamic conditions, the positioning accuracy in the horizontal and elevation directions are both better than 22 cm; the horizontal and elevation directions can be reached within 15 min, and do not exceed the accuracy requirements of 0.3 m and 0.6 m. The B1C+B2a combination is slightly better than the B1I+B3I combination in terms of positioning accuracy and convergence speed. |
