摘要:

分析不同场景PPP-B2b动态定位性能不仅对用户有重要的参考价值,也有助于BDS-3的应用推广。通过开展船载和车载动态实验,深入分析了BDS-3的PPP-B2b服务在不同场景下的动态定位性能,实验结果表明:以德国亥姆霍兹波茨坦地学研究中心(GFZ)公布的后处理产品为参考,PPP-B2b产品的轨道改正数精度可达分米级,钟差改正数精度可达亚米级。车载PPP-B2b实验中,BDS-3系统B1/B2频点的平均多路径效应(MP-RMS)为41.3 cm,全球定位系统(GPS)L1/L2频点平均MP-RMS为52.2 cm;BDS-3/BDS-3+GPS两种系统组合在水平及竖直方向的定位精度分别为10.3/5.6 cm、10.5/4.9 cm。船载PPP-B2b实验中,BDS-3 B1/B2频点平均MP-RMS为52.5 cm,GPS L1/L2频点平均MP-RMS为70.4 cm;BDS-3/BDS-3+GPS在水平及竖直方向的定位精度分别为22.5/9.7 cm、12.0/5.1 cm。海洋动态环境下多路径效应对PPP-B2b动态定位性能的影响整体略高于车载动态环境。

Abstract:

The assessment of PPP-B2b kinematic positioning performance under different scenarios will be an important reference for users and contribute to the expansion of the application scope and promotion of BDS-3. In this study, the kinematic positioning performance of the PPP-B2b service of BDS-3 under different scenarios was comprehensively analyzed by performing one vehicle experiment and one vessel experiment. Experimental results indicate that using the post-processing product released by the Helmholtz Centre Potsdam-German Research Centre for Geosciences (GFZ) as a reference, the PPP-B2b product had orbit correction accuracy up to the decimeter level and clock correction accuracy up to the sub-meter level. In the vehicle experiment of PPP-B2b, multipath-root mean square (MP-RMS) for BDS-3 B1/B2 frequencies was 41.3 cm, while that for GPS L1/L2 frequencies was 52.2 cm. The positioning accuracies of BDS-3 in the horizontal and vertical directions were 10.3 and 10.5 cm and those of the BDS-3+GPS combination were 5.6 and 4.9 cm, respectively. In the vessel experiment of PPP-B2b, the MP-RMS for BDS-3 B1/B2 frequencies was 52.5 cm, while that for GPS L1/L2 frequencies was 70.4 cm. The accuracy values of BDS-3 in the horizontal and vertical directions were 22.5 and 12.0 cm and those of the BDS-3+GPS combination were 9.7 and 5.1 cm, respectively. The overall impact of multipath effects on the kinematic positioning performance of PPP-B2b in the vessel environment was slightly greater than that in the vehicle environment.
