Assessment of PPP-B2b kinematic positioning performance under vehicle and vessel scenarios
摘要
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.关键词
