近年来，随着一些机构提供的北斗实时状态空间表示（SSR）改正数据的发布，北斗实时精密单点定位（RTPPP）迎来了新的发展。然而，这些更正的质量和准确性水平仍不清楚，因为它们提供的时间并不长。本文介绍了RTPPP的数据接入方法，并对国家空间研究中心(CNES)提供的北斗实时产品质量和BDS-RTPPP的性能进行了评估和验证。据了解，目前产品存在不可用、不连续性、产品精度有限等问题。然后根据这些修正实施BDS-RTPPP以验证定位性能。 6 h观测中，北、东、上分量的静态定位最终平均结果分别达到1.31、2.15和6.18 cm，平均收敛时间为73.4 min。运动定位方面，平均收敛时间为86.1分钟，平均精度分别为4.76、6.70和7.07厘米。
In recent years, real-time precise point positioning (RTPPP) using the BeiDou Navigation Satellite System (BDS) is facing new developments thanks to the dissemination of BDS real-time state space representation (SSR) corrections provided by some institutions. However, the quality and accuracy levels of these corrections remain unclear because they have not been provided for long. In this paper, methods of data accessing for RTPPP are introduced, and the quality of BDS real-time products provided by the Centre National d’Etudes Spatiales (CNES) and the performance of BDS-RTPPP are assessed and validated. It is indicated that the products currently suffer from the issues of unavailability and discontinuity, along with limited product accuracy. BDS-RTPPP is then implemented based on these corrections to validate positioning performance. For 6-h observations, the average final result of static positioning reaches 1.31, 2.15, and 6.18 cm in the north, east, and up components, respectively, and the average convergence time is 73.4 min. As for kinematic positioning, an average accuracy of 4.76, 6.70, and 7.07 cm can be achieved after an average convergence time of 86.1 min.
