不同区域的BDS实时用户保护水平研究分析

Research and Analysis on BDS Real_time XPL in Different Areas

随着GNSS的不断增加,GNSS完备性监测逐渐成为研究的热点领域。针对GNSS的完备性监测,本文提出了实时用户保护水平。为了分析BDS下不同区域的实时用户保护水平的差异,本文利用水平保护水平和垂直保护水平模型;结合四个区域的监测站的实时监测结果;对BDS的实时用户保护水平结果进行了计算分析,并验证了该算法的稳定性。

With the continuous increase of GNSS. Completeness monitoring is a hotspot of GNSS research field. For a com- pleteness monitoring of GNSS, this paper presents the real-time horizontal/vertical protection level. In order to analyze the difference of real time horizontal/vertical protection level of the BDS in different regions. In this paper, using the horizontal protection level and vertical protection level model, using real-time monitoring results of CORS stations in four regions, calculated and analyzed real-time horizontal/vertical protection level results of BDS satellite system, and verify the stability of the algorithm.
