北京市基准站北斗三号卫星数据质量评估
Data quality evaluation of BDS-3 satellite at Beijing benchmark station
摘要
Abstract
In order to analyze the data quality differences of Beidou navigation satellite system-3(BDS-3)frequency points within the scope of Beijing,a self-developed global navigation satellite system(GNSS)data quality analysis software was used to conduct statistical analysis on the observation stations from the aspects of cycle slip ratio,signal-to-noise ratio,data integrity rate,multipath effect,and other indicators,and the quality of BDS frequency point observation data from multiple observation stations in the Beijing continuous operational reference system(CORS)was evaluated.The experimental results show that the BDS-3 frequency points have good consistency,and the data integrity rate at each frequency point is roughly the same.The signal-to-noise ratio of the newly added B2a signal is significantly higher than that of the B1C signal.The data integrity rate,multipath effect,and other indicators of inclined geosynchronous orbit(IGSO)satellites in Beijing are better than those of medium Earth orbit(MEO)satellites.关键词
