摘要
GNSS数据质量分析是GNSS基线解算的关键,随着北斗卫星导航系统的完善,RINEX2版本数据格式因其不支持北斗数据逐渐被RINEX3所取代。针对原有RINEX2版本的数据检测软件TEQC无法处理RINEX3版本数据,而其他软件难以可视化分析北斗数据的问题,以SSCORS数据为例,通过ANUBIS软件对其进行质量分析,剔除异常数据后利用GAMIT进行基线解算。试验表明,SSCORS各基准站北斗卫星数据在多路径及信噪比特征值上优于GPS卫星,整体向东南方向移动,与板块运动具有一致性,进一步说明ANUBIS可有效检测多系统异常数据,对后续CORS站数据解算具有一定的参考价值。
The quality analysis of GNSS data is the key to GNSS baseline solution.With the improvement of BeiDou navigation satellite system,RINEX2 data format is gradually replaced by RINEX3 because it does not support BeiDou data.In view of the problem that the original RINEX2 version of data detection software TEQC can’t process RINEX3 version data,while other software can’t visually analyze BeiDou data,taking SSCORS data as an example,this paper analyzes its quality through ANUBIS software,and uses GAMIT to solve the baseline after eliminating abnormal data.The experimental results show that the BeiDou satellite data of SSCORS base stations are better than GPS satellite in multi-path and signal-to-noise ratio eigenvalues,and move southeast as a whole,which is consistent with the plate movement.It further shows that ANUBIS can effectively detect multi system abnormal data,which has a certain reference value for the subsequent CORS data calculation.
