Anubis的GNSS数据质量检核可视化表达与分析

Visualization and analysis of GNSS data quality check on Anubis

针对目前TEQC数据质量检核软件尚不支持同时检核GPS/BDS/GLONASS/Galileo四系统观测数据质量的现状,该文基于开源代码的Anubis命令式窗口软件,重新编译Anubis软件代码,以扩展北斗导航系统新频点新信号数据的处理功能;依托Python平台实现Anubis软件的可视化界面封装以及质量检核结果的可视化输出,并对其软件功能和检核结果有效性进行验证。实验结果表明,改进后的Anubis软件能够以多种质量指标有效检核GNSS数据,满足检核新一代iGMAS接收机数据质量的需求。

In view of the situation that the TEQCsoftware for checking data does not support to deal with GPS/BDS/GLONASS/Galileo observation data at the same time,the study of data quality check was made.Based on the open source code of Anubis,the code was recompiled and the processing function of new signal data of Beidou navigation system was expanded.Then the code was packaged with an interface based on the Python platform and the checking results would visualize output of checking result.Meanwhile,the function of software and the reliability of this results was also verified.The experimental results showed that the improved Anubis software could effectively check the GNSS data with multiple quality indexes to meet the requirement of checking the data quality of the new generation iGMAS receiver.
