摘　　要：针对TEQC不支持RINEX3.0x格式及BNC操作不便的缺点,引入能对多系统数据进行质量检查的软件Anubis:首先对Anubis的使用方法和可视化操作进行介绍,并以IGS参考站长春站、武汉站单天的观测数据为例,分别利用TEQC和Anubis进行处理分析;然后对jfng站多系统数据的单点定位精度、多路径误差及信噪比作可视化分析;最后为进一步分析恶劣环境下Anubis处理多路径的效果,对实测数据进行处理。实验结果表明Anubis处理结果详实全面,绘图结果直观明了,可对GNSS数据质量进行有效的检查。Aiming at the problems that TEQC does not support the format for RINEX3.0x, and BNC is inconvenient to operate, the paper introduced the software Anubis which can check the quality of multi system data： the usage and visualiza tion operation of Anubis were given, and the comparative analysis on the application of TEQC and Anubis was carried out by taking the single day measures of the IGS reference stations Changchun and Wuhan as the example; then the single point posi tioning precision, multipath errors and SNR of multi system data of jfng station were analyzed visually; finally, in order to further analyze the processing effect of multipath with Anubis under severe observation environments, the measured data were used. Experimental result showed that Anubis could process data comprehensively, draw the results intuitively and clearly, so that it could be used to check the quality of GNSS data effectively.
