Anubis与TEQC软件在多模GNSS数据质量检查中的应用与对比分析

Application and comparative analysis of Anubis and TEQC software in multimode GNSS data quality inspection

以桂林GLLG CORS基准站的观测数据为例,采用Anubis与TEQC两款软件对GPS、GLONASS、BDS和Galileo等多导航卫星系统的观测数据进行质量检查分析,通过比较,分析了观测数据的质量和Anubis与TEQC软件数据质量检查的能力。在此基础上,对Anubis的质量检查指标进行了可视化分析。结果表明:数据质量指标符合IGS经验值,两款软件检查结果相当,且具有各自的优势。但在多模数据质量检查可视化方面,相比TEQC软件,Anubis方法具有更多优点,可作为TEQC等质量检查分析软件的补充和扩展。

From the observation data of GLLG CORS base station in Guilin,the Anubis and TEQC software were used to check and analyze the quality of the observation data of GPS,GLONASS,BDS and Galileo navigation satellite systems.By comparison,the quality of the observation data and the ability of data quality checking of Anubis and TEQC softwares are analyzed.On this basis,the quality inspection indicators of Anubis are visualized and analyzed.The results show that the data quality index accords with IGS experience value,and the checks results of the two softwares are similar.Both of them have their own advantages.However,compared with TEQC software,Anubis method has more advantages in the visualization of multi-mode data quality inspection.It can be used as a supplement and extension of TEQC for other quality inspection and analysis software.
