【摘要】 为满足Multi-GNSS观测数据质量评估的需求，基于G-Nut/Anubis和MATLAB软件开发了多指标量化与可视化表达程序KMQC。该程序能够显著改善原生Anubis存在的交互性差和可视化性能低等问题，可便捷地输出BDS、GPS和GLONASS等系统的观测质量分析图表。本研究采集了KMCORS中3个基准站2022年7d的RNX3观测数据，对KMQC的性能进行测试。结果表明，该程序可高效输出CORS站的Multi-GNSS观测数据评估结果，并能够通过各型图表进行直观表达。因此，该软件能够显著降低多元GNSS观测数据的质量检核难度，可有效辅助质检部门及时监控CORS系统的运行健康度。更多还原

【Abstract】 To meet the requirements of Multi-GNSS observation quality assessment, we developed the KMQC program for its multi-metric quantification and visualization based on the G-Nut/Anubis and MATLAB software. It can significantly address the poor interactivity and low visualization performance of the original Anubis and support the outputs of the observation quality analysis for BDS, GPS and GLONASS systems. In this study, the performance of this software is tested by collecting GNSS observations from 3 sites in KMCORS for 7 days in 2022. Results show that the KMQC can efficiently output the Multi-GNSS observation evaluation results for CORS stations by using various types of graphs. Therefore, this software can significantly reduce the difficulty in Multi-GNSS observations quality evaluation and can effectively assist the quality control department to get the operational health of CORS system in time.更多还原
