子午工程二期GNSS电离层TEC与闪烁监测仪样机测试及数据对比分析

Domestic global navigation satellite system ionospheric total electron content and scintillation monitor prototype testing and data quality comparison analysis for the Phase II of Chinese Meridian Project

子午工程二期电离层TEC与闪烁接收机布网采用国产设备.经过连续3天的运行测试,本文以同台站同天线的国外对比设备PolaRx5数据为参考,对样机的数据进行质量评估.对于科学研究,数据的连续性和有效性,VTEC、幅度闪烁指数、相位闪烁指数这三项数据的精度是最重要的指标.本文根据科研场景设计了这些方面的数据比较标准,评估样机的数据质量,并对两种设备探测结果特征的原因进行了分析,为数据准确性的评估提供参考和借鉴.

The global navigation satellite system(GNSS)ionospheric total electron content(TEC)and scintillation monitors in the Phase II of Chinese Meridian Project network provide domestic measurements.After 3 consecutive days of testing,we used PolaRx5 data with the same antenna as a reference to evaluate the quality of the prototype data.For scientific research,the continuity and effectiveness of data,as well as the accuracy of vertical TEC,amplitude scintillation index,and phase scintillation index values,are the most important indicators.In this study,we designed data comparison standards for these aspects based on scientific research scenarios,evaluated the data quality of the prototype,and analyzed the reasons for the characteristics of the detection results of the two devices.These findings provide a reference for the evaluation of data accuracy.
