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
地球与行星物理论评(2024)
Abstract
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.
