WebFeb 25, 2024 · Continuous Global Navigation Satellite Systems (GNSS) data can be used for various applications. Satellite signal propagation in space depends uniquely on electron density in the ionosphere [1,2,3].Thus, the estimation of Total Electron Contents (TEC) in the ionosphere can provide valuable information to correct errors in GNSS positioning.

WebMar 24, 2024 · Finally, anew TEC retrieval technique is developed for the high-rate RO data with a top reaching at least 120 km. For better characterization of the E-to-F transition in Ne and more accurate TEC retrievals, it is recommended to have all GNSS-RO acquisition routinely up to 220 km. WebApr 12, 2024 · Ionospheric effective height (IEH), a key factor affecting ionospheric modeling accuracies by dominating mapping errors, is defined as the single-layer height. From previous studies, the fixed IEH model for a global or local area is unreasonable with respect to the dynamic ionosphere. We present a flexible IEH solution based on neural network … WebUsing GNSS to measure ionospheric TEC. Total electron content (TEC) is measured from the time delay between two frequencies.
