WebApr 1, 2024 · For the storage and transfer of the TEC maps in digital form, a special standard IONEX format has been developed. Each file contains world maps of absolute vertical TEC for one day with a time resolution of 2 h. The spatial range of maps is from −180 to 180 degrees in longitude and from −87.5 to 87.5 degrees in latitude. Webnow produces a global map of total electron content (TEC) in the IONosphere map EXchange (IONEX) format [3] based on the measurements from the dual-frequency …

Measurements were made on two permanent stations “RABT”, “TETN”. WebJul 27, 2024 · 1. Introduction Over the last decades, the Global Navigation Satellite System (GNSS) has become a valuable tool for remote sensing of the ionosphere. Using dual-frequency measurements, one of the most important ionospheric quantities, the total electron content (TEC), may be obtained. pippitröja järbo
