WebJul 22, 2024 · Global Navigation Satellite System (GNSS)-based Earthquake (EQ) anomalies in the ionosphere and troposphere provide explicit evidences to study the coupling … WebAnomalous propagation can be a limiting factor for the propagation of radiowaves, especially the super refraction. However, reflection on the ionosphere is a common use of this phenomenon to extend the range of the signal. Other multiple reflections or refractions are more complex to predict but can be still useful. Radar

"WebAs the ionosphere is a dispersive media, the GNSS signals refraction depends on its frequencies (as the squared inverse). This dependence on the signal frequency allows us to remove its effect up to more than 99.9% using two frequency measurements (see Ionosphere-free Combination for Dual Frequency Receivers).But, single frequency … " - Two anomalies in the ionosphere
