Several navigation and communication systems rely on electromagnetic waves that pass through the ionosphere at some moment of its working process. It’s known that the Earth’s ionosphere is a dispersive medium and highly dynamic, with seasonal characteristics that last from milliseconds to tens of years. Another important characteristic is the spatial variability of the ionosphere, which gives to this matter different approach opportunities. Among the phenomena that happen in the ionosphere, one of the most important is the ionospheric scintillation. The scintillation is an effect of the ionosphere that most affect spatial activities, specially the GNSS positioning and navigation activities. Knowing that those activities are, sometimes, esse...
