Abstract

Ionospheric Plasma Bubbles constitute a threat for operational systems as they create disturbances of the electron density, affecting the propagation delay, and inducing phase and intensity scintillation on the electromagnetic signals traveling through the ionosphere. In the past, some studies with data from GNSS-R instruments as TechDemoSat-1 (TDS-1), proved the detection of intensity scintillation measuring the intensity reflected over calm oceans, but it was an experimental satellite and the availability of its data is limited. In this study, an analysis of NASA CyGNSS constellation data over calm oceanic regions is presented, showing signatures of traveling Equatorial Plasma Bubbles (EPB). By studying GNSS-R data, this work has detected and characterized some of these bubbles in equatorial oceanic regions during years from 2017 to 2020, estimating their length, duration, and the increased intensity scintillation (S4).
