WebSupporting: 4, Mentioning: 73 - We present two examples from the cusp ionosphere over Svalbard, where poleward moving auroral forms (PMAFs) are causing significant phase scintillation in signals from navigation satellites. The data were obtained using a combination of ground‐based optical instruments and a newly installed multiconstellation navigation … WebJan 22, 2024 · Transient signal loss of the global positioning system (GPS) has been frequently observed by receivers on board the European Space Agency's Swarm mission when the satellites encounter ionospheric plasma irregularities.

WebIn this study, we developed an autodetection technique for the equatorial plasma depletions (EPDs) and their occurrence and depletion amplitudes based on in situ electron density measurements gathered by Swarm A satellite. For the first time, comparisons are made among the detected EPDs and their amplitudes with the loss of Global Positioning … WebApr 22, 2024 · There, they reveal that the annual signals inferred from the SWARM GPS-based solutions are larger than the KBR-based estimates over the Amazon River basin. ...
