Abstract

Earth’s ionized outer atmosphere has a significant impact on radio-frequency (RF) signals used for communication, radar, and Global Navigation Satellite Systems (GNSS) such as GPS. These effects intensify and become less predictable during elevated solar activity, particularly at higher latitudes where auroral phenomena produce complex and transient ionospheric structures that cause GNSS signal scintillations and…
