Geomagnetic Storm Impacts on Communication, Navigation, Surveillance, and Air Traffic Management (CNS/ATM)
Keywords:Geomagnetic storms, Sunspot Number (SSN), Communications, Navigation, Surveillance (CNS) and satellite solar outage
In this paper, we are studying the impacts of geomagnetic storms on Communication, Navigation, Surveillance, and Air Traffic Management (CNS/ATM) by researching and analyzing the number of hours in a geomagnetic storm per year. According to Dst (<-50 nt) in the period from 2015 to 2021 has been analyzed, associated with (Dst) less than (-50 nT), using Dst records that tabulate the amount and vigor of geomagnetic storms, Sunspot Number (SSN) it is period connects the end of the solar cycle 24 and the beginning of the cycle 25 With comparison the deterioration and interruptions of communications (Di) at Cairo international airport Geomagnetic Storm events occur when the Sun causes disruptions to aviation Communications, Navigation, and Surveillance (CNS) systems, and
elevates radiation dose levels at flight altitudes. Space weather events may occur on short time scales, with the effects occurring from seemingly instantaneous to a few days hence. The sole exceptions are the brilliant auroras, spawned by energetic electrons and ions. Energized auroras indicate the deposition of energy into the upper atmosphere, and may herald the degradation of communications,
navigation, and surveillance of aircraft in the vicinity. Therefore, decision- makers in the field of aviation should be aware that the phenomena of space weather can pose a threat to the safety and efficiency of flight operations, as the answer is to know what are the effects, the potential and consequent risks of electromagnetic storms, and the options available to mitigate those risks.
