A signal, such as from a GNSS satellite or microwave sounding system, propagating in the
randomly inhomogeneous ionosphere, experiences chaotic modulations of its amplitude …

This paper presents a review on the PECASUS service, which provides advisories on
enhanced space weather activity for civil aviation. The advisories are tailored according to …

Abstract On 6 September 2017, an X‐class flare of the magnitude 9.3 occurred around noon
UT, being the strongest flare event in a decade. The flare itself was the highlight of a quite …

The equatorial plasma bubbles (EPBs) are depleted plasma density regions in the
ionosphere occurring during the post-sunset hours, associated with the signal fading and …

The paper aims to review recent advances regarding the observational and monitoring
capabilities of the ionization conditions in the Earth's upper atmosphere. The analysis spans …

During the intense solar radio bursts on 6 September 2017, Global Navigation Satellite
Systems (GNSS) signal interferences were observed at ground stations in the European …

Space weather can strongly affect trans-ionospheric radio signals depending on the used
frequency. In order to assess the strength of a space weather event from its origin at the sun …

It is well known that space weather can cause significant disruptions to modern
communications and navigation systems, leading to increased safety risks, economic losses …

In this paper, we evaluate the performance of the dual-frequency airborne ionospheric
gradient monitor proposed for dual-frequency multi-constellation (DFMC) Ground Based …

We use the first data set from the ground‐based TEC and scintillation receiver located at the
Norwegian Research Station Troll in Queen Maud Land, Antarctica to analyze in detail the …
