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 …

A unique example of a polar cap arc producing clear amplitude and phase scintillations in
GPS L‐band signals is presented using observations from an all‐sky imager and a GPS …

We examined evolution of Global Positioning System (GPS) scintillation during a substorm
in the nightside high latitude ionosphere, using 1‐s phase and amplitude scintillation indices …

Temporal and spatial changes of GPS total electron content (TEC) and phase variation,
called phase scintillation, during auroral substorms and breakups are investigated in the …

Navigation and location-based applications, including business such as transport, tourism,
and mining, in Arctic areas face a variety of specific challenges. In fact, these challenges …

We present joint analysis of fluctuations in navigation signals, positioning errors, and their
relationship to auroral disturbances occurred in March 2015. Using the precise point …

Humankind's growing reliance on advanced technologies reveals potential vulnerability to
space weather events caused by the Sun's effects on Earth. Space weather events may …
