Towards the possibility to combine LOFAR and GNSS measurements to sense ionospheric irregularities
Journal of Space Weather and Space Climate, 2023 Inhomogeneities within the ionospheric plasma density affect trans-ionospheric radio signals, causing radio wave scintillation in the amplitude and phase of the signals.

Climatology of GPS phase scintillation and HF radar backscatter for the high-latitude ionosphere under solar minimum conditions [PDF]
Annales Geophysicae, 2011 Maps of GPS phase scintillation at high latitudes have been constructed after the first two years of operation of the Canadian High Arctic Ionospheric Network (CHAIN) during the 2008–2009 solar minimum.

The Ionospheric Scintillation Effects on the BeiDou Signal Receiver. [PDF]
Sensors (Basel), 2016 Irregularities in the Earth’s ionosphere can make the amplitude and phase of radio signals fluctuate rapidly, which is known as ionospheric scintillation. Severe ionospheric scintillation could affect the performance of the Global Navigation Satellite System (GNSS). Currently, the Multiple Phase Screen (MPS) technique is widely used in solving problems

Climatology of GPS ionospheric scintillations over high and mid-latitude European regions [PDF]
Annales Geophysicae, 2009 We analyze data of ionospheric scintillation in the geographic latitudinal range 44°–88° N during the period of October, November and December 2003 as a first step to develop a "scintillation climatology" over Northern Europe.

GPS and ionospheric scintillations [PDF]
Space Weather, 2007 Ionospheric scintillations are one of the earliest known effects of space weather. Caused by ionization density irregularities, scintillating signals change phase unexpectedly and vary rapidly in amplitude. GPS signals are vulnerable to ionospheric irregularities and scintillate with amplitude variations exceeding 20 dB. GPS is a weak signal system and

A comparison of satellite scintillation measurements with HF radar backscatter characteristics [PDF]
Annales Geophysicae, 2005 We examine the correspondence between high latitude ionospheric scintillation measurements made at 250MHz with the occurrence of 10MHz HF coherent radar backscatter, on 13 and 14 December 2002.
