Ionospheric scintillation monitoring and modelling [PDF]

open access: yesAnnals of Geophysics, 2009
This paper presents a review of the ionospheric scintillation monitoring and modelling by the European groups involved in COST 296. Several of these groups have organized scintillation measurement campaigns at low and high latitudes. Some characteristic results obtained from the measured data are presented.

Mid-latitude ionospheric scintillation anomaly in the Far East [PDF]

open access: yesAnnales Geophysicae, 2003
A long-term (over 3 years) study has been undertaken to obtain a comprehensive evaluation of VHF ionospheric scintillation morphology in East Asia (at Kokobunji in Japan), using amplitude records from Transit satellites.

Multi-frequency GNSS robust carrier tracking for ionospheric scintillation mitigation

open access: yesJournal of Space Weather and Space Climate, 2017
Ionospheric scintillation is the physical phenomena affecting radio waves propagating from the space through the ionosphere to earth. The signal distortion induced by scintillation can pose a major threat to some GNSS application. Scintillation is one of

The ionospheric scintillation phenomenon

open access: yes, 2022
The SAGAIE network was deployed in West-Africa in 2013 to assess the feasibility of an equatorial for ASECNA SBAS by studying ionospheric scintillation. This study of the network’s measurements, taken between 2013 and 2016, analyzes the characteristics of the scintillation recorded by five receivers that cover Sub-Saharan West-Africa.

Climatology of GPS ionospheric scintillations over high and mid-latitude European regions [PDF]

open access: yesAnnales 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]

open access: yesSpace 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

Ionospheric Phase Scintillation Index Estimation Based on 1 Hz Geodetic GNSS Receiver Measurements by Using Continuous Wavelet Transform

open access: yesSpace Weather, 2022
The adverse effect of the ionospheric scintillation on Global Navigation Satellite System (GNSS) requires scintillation monitoring on a global scale.

A comparison of satellite scintillation measurements with HF radar backscatter characteristics [PDF]

open access: yesAnnales 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.

PECULIARITIES IN THE IONOSPHERIC SCINTILLATION SPECTRAL INDEX BEHAVIOR BY OBSERVATIONS OF THE COSMIC RADIO SOURCES AT THE DECAMETER WAVELENGTHS

open access: yesRadio Physics and Radio Astronomy, 2019
Purpose: With relation to radio astronomy, ionospheric scintillation of discrete cosmic radio sources is an undesirable effect. At the same time, ionospheric scintillations carry information on the ionospheric turbulence and are a separate object of ...

Climatology of GPS phase scintillation at northern high latitudes for the period from 2008 to 2013 [PDF]

open access: yesAnnales Geophysicae, 2015
Global positioning system scintillation and total electron content (TEC) data have been collected by ten specialized GPS Ionospheric Scintillation and TEC Monitors (GISTMs) of the Canadian High Arctic Ionospheric Network (CHAIN).
