Deterministic retrieval of ionospheric phase screen from amplitude scintillations

, 1999
In the phase screen theory of ionospheric scintillations the ionospheric irregularities are considered as pure phase objects, and the diffraction pattern produced on the ground, by radio waves propagating through this phase screen, is obtained from ...

Low latitude scintillations: A comparison of modeling and observations within the CIGALA project

, 2011
Ionospheric scintillations can seriously jeopardize the reliability of the GNSS signals and consequently can cause significant error or outage on precise positioning applications. The threat is most acute at low latitudes where ionospheric irregularities

Discovery of Regular Daily Ionospheric Scintillation

Atmosphere
The aim of this study was to find out whether, just like in March 2015, daily regular GPS positioning disturbances caused by ionospheric scintillations occurred in other months of the solar activity cycle 24.

Investigation of low latitude scintillations in Brazil within the cigala project

, 2011
Ionospheric scintillations are fluctuations in the phase and amplitude of the signals from GNSS satellites occurring when they cross regions of electron density irregularities in the ionosphere.
