Low latitude scintillations: A comparison of modeling and observations within the CIGALA project
(2011-11-21)
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 ...

Towards forecasting and mitigating ionospheric scintillation effects on GNSS
(Ieee, 2007-01-01)
The effect of the ionosphere on the signals of Global Navigation Satellite Systems (GNSS), such as the Global Positionig System (GPS) and the proposed European Galileo, is dependent on the ionospheric electron density, ...
Extended ionospheric amplitude scintillation model for GPS receivers
(Amer Geophysical Union, 2014-05-01)
Ionospheric scintillation is a phenomenon that occurs after sunset, especially in the low-latitude region, affecting radio signals that propagate through the ionosphere. Depending on geophysical conditions, ionospheric ...
CIGALA: Challenging the solar maximum in Brazil with PolaRxS
(2011-12-01)
The upcoming solar maximum, which is expected to reach its peak around May 2013, occurs at a time when our reliance on high-precision GNSS has reached unprecedented proportions. The perturbations of the ionosphere caused ...

Tackling ionospheric scintillation threat to GNSS in Latin America
(Edp Sciences S A, 2011-01-01)
Scintillations are rapid fluctuations in the phase and amplitude of transionospheric radio signals which are caused by small-scale plasma density irregularities in the ionosphere. In the case of the Global Navigation ...
Influence of Ionospheric Scintillation on GNSS Satellite Constellation Geometry
(Ieee, 2018-01-01)
Ionospheric scintillation is a serious concern for GPS users under low latitude regions. Under extreme cases, scintillation may lead to a full disruption of the receiver operation. This work presents a statistical analysis ...
