L-band scintillations and calibrated total electron content gradients over Brazil during the last solar maximum
(Edp Sciences S A, 2015-12-08)
This work presents a contribution to the understanding of the ionospheric triggering of L-band scintillation in the region over Sao Paulo state in Brazil, under high solar activity. In particular, a climatological analysis ...
Middle‐ and low‐latitude ionosphere response to 2015 St. Patrick's Day geomagnetic storm
(American Geophysical Union, 2016-03-10)
This paper presents a study of the St Patrick's Day storm of 2015, with its ionospheric response at middle and low latitudes. The effects of the storm in each longitudinal sector (Asian, African, American, and Pacific) are ...
Effects of the 12 May 2021 Geomagnetic Storm on Georeferencing
(MDPI, 2022)
In this work, we present the positioning error analysis of the 12 May 2021 moderate geomagnetic storm. The storm happened during spring in the northern hemisphere (fall in the south). We selected 868 GNSS stations around ...
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, ...
Improvement of retrieved FORMOSAT‐3/COSMIC electron densities validated by ionospheric sounder measurements at Jicamarca
(American Geophysical Union, 2011-09-01)
Inversion techniques applied to GPS‐LEO radio occultation data allow the retrieval of accurate and worldwide‐distributed refractivity profiles, which, in the case of the ionosphere, can be converted into electron densities ...
