Application of ionospheric corrections in the equatorial region for L1 GPS users
(2000-01-01)
In the absence of the selective availability, which was turned off on May 1, 2000, the ionosphere can be the largest source of error in GPS positioning and navigation. Its effects on GPS observable cause a code delays and ...
Equatorial and low latitude ionosphere during intense geomagnetic storms
(Elsevier, 2006-12)
An investigation is made in order to analyze the role of neutral gas composition in the equatorial and low latitude ionosphere during intense geomagnetic storms. To this end data taken by the Dynamic Explorer 2 satellite ...
Ionospheric storm effects at the equatorial anomaly
(American Geophysical Union, 2004-12)
Ionospheric disturbances produced at the equatorial anomaly (EA) region during some geomagnetic storms were investigated using hourly NmF2 peak electron density of F2-layer values from stations located at equatorial and ...
On the local time dependence of the penetration of solar wind-induced electric fields to the magnetic equator
(European Geosciences Union, 2009-08-05)
For a period of a few hours, the penetration of electric fields of solar wind origin is at its highest efficiency. In November 2003, five days of continuous vertical drift data were obtained at the Jicamarca Radio Observatory. ...
Avaliação de funções para modelagem do efeito da refratação ionosférica na propagação dos sinais GPS
(Universidade Estadual Paulista (Unesp), 2003)
Atualmente, a maior fonte de erro sistemático no posicionamento com receptores GPS de uma freqüência é devido à refração ionosférica. O erro associado à refração ionosférica depende do conteúdo total de elétrons (TEC) na ...

Interplanetary drivers of ionospheric prompt penetration electric fields
(Elsevier, 2010-02-10)
In this paper we discussed the penetration effects of common interplanetary magnetic cloud (MC) structures like sheath region, both sheath and magnetic cloud boundary layer (MCBL), MC body, and shock-running into a preceding ...
GNSS ambiguity resolution with ratio and fixed failure ratio tests for long baseline network RTK under ionospheric activity
(2020-06-01)
To perform network RTK positioning, a user must receive and apply the information generated from a network. Corrections are generated for the user to consider the atmospheric delays (ionosphere and troposphere) between ...
