Comunicació de congrés
Accés restringit per política de l'editorialThe Monitor project has been designed to monitor ionospheric events that would allow evaluating its impact on European GNSS Systems. It includes a network of ionospheric scintillation monitoring stations in various ... -
Characterization and modelling of the ionosphere for EGNOS development and qualification
Schlüter, S.; Prieto Cerdeira, Roberto; Orús Pérez, Raul; Lam, J.P.; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; Hernández Pajares, Manuel (2013)
Comunicació de congrés
Accés restringit per política de l'editorialThe availability of representative data samples, models and statistical information derived from the analysis of parameters that adequately describe the state of the ionosphere are key elements for the design, verification ... -
Definition of an SBAS ionospheric activity indicator and its assessment over Europe and Africa During the last solar cycle
Sanz Subirana, Jaume; Juan Zornoza, José Miguel; Hernández Pajares, Manuel; Prieto Cerdeira, Roberto; Schlueter, Stefan (2013)
Comunicació de congrés
Accés restringit per política de l'editorialIn this work, an ionospheric activity indicator is defined based in the “weighted” Along Arc TEC rate (AATR). It is shown that this indicator, which can be easily computed from the GPS carrier phases, is well correlated ... -
Distribution and mitigation of higher-order ionospheric effects on precise GNSS processing
Hernández Pajares, Manuel; Aragón Ángel, María Ángeles; Defraigne, Pascale; Bergeot, Nicolas; Prieto Cerdeira, Roberto; García Rigo, Alberto (2014-04)
Article
Accés obertHigher-order ionospheric effects (I2+) are one of the main limiting factors in very precise Global Navigation Satellite Systems (GNSS) processing, for applications where millimeter accuracy is demanded. This paper summarizes ... -
