Ionospheric biases correction for coordinates derived from GPS single point positioning

Gende, Mauricio; Mohíno Harris, Elsa; Brunini, Claudio Antonio; Radicella, Sandro M.; Herraiz, Miguel (2005)

Assisted code point positioning at sub-meter accuracy level with ionospheric corrections estimated in a local GNSS permanent network

Crespi, Mattia; Mazzoni, Augusto; Brunini, Claudio Antonio (2009)

Mitigation of receiver biases in ionospheric observables from PPP with ambiguity resolution

Universidade Federal do Paraná (UFPR); Universidade Estadual Paulista (Unesp); G&F/CNAM (2020-04-15)

PPP (Precise Point Positioning) is a GNSS (Global Navigation Satellite Systems) positioning method that requires SSR (State Space Representation) corrections in order to provide solutions with an accuracy of centimetric ...

Assessment of a TEC calibration procedure by single-frequency PPP

Universidade Estadual Paulista (Unesp); Universidade do Vale do Paraíba – UNIVAP (2018-04-01)

Global navigation satellite system (GNSS) measurements have become an outstanding data source for ionospheric studies using total electron content (TEC) estimation procedures. Many methods for TEC estimation had been ...

Effects of Saturn's magnetospheric dynamics on Titan's ionosphere

Edberg, N. J. T.; Andrews, D. J.; Bertucci, Cesar; Gurnett, D. A.; Holmberg, M. K. G.; Jackman, C. M.; Kurth, W. S.; Menietti, J. D.; Opgenoorth, H. J.; Shebanits, O.; Vigren, E.; Wahlund, J. E. (Wiley, 2015-10)

We use the Cassini Radio and Plasma Wave Science/Langmuir probe measurements of the electron density from the first 110 flybys of Titan to study how Saturn´s magnetosphere influences Titan´s ionosphere. The data is first ...

Calibration errors on experimental slant total electron content (TEC) determined with GPS

Ciraolo, L.; Azpilicueta, Francisco Javier; Brunini, Claudio Antonio; Meza, Amalia Margarita; Radicella, Sandro M. (2006)

Analysis of the bias between TOPEX and GPS vTEC determinations

Azpilicueta, Francisco Javier; Brunini, Claudio Antonio (2009)

Temporal and spatial variability of the bias between TOPEX- and GPS-derived total electron content

Brunini, Claudio Antonio; Meza, Amalia Margarita; Bosch, W. (Springer, 2005-06)

Total Electron Content (TEC) predictions made with the GPS-based La Plata Ionospheric Model (LPIM) and the International Reference Ionosphere (IRI95) model were compared to estimates from the dual-frequency altimeter onboard ...

Definition and implementation of a new service for precise GNSS positioning

Monico, João Francisco Galera; Morel, Laurent; Universidade Estadual Paulista (Unesp) (Universidade Estadual Paulista (Unesp), 2017-09-05)

PPP (Precise Point Positioning) is a positioning method by GNSS (Global Navigation Satellite Systems), based on SSR (State Space Representation) concept that can provide centimeter accuracy solutions. Real-time PPP (RT-PPP) ...

Magnetic aspect sensitivity of 3‐m F‐region field‐aligned plasma density irregularities over Jicamarca

Hysell, D. L.; Hedden, R. B.; Swartz, W. E.; Farley, D. T.; Chau Chong Shing, Jorge Luis; Milla, Marco (American Geophysical Union, 2011-10)

The magnetic aspect angle sensitivity of 3‐m plasma density irregularities in the F‐region ionosphere over Jicamarca has been measured during the passage of a radar plume in an equatorial spread‐F event. The measurement ...
