Blazquéz, E.B. ; Gil, A. J. ; Rodríguez Caderot, Gracia ; Lacy de, María Clara ; Ruíz, J. J. | Springer | 2003-08In the 1991 the first determination of a gravimetric geoid in a test area in central Spain was computed by using least square collocation. In 1995 a gravimetric geoid in the Iberian Peninsula, Ibergeo95, was calculated by FFT. Nowadays an improv[...]texto impreso
Rodríguez Caderot, Gracia ; Lacy de, María Clara ; Gil, Antonio José ; Blázquez, B. | Springer | 2006-10This work focuses on the comparison between satellite-only and combined Global Geopotential Models (GGMs) derived from the CHAMP and GRACE satellite missions with land gravity anomalies, geoid undulations provided by the gravimetric geoid ANDALU[...]texto impreso
Gil, A.J. ; Rodríguez Caderot, Gracia ; Lacy de, María Clara ; Ruiz, A.M. ; Sanz De Galdeano-Equiza, Carlos ; Alfaro, Pedro | Springer | 2002The Granada Basin (Central Betic Cordillera), one of the most seismically active areas of the Iberian Peninsula, is currently subjected to NW-SE compression and NE-SW extension. The present day extension is accommodated by normal faults with var[...]texto impreso
Alfaro, Pedro ; Estévez Rubio, Antonio ; Blázque, E. B. ; Borque Arancón, María Jesús ; Garrido, M. S. ; Gil, Alejandro J. ; Lacy de, María Clara ; Ruíz, A. M. ; Giménez, J. ; Molina Palacios, S. ; Rodríguez Caderot, Gracia ; Ruíz Morales, M. ; Sanz De Galdeano-Equiza, Carlos | Springer-Verlag Berlin Heidelberg | 2006The Betic Cordillera, located in the south of the Iberian Peninsula, is currently subjected to NW-SE compression and NE-SW extension. Until a few years ago, there were hardly any geodetic studies to quantify the tectonic deformation taking place[...]texto impreso
Ruíz, A. M. ; Ferhat, G. ; Alfaro, Pedro ; Sanz De Galdeano-Equiza, Carlos ; Lacy de, María Clara ; Rodríguez Caderot, Gracia ; Gil, Antonio José | Elsevier Science B.V | 2003-04The Granada basin, located in the central sector of the Betic Cordillera, is one of the most seismically active zones of the Iberian Peninsula. For the first time, a geodetic network along the Padul fault and two levelling profiles (Genil and Vi[...]texto impreso
Lacy de, María Clara ; Rodríguez Caderot, Gracia ; Marin, E. ; Ruíz, A. ; Borque, María Jesús ; Gil, A. J. ; Biagi, L. | Springer | 2001Two new GPS surveys have been carried out to check the accuracy of an existing gravimetric geoid in a test area located in northern Andalusia (Spain). The fast collocation method and the remove-restore procedure have been used for the computatio[...]texto impreso
Marín-Lechado, Carlos ; Galindo-Zaldívar, Jesus ; Gil, Antonio José ; Borque, María Jesús ; Lacy de, María Clara ; Pradera, Antonio ; López-Garrido, Angel Carlos ; Alfaro, Pedro ; García-Tortosa, Francisco ; Ramos, María Isabel ; Rodríguez Caderot, Gracia ; Rodríguez-Fernández, José ; Ruiz-Constán, Ana ; Sanz De Galdeano-Equiza, Carlos | North American Technology | 2010The Campo de Dalias is an area with relevant seismicity associated to the active tectonic deformations of the southern boundary of the Betic Cordillera. A non-permanent GPS network was installed to monitor, for the first time, the fault- and fol[...]texto impreso
To estimate ionospheric delays from the Global Positioning System (GPS) measurements, satellite and receiver equipment biases have to be modeled. This paper presents a procedure based on the least squares (LS) approach, which implicitly takes in[...]texto impreso
Lacy de, María Clara ; Gil, Antonio José ; Rodríguez Caderot, Gracia ; Moreno, B. | Universidad Complutense de Madrid | 2008The modernization of the Global Positioning System (GPS)and the advent of the European Project Galileo will lead to a multifrequency Global Navigation Satellite System (GNSS). Single GNSS receiver observations could be used to estimate the ionos[...]texto impreso
The problem of phase ambiguity resolution in: global positioning system (GPS) theory is considered. The Bayesian approach is applied to this problem and, using Monte Carlo simulation to search over the integer candidates, a practical expression [...]
