Despliegue de estaciones GPS permanentes en el marco del proyecto Topo-Iberia

Abstract

Topo-Iberia is the short name of a Spanish Research Council funded project. lts main objective is to understand interactions among deep, shallow and atmospheric processes, integrating geological, geophysical, geodetic and geotechnological researching activities. Knowledge of topographic changes and their causes are needed in order to assess natural hazards. It is also important to take them into account when evaluating the climatic change impact. The project will be focused in three main areas of interest, located in the Iberian Peninsula: Northern and Southern borders of the lberian micro-plate, as well as its central core. However, the Southern border does not imply that the Northern Moroccan behaviour is not taken into account. This paper will show the preliminary steps that the Topo-Iberia GPS working group is undergoing in order lo deploy a new Continuous GPS Network at Spain and Morocco. We are trying to complement the airead y existing and functioning CGPS Networks (e.g. ROA, ERGPS) by increasing the spatial coverage across Spain and Northern Morocco. While the purchasing procedures have beenfollowed, the places for the new locations have been chosen. A set of available CGPS data files has been downloaded from different institutional servers. A preliminary data analysis has been performed as a maller of geodetic quality control. Since some of the existing CGPS stations have been installed without fol/owing strict lGS/EUREF procedures for the stability of the monumenls, we are investigating their performance through the time series analysis, in order to decide whether to include them as complementing stations to the Topo-Iberia network.
