Con la proliferación del uso de los sistemas GNSS se ha hecho necesario, dada su enorme utilidad, la implantación por parte de diferentes organismos de redes GNSS de estaciones permanentes. Actualmente no se concibe trabajar en Geomática, Topografía o Geodesia sin el apoyo de las redes GNSS de estaciones permanentes. En 1994 W. Strange definió…
Cuando se procesan redes de alta precisión, tanto para estudios geodinámicos, como geodésicos, se hace necesaria la utilización de software científico como Bernese, este software contempla todos los factores que pueden modificar tanto los marcos de referencias como el procesamiento de los observables.
Los receptores GNSS son la interfaz de usuario a cualquier Sistema Global de Navegación por Satélite (GNSS) y su objetivo es procesar las Señales En el Espacio (SIS) transmitidas por los satélites. La mayoría de ellos se basan en soluciones de navegación del receptor que proporcionan posición, velocidad y tiempo. Las características principales de los receptores…
The Betic Cordillera is placed in the westernmost end of the Alpine Mediterranean belt and it is being deformed by the African and Eurasian convergence of the plates. The relative displacement between both plates in the Iberian Peninsula sector is approximately 4-5 mm / year in a NW-SE direction. This slow but constant approaching of the…
Land subsidence is a natural hazard that sometimes causes significant economic damage and great alarm. The causes of land subsidence are diverse and sometimes complex, and all lead to vertical deformations of the earth’s surface. These deformations can range from a few millimetres to several meters for periods ranging from minutes to years. This paper, in association…
Displacements and ground motions near volcanoes are one of the warning signs of volcanic eruptions. One of the most important tools to detect such movements is the technology provided by GNSS permanent stations network. This paper, in association with Albireo Topografia y Geomática, studies the use of GNSS techniques for the determination of the spatial and temporal displacements…
Sixty per cent of human deaths caused by natural disasters in the past decade were due to earthquakes. Earthquake monitoring has assumed great importance in recent scientific studies and one of the most recent additions to the numerous inter-disciplinary techniques employed for studying earthquakes are GNSS technologies. GNSS technologies and permanent station networks have created…
