The determination of a body position, velocity and attitude is the purpose of the navigation techniques. The most extended navigation systems (INS/GNSS), as any other HW and SW system, provide precise and accurate enough ...
Compared to the conventional ground measurement of gravity, airborne gravimetry is more efficient and cost-effective. Especially, the combination of GPS and INS is known to show very good performances recovering the gravity ...
Avui dia, s'estima que el mercat de la geom atica mou pels volts de 30 bilions d'euros. Al darrera del creixement d'aquest mercat hi trobem noves tecnologies,projectes i aplicacions, com per exemple, \Global Positioning ...
El sistema NAVSTAR/GPS ha desenvolupat un paper molt important en les tècniques de posicionament cinemàtic geodèsiques, especialment en la determinació de la trajectòries per a la orientació de sensors aerotransportats ...
The spatial decision-making process for the purpose of planning, policies, plans, or territorial programs, is intimately tied to the concept of location in the respective geographical space, mainly because many aspects ...
This thesis presents diverse theoretical and practical applications of the ERS 1/2 and RADARSAT satellite images of the Synthetic Aperture Radar SAR sensor (near 330 images in the Northwest Mediterranean NWM and 980 in ...
La tesis contiene en primer lugar un estudio de las técnicas de interferometria radiometrica, con énfasis en las causas de error y su impacto en las características del sensor. A continuación se proponen y comparan varias ...
Most galaxies have a warped shape when they are seen from an edge-on point of view. In this work we apply dynamical system methods to find an explanation of this phenomenon that agrees with its abundance among galaxies, ...
The study of solar radiation is a key process for the exploitation of solar energy systems. In most cases, however, the availability of information is insufficient and not up-to-date. In addition, the interpolation of ...
Los sistemas de posicionamiento global GNSS (GPS y GLONASS) se han convertido en una herramienta básica para obtener medidas geodésicas de la Tierra y en una fuente de datos para el estudio atmosférico. Proporcionan cobertura ...
La missió SMOS de l'Agència Europea de l'Espai (ESA) té com a objectiu mesurar la humitat del sòl i la salinitat dels oceans, paràmetres fonamentals per tal d'entendre el canvi climàtic global.<br/>MIRAS (Radiòmetre de ...
The research of this paper-based dissertation is focused on the Fast Precise Point Positioning (Fast-PPP) technique. The novelty relies on using an accurate ionosphere model, in combination with the standard precise satellite ...
New and future telecommunication networks are and will be broadband type. The existing terrestrial and space radio communication infrastructures might be supplemented by new wireless networks that make and will make use ...
Two research studies have been addressed in this thesis. Both of them are of actual scientific interest and are based on processing GNSS data. The first part of this thesis is devoted to GNSS detection and monitoring of ...
(English) This document presents the collection of four manuscripts published during my Doctoral academic formation, which main goal has been the real-time implementation of tools to monitor the ionosphere using Global ...
La tesi proposa una sèrie d'algoritmes destinats a obtenir informació del contingut d'electrons lliures presents a la ionosfera. El tipus de dades que s'utilitzaran seran bàsicament les corresponents a receptors de dades ...
Tot i que en les últimes dècades la reducció del soroll emès pels avions ha estat substancial, el seu impacte a la població ubicada a prop dels aeroports és un problema que encara persisteix. Contenir el soroll generat ...
The primary purpose of this thesis is the design, development and validation of a system capable of measuring magnetic field with low-noise conditions at sub-millihertz frequencies. Such instrument is conceived as a part ...
Due to the rich dynamic properties of the equilibria of the Restricted Three Body Problem (RTBP), the libration point orbits (LPOs) around them are ideal locations for scientific missions. Fortunately, these invariant ...
El present treball analitza l'aplicabilitat de diferents tècniques, originalment ideades per al tractament de xàfecs que fan ús d'imatges IR de satèl·lit per estimar la precipitació amb una finalitat climatològica en la ...
