Rovira Garcia, Adrià (Date of defense: 2016-01-21)
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 ...
Jové Casulleras, Roger (Date of defense: 2015-02-17)
The submitted Ph.D. thesis is a contribution to the development of pico-satellites and nano-satellites for Earth Observation and Technology Demonstrators. Development of satellites with a mass from 1 kg up to 10 kg has ...
Carreno-Luengo, Hugo (Date of defense: 2016-01-21)
Global Navigation Satellite Systems Reflectometry (GNSS-R) is a multi-static radar using navigation signals as signals of opportunity. It provides wide-swath and improved spatio-temporal sampling over current space-borne ...
Liu, Xiao (Date of defense: 2022-11-10)
(English) Snapshot positioning is the technique to determine the position of a Global Navigation Satellite System (GNSS) receiver using only a very brief interval of the received satellite signal. In recent years, this ...
García Rigo, Alberto (Date of defense: 2012-12-17)
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 ...
Lyu, Haixia (Date of defense: 2020-11-17)
This dissertation focuses on determining the vertical electron content distribution in low and high vertical resolution from ground-based and LEO on board GNSS data and improving the knowledge of ionosphere climatology in ...
García Fernández, Miquel (Date of defense: 2004-03-15)
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 ...
Wis Gil, Mariano (Date of defense: 2016-11-02)
Es ampliamente conocido que los modelos de error para sensores inerciales tienen dos componentes: El primero es un componente determinista que normalmente es calibrado por el fabricante en el firmware de la IMU. El segundo ...
Fedi Casas, Manrico (Date of defense: 2015-04-24)
This thesis is focused on the study of dynamics and control of a multi-tethered satellite formation, where a multi-tethered formation is made up with several satellites (agents) connected by means of cables (tethers). The ...
