An analysis of the correlation between the fast variations in the total electron content of the ionosphere and the carrier phase fluctuations of radio signals from global navigation satellite systems
(Universitat Politècnica de Catalunya, 2021-06-22)
Master thesis
Open Accessonospheric scintillation consists on rapid fluctuations in the amplitude and phase of electromagnetic signals, which includes those of the Global Navigation Satellite System (GNSS), that can lead to cycle slips and even ... -
Analysis of ionospheric disruptions in GNSS signals from Tonga eruption
(Universitat Politècnica de Catalunya, 2022-07-13)
Master thesis
Open AccessThe Tonga volcano eruption at 04:15 UT on 2022-01-15 released enormous amounts of energy into the atmosphere, causing very significant geophysical variations not only in the immediate proximity of the epicenter but also ... -
Analysis of ionospheric scintillation in GNSS signals
(Universitat Politècnica de Catalunya, 2021-06-22)
Master thesis
Open AccessScintillation is a particular type of space weather disturbance that currently limits the accuracy and availability of the Global Navigation Satellite System. The present final master’s thesis aims to study the characteristics ... -
Analysis of the impact of ionospheric scintillation in GNSS-based positioning in the Arctic region
(Universitat Politècnica de Catalunya, 2020-11-27)
Master thesis
Open AccessAs the world becomes more complex rapidly having a smart infrastructure is a necessity to be able to manage them remotely by high accuracy. In order to cope with this issue we need to have precise navigation globally which ... -
Characterization of errors in orbits and clocks of GLONASS satellites
(Universitat Politècnica de Catalunya, 2021-10-21)
Master thesis
Open AccessSatellite navigation systems require of knowing satellite positions with a high level of accuracy. Unlike other GNSS constellations, GLONASS ephemeris can not be directly obtained from broadcast navigation messages at any ... -
Contributions to high accuracy snapshot GNSS positioning
(Universitat Politècnica de Catalunya, 2022-11-10)
Doctoral thesis
Open Access(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 ... -
Design and implementation of cycle-slip detectors for for Dual-frequency GNSS Signals
(Universitat Politècnica de Catalunya, 2016-03-16)
Master thesis
Open AccessIntroduction: Satellite navigation systems are widely used for today's high accuracy applications demanding the most accurate ranging information obtainable, which is the carrier phase observable. Before the carrier phase ... -
gLAB upgrade with EGNOS data processing
(Universitat Politècnica de Catalunya, 2016-06)
Master thesis (pre-Bologna period)
Open AccessgLAB is a free open-source software to process GNSS data. The first release of this software package allows full processing capability of GPS data, and partial handling of Galileo and GLONASS data. EGNOS is the european ... -
GNSS navigation under ionospheric scintillation conditions
(Universitat Politècnica de Catalunya, 2017-07-18)
Bachelor thesis
Open AccessThe aim of this document is to present an analysis of ionospheric scintillation occurrence and effects on GNSS systems. Refractive and diffractive effects have been compared in low and high latitudes using data from NovAtel ... -

(Universitat Politècnica de Catalunya, 2018-03-05)
Master thesis
Restricted access - author's decisionThe Global Navigation Satelite System, GNSS is a constellation of satellites orbiting around the Earth and transmitting signals that contain ranging codes and navigation data, allowing the user to compute its position and ... -
Study and optimization of transfer orbits to the L4 and L5 Lagrange Points of the Earth-Sun system
(Universitat Politècnica de Catalunya, 2023-02-06)
Bachelor thesis
Open AccessThe Circular-Restricted Three-Body Problem (CR3BP) describes the motion of a small celestial body in the gravitational field of two larger bodies. The present study focuses on the application of the CR3BP to the Sun-Earth ...
