Experimental evidence of swell signatures in airborne L5/E5a GNSS-reflectometry
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-05-29)
Article
Accés obertAs compared to GPS L1C/A signals, L5/E5a Global Navigation Satellite System-Reflectometry (GNSS-R) improves the spatial resolution due to the narrower auto-correlation function. Furthermore, the larger transmitted power ... -
Fast LAMBDA-based ambiguity resolution combined with WARTK technique for Galileo data simulated using ESA's Galileo Signal Validation Facility
(2009-12)
Text en actes de congrés
Accés restringit per política de l'editorialThis contribution addresses the effect of having a triple frequency Global Navigation Satellite System (GNSS) on ambiguity resolution of long baselines, i.e. baselines for which the differential ionospheric delays cannot ... -
First experimental evidence of wind and swell signatures in L5 GPS and E5A Galileo GNSS-R waveforms
(2020)
Text en actes de congrés
Accés obertAs compared to the using L1C/A signals, L5/E5a Global Navigation Satellite System - Reflectometry (GNSS-R), gives improved resolution over the Earth's surface due to the sharper auto-correlation function. Furthermore, the ... -

(Multidisciplinary Digital Publishing Institute (MDPI), 2020-11-29)
Article
Accés obertA preliminary analysis of Galileo F/NAV broadcast Clock and Ephemeris is performed in this paper with 43 months of data. Using consolidated Galileo Receiver Independent Exchange (RINEX) navigation files, automated navigation ... -
Galileo Ionospheric Correction Algorithm Integration into the Open-Source GNSS Laboratory Tool Suite (gLAB)
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-07)
Article
Accés obertUsers of the global navigation satellite system (GNSS) operating with a single-frequencyreceiver must use an ionospheric correction algorithm (ICA) to account for the delay introduced onradio waves by the upper atmosphere. ... -
Galileo ionospheric correction algorithm: an optimization study of NeQuick-G
(2019-11-24)
Article
Accés obertAt present most low-cost GNSS receivers operate one frequency in the L band. For themone of the largest error contributions is the delay of radio signals in the Ionosphere. NeQuick-Gisthe official ionospheric correction ... -
