A linear scale height Chapman model supported by GNSS occultation measurements
(2016-05)
Conference lecture
Open AccessGlobal Navigation Satellite Systems (GNSS) radio occultations allow the vertical sounding of the Earth's atmosphere, in particular, the ionosphere. The physical observables estimated with this technique permit to test ... -
A method for scintillation characterization using geodetic receivers operating at 1 Hz
(2017-05-08)
Article
Open AccessIonospheric scintillation produces strong disruptive effects on global navigation satellite system (GNSS) signals, ranging from degrading performances to rendering these signals useless for accurate navigation. The current ... -
Assessment of Ionospheric Corrections Algorithms Using the GNSS Laboratory Tool Suite (gLAB): From STEC to Navigation Performance
(ION Publications (The Institute of navigation), 2020)
Conference report
Restricted access - publisher's policyUsers of the Global Navigation Satellite System (GNSS) using a single-frequency receiver need to use an Ionospheric Correction Algorithm (ICA) to compensate the delay introduced by the Ionosphere on radio waves. The European ... -
Electron density extrapolation above F2 peak by the linear Vary-Chap model supporting new Global Navigation Satellite Systems-LEO occultation missions
(2017-08)
Article
Open AccessThe new radio-occultation (RO) instrument on board the future EUMETSAT Polar System-Second Generation (EPS-SG) satellites, flying at a height of 820 km, is primarily focusing on neutral atmospheric profiling. It will also ... -
Evaluation of the ionospheric F2 characteristics inferred from radio occultations exploiting the availability of FORMOSAT-3/COSMIC data over half a solar cycle
(ION Publications (The Institute of navigation), 2016)
Conference report
Restricted access - publisher's policyThis contribution presents the assessment, on both the maximum electron density (NmF2) and the corresponding peak height of the F2 layer (hmF2), of the overall performance of such ionospheric key parameters inferred from ... -
Galileo Ionospheric Correction Algorithm Integration into the Open-Source GNSS Laboratory Tool Suite (gLAB)
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-07)
Article
Open AccessUsers 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
Open AccessAt 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 ... -
Polar electron content from GPS data-based global ionospheric maps: assessment, case studies, and climatology
(2020-04-22)
Article
Open AccessThe electron content distribution of the north and south polar ionosphere from 2001 to the beginning of 2019 is analyzed by using the UQRG global ionospheric map (GIM) of vertical total electron content (VTEC), computed ... -
Precise time series determination in the European Sea Level (ESEAS) project
(Institut de Geomàtica, 2005)
Conference report
Open AccessIn the framework of the European Sea Level service (ESEAS) project, 4 years time series has been computed using the Precise Point Positioning (PPP) approach. The processing has been carried out using both, the IGS and JPL ...
