Multi-satellite cycle-slip detection and exclusion using the noise subspace of residual dynamics
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyReal-time detection of cycle-slips on undifferenced carrier-phase measurements is an important task to properly exclude wrong phase trackers from precise positioning algorithms. The detection is especially challenging in ... -
The GNSS Laboratory Tool Suite (gLAB) updates: SBAS, DGNSS and Global Monitoring System
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Restricted access - publisher's policyThis work presents recent and ongoing updates to the free and open-source advanced interactive multi-purpose package for processing and analysing Global Navigation Satellite System (GNSS) data, named GNSS-Lab Tool suite ... -
Improvement of the ionospheric radio occultation retrievals by means of accurate global ionospheric maps
(2018-12-22)
Article
Restricted access - author's decisionThe Abel inversion method is the classic approach to retrieve electron density profiles from radio occultation measurements, assuming that the electron density is only dependent upon height. In the early 2000s, the total ... -
Improved modelling of ionospheric disturbances for remote sensing and navigation
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Conference report
Restricted access - publisher's policyA generic software tool to evaluate the impact of ionospheric disturbances is presented, including low and high latitude physically-based models, and low and high frequency fluctuations. This tool has been developed ... -

Ionospheric scintillation monitoring using GNSS-R?
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyThe characterization of the ionosphere and its impact on the propagation of radio-wave signals has received an increasing interest for satellite communications, Global Navigation Satellite Systems (GNSS) applications (i.e. ... -
Revisit the calibration errors on experimental slant total electron content (TEC) determined with GPS
(2018-06-26)
Article
Open AccessThe calibration errors on experimental slant total electron content (TEC) determined with global positioning system (GPS) observations is revisited. Instead of the analysis of the calibration errors on the carrier phase ... -
Improved characterization and modeling of equatorial plasma depletions
(2018-08-22)
Article
Open AccessThis manuscript presents a method to identify the occurrence of Equatorial Plasma Bubbles (EPBs) with data gathered from receivers of Global Navigation Satellite System (GNSS). This method adapts a previously existing ... -

Feasibility of precise navigation in high and low latitude regions under scintillation conditions
(2018-02-06)
Article
Open AccessScintillation is one of the most challenging problems in Global Navigation Satellite Systems (GNSS) navigation. This phenomenon appears when the radio signal passes through ionospheric irregularities. These irregularities ...
