Application of tomographic ionospheric corrections in WADGPS networks for real-time estimation of integrated water vapour
(Instituto de Navegacion de España, 2021)
Conference report
Open AccessIn recent years several authors have developed strategies that estimate the Integrated Water Vapor (IWV), proportional to the Zenith Tropospheric Delay (ZTD), in near real time --i.e. with a delay of one hour or more--. ... -
Long-baseline (> 400Km) on the fly ambiguity resolution using ionospheric corrections with high geomagnetic activity
(2001)
Conference lecture
Open AccessA procedure for resolving carrier phase ambiguities, even under unfavorable geomagnetic conditions, has been tested. Precise ionospheric corrections have been made using dual-frequency data from control stations. Successful ... -
Assessment of St. Patrick's Day 2015 Geomagnetic storm impact on EGNOS
(European Space Agency (ESA), 2015)
Conference lecture
Restricted access - publisher's policyThe Monitor project has been designed to monitor ionospheric events that would allow evaluating its impact on European GNSS Systems. It includes a network of ionospheric scintillation monitoring stations in various ... -
Global distribution of ionospheric scintillations from the Real-Time GPS ROTI
(2018)
Conference lecture
Open AccessA global real-time monitoring system has been implemented in the frame of ESA-ESTEC/EGNOS-POfunded project MONITOR. It is based on world-wide GNSS datastreams distributed by means of NTRIP and provides multiple ionospheric ... -
Recent activities of IAG working group “Ionosphere Prediction”
(2018)
Conference lecture
Open AccessIonospheric disturbances pose, for instance, an increasing risk on economy, national security, satellite and airline operations, communications networks and the navigation systems. Constructing ... -
St. Patrick’s Day 2015 geomagnetic storm analysis based on Real Time Ionosphere Monitoring
(2017)
Conference lecture
Open AccessA detailed analysis is presented for the days in March, 2015 surrounding St. Patrick’s Day 2015 geomagnetic storm, based on the existing real-time and near real-time ionospheric models (global or regional) within the ... -
Ionosphere monitoring and forecast activities within the IAG working group “Ionosphere Prediction”
(2017)
Conference lecture
Open AccessIonospheric disturbances can affect technologies in space and on Earth disrupting satellite and airline operations, communications networks, navigation systems. As the world becomes ever more dependent on these technologies, ... -
The Stanford-ESA integrity diagram: focusing on SBAS integrity
(ION Publications (The Institute of navigation), 2016)
Conference lecture
Restricted access - publisher's policyIn this article, a new concept for SBAS integrity validation is presented. The proposed concept is a modification of the well known Stanford diagram [2], where a 2D histogram shows the relationship of position errors against ... -
Real time global ionospheric maps: a low latency alternative to traditional GIMs
(2016)
Conference lecture
Restricted access - publisher's policySince the late nineties different entities have been generating and distributing Global Ionospheric Maps (GIMs). In this time, multiple new application have arisen from the determination of electron content distribution ... -
Comprehensive ionospheric delay modelling for single-frequency GNSS precise positioning: first steps
(International GNSS Service (IGS), 2016)
Conference lecture

Assessment of the F2-layer electron density peak inferred from Formosat-3/COSMIC radio occultations over half a Solar Cycle
(2016)
Conference report
Restricted access - publisher's policyGNSS radio occultation (RO) measurements have become crucial to provide valuable information on the vertical electron density structure of the Ionosphere. Ionospheric key parameters such as the maximum electron density ... -
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 ...
