Combining Swarm Langmuir probe observations, LEO-POD-based and ground-based GNSS receivers and ionosondes for prompt detection of ionospheric earthquake and tsunami signatures: Case study of 2015 Chile-Illapel event
(2021-12-08)
Article
Open AccessThe study investigates ionospheric electric field responses to the earthquake (EQ) of magnitude 8.3, and the related seismic activity and tsunami triggered by the mainshock in Chile-Illapel region, at 22:54 UTC, in the ... -
Correlation studies for B-spline modeled F2 Chapman parameters obtained from FORMOSAT-3/COSMIC data
(2014)
Article
Open AccessThe determination of ionospheric key quantities such as the maximum electron density of the F2 layer NmF2, the corresponding F2 peak height hmF2 and the F2 scale height HF2 are of high relevance in 4-D ionosphere modeling ... -
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 ... -
High-resolution ionosphere corrections for single-frequency positioning
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-01)
Article
Open AccessThe ionosphere is one of the main error sources in positioning and navigation; thus, information about the ionosphere is mandatory for precise modern Global Navigation Satellite System (GNSS) applications. The International ... -
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, ... -
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 ... -
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 ... -
Towards an optimal overall description of electron density information gathered during GNSS satellite occultations
(2014)
Conference lecture
Restricted access - publisher's policyThe purpose of this work is to characterize the performance of different interpolation methods in order to build a global model of ionospheric free electron density, directly derived from the inversions of GNSS occultation ...
