Dr Jian Wang is currently a Visiting Fellow at the School of Surveying and Spatial Information Systems, University of New South Wales (UNSW). He graduated with a PhD from China University of Mining & Technology (CUMT) in 2006. His area of expertise is in the field of GNSS/INS integration with special emphasis on the quality control of navigation. He also focuses on the studies of wavelet theory...

Global Navigation Satellite System (GNSS)-based ionospheric anomalies are nowadays used to identify a possible earthquake (EQ) precursor and hence new research topic in seismic studies. The current study also aims provide an investigation of associated EQs. In order pre-and post-seismic perturbations during the preparation phase large-magnitude EQs, statistical machine learning algorithms appli...

This work presents, for the first time, analysis of occurrence ionospheric irregularities during geomagnetic storms at Tucumán, Argentina, a low latitude station in Southern American longitudinal sector (26.9°S, 294.6°E; magnetic 15.5°S) near southern crest equatorial ionization anomaly (EIA). Three occurred on May 27, 2017 (a month rates spread-F), October 12, 2016 transition from to high spre...

Ionospheric tomography is a method to investigate the ionospheric electron density in two or three dimensions. In this study, the function-based tomographic technique has been used for regional reconstruction of a 3D tomographic model of the ionospheric electron density using the GPS measurements of the Iranian Permanent GPS Network. Two-dimensional Haar wavelets and empirical orthogonal functi...
