Ionized by solar radiation, the ionosphere causes a phase rotation or time delay to trans-
ionospheric radio waves. Reconstruction of ionospheric electron density profiles with global …

Computerized ionospheric tomography (CIT) based on Global Navigation Satellite System
(GNSS) data is a worthwhile project. However, predominant issues like unevenly distributed …

A new tomographic method was developed with the main goal of mapping the ionosphere in
the region of Brazil. The ionospheric background was estimated based on ionosonde and …

Abstract Undifferenced and Uncombined Precise Point Positioning (UPPP) currently stands
as a prominent research area, where the integration of high-precision ionospheric products …

GNSS ionospheric tomography technique is capable to reconstruct the high-quality 3D
ionospheric electron density (IED) images with a relatively low cost. We present a new …

Total electron content measurements given by the global navigation satellite system (GNSS)
have successfully presented results to capture the signatures of equatorial plasma bubbles …

A new method for probing the spatial and temporal features of the topside ionosphere is
presented. The Vary‐Chap model given by linear functions was used to discover and report …

Spatial and temporal variation of the electron density in the atmosphere makes the
ionosphere a difficult region to model. A major difficulty arises due to the incomplete …

The inhomogeneous distribution of Global Navigation Satellite System (GNSS) data is a
significant problem for global GNSS computerized ionospheric tomography (CIT). By …

Global navigation satellite system (GNSS) measurements have become an outstanding data
source for ionospheric studies using total electron content (TEC) estimation procedures …
