Simultaneous Radio Occultation Predictions for Inter-Satellite Comparison of Bending Angle Profiles from COSMIC-2 and GeoOptics

open access: yesRemote Sensing, 2021
The Global Navigation Satellite System (GNSS) radio occultation (RO) is a remote sensing technique that uses International System of Units (SI) traceable GNSS signals for atmospheric limb soundings.

On the Feasibility of Interhemispheric Patch Detection Using Ground-Based GNSS Measurements

open access: yesRemote Sensing, 2018
Dual-frequency GNSS data processing is currently one of the most useful techniques for sounding the ionosphere. Hence, this work was aimed at the evaluation of ground-based GNSS data for the continuous monitoring of polar patches in both hemispheres.

The role of particle precipitation on plasma structuring at different altitudes by in-situ measurements

open access: yesJournal of Space Weather and Space Climate, 2023
The plasma in the cusp ionosphere is subject to particle precipitation, which is important for the development of large-scale irregularities in the plasma density.
