Open AccessGround Based Augmentation System (GBAS) is a version of Differential Global Positioning System (DGPS) designed to reliably support airplane's all phase of approach, landing, departure and surface operations. Local ionospheric ...
Improvement of the ionospheric radio occultation retrievals by means of accurate global ionospheric maps Shao, Yixie; González Casado, Guillermo; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; Rovira Garcia, Adrià (2018-12-22)
Restricted access - author's decisionThe Abel inversion method is the classic approach to retrieve electron density profiles from radio occultation measurements, assuming that the electron density is only dependent upon height. In the early 2000s, the total ...

Open AccessApplying a methodology developed and tested in previous studies, the contribution from the ionospheric and plasmaspheric regions to the total electron content (measured by ground receivers) is analyzed. ...
World-wide analysis and modelling of the ionospheric and plasmaspheric electron contents by means of radio occultations Shao, Yixie (Universitat Politècnica de Catalunya, 2019-02-25)
Open AccessThe research of this dissertation is studying the ionosphere by GPS radio occultation (RO) techniques. It is mainly divided into two parts. The first part focuses on the methodology in electron density profile retrievals ...
