Session - Modelling the Earth's ionosphere and solutions to counter ionospheric threats to GNSS applications

Marcio Aquino, Alan Dodson (Monday) and Giorgiana De Franceschi, Vincenzo Romano (Tuesday)

The Earth's ionosphere is a complex system that is driven by many different factors such as solar radiation, electric and magnetic fields, and neutral atmosphere dynamics. New models and data to realise the state of the Earth's ionosphere are of interest to radio system users whose signals are affected by ionospheric propagation, in particular navigation and communications systems operating below 3 GHz. Global Navigation Satellites Systems (GNSS), which have become essential in support of a growing number of activities now embedded in modern society, are especially vulnerable to signal propagation through the ionosphere. In this context this session addresses models and solutions to mitigate ionospheric threats to GNSS and related applications. The TRANSMIT project, an FP7 funded Marie Curie Initial Training Network, has focused on the understanding and development of new models that can be tested for their usefulness in addressing radio system specification with a view to support the development of concepts and operational tools that could contribute to a service to assist European users in countering GNSS vulnerability to ionospheric phenomena. Results of this project are expected to be showcased in this session, as well as any other initiatives in this area. The session welcomes work in the areas of ionospheric tomography and imaging, radio occultation, scintillation and interference resilient receiver tracking models and implementations, real time positioning algorithms (e.g. for Precise Point Positioning) to mitigate ionospheric threats affecting legacy and new GNSS signals, scintillation and TEC prediction models and operational tools, as well as any other related topics. The main aim of the session is to stimulate discussion and encourage new collaborative work.

Kees de Jong
The session chairs are deeply sad to inform you of the sudden passing of our invited speaker Kees de Jong from Fugro Intersite B.V. (The Netherlands) on 31st October. Kees was an unconditional supporter of the TRANSMIT project and became not only a fantastic professional advisor to all of us, but also a great friend and colleague. Our thoughts are with his family and friends.
