GNSS tomography resolution matrix spread - another overly complicated solution to simple problem?

05-05-2022

GNSS tomography is a technique that is looking into using observation penetrating the medium from multiple of angles to establish the 3D structure of that medium. This is inverse Radon transform, used in many - mostly medical applications (PET/CT scanning). Similar is done with GNSS observations that penetrates the atmosphere from multiple angles, accumulated impact of the atmosphere on the signal phase is recorded at the antenna point, and then inverted to produce 3D structure of atmosphere. Fairly simple, however the inversion is not always successful and the resultant 3D model becomes blurry or contains a lot of outliers.

When it happens? Why it happens? How to test for potentially unstable solution before running Radon inversion?

OPENSENSE COST Action – Call for Conference Grant Applications

14-03-2022

IGiG team members (Dr Tomasz Hadaś, Dr Jan Kapłon, MSc Estera Trzcina) have joined a EU COST Action OPENSENSE No. CA20136 "Opportunistic precipitation sensing network" for a period 2021-2025. The action aims to establish a network of opportunistic precipitation sensors (OS) and to lead coordinated activities to deepen and promote knowledge about the use of OS in determining the location and intensity of the precipitation.
