Alpbach Summer School 2022
08-08-2022
Adam Cegła - PhD student at IGIG UPWr took part in the Summer School in Alpbach, Austrian Tirol, organized by the Austrian Research Promotion Agency (FFG) and the European Space Agency (ESA). The theme of the Summer School was plasma physics in universe.
MSc. Adam Cegła with his 14-person team planned the cost estimate and the course of the mission to Mars to study the planets magnetosphere. This project was recognized as the best by the members of the jury and received an honorable mention along with an invitation to ESA specialized workshops at the ESEC-Galaxia training center in Belgium.

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?
