We are pleased to announce the appointment of Lorenzo Ortega Espluga as Co-Chair of the Scientific Council. Through his expertise and commitment, he will contribute to the Council’s work and to the development of its thinking on major scientific challenges. As Co-Chair, he will work alongside the other members of the Scientific Council to help guide its activities, foster new research perspectives, and enhance the visibility of TéSA’s scientific work. We would also like to extend our sincere thanks to Riadh Dhaou for his commitment and for the work accomplished during his term as Chair.

We wish Lorenzo Ortega Espluga every success in his new role.

Following on from his PhD research, Hamish McPhee, now a postdoctoral researcher and still at TéSA, presented his work on the application of robust and misspecified estimation to time scale generation in a swarm of nanosatellites. It was a great opportunity for everyone to discover how onboard clocks can work together while remaining resilient to disturbances, …and to put their own synchronization skills to the test!

And it continues… Marta Bottani, a TéSA doctoral student, has won another award! She received the 1st prize for Best Student Paper at the IEEE CAMSAP 2025 international conference (IEEE International Workshop on Computational Advances in Multi-Sensor Adaptive Processing), which took place in December. Congratulations again!

Youssef Minyari, a PhD student at TéSA, won first prize for Best Student Paper at the IEEE ICSOS 2025 (IEEE International Conference on Space Optical Systems and Applications), held in Japan at the end of October, for his paper on “Robust MISO coherent optical GEO satellite feeder link with relaxed implementation constraints,” co-authored with Raphaël Le Bidan (IMT Atlantique), Charly Poulliat (Toulouse INP), and Aubin Lecointre (Thales Alenia Space).

One word: BRAVO!!!!!

For a first paper, this is a remarkable achievement!

Emile Ghizzo, a postdoctoral researcher at ISAE-SUPAERO, presented a seminar on GNSS signal processing under spoofing. It was a very interesting seminar that helped us understand the effects of these attacks on the GNSS signal and its processing. This is undoubtedly a current problem affecting many systems, including airliners that become lost and diverted, disrupting all air traffic. Thank you to Emile for this seminar!
