TéSA was magnificently represented at the CNES JC2: Gastón de Boni Rovella explained to us with all his pedagogy and humor the workings of channel coding and his innovative approach using machine learning, Evelyne Akopyan brilliantly highlighted the issues of his PhD subject around resilient networks in nanosatellite swarms but it was Hamish McPhee (the third starting from the left) who won a prize by succeeding in making us understand the delicate problem of clock synchronization in nanosatellite swarms ! Well done to all three!
