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!
