Aeronautical Air-Ground Data Link Communications

MOHAMED SLIM BEN MAHMOUD is a researcher and an associate professor at the French Civil Aviation University (Ecole Nationale de l'Aviation Civile - ENAC), Toulouse, France. He is a full time member of the TELECOM/ResCo research team, his major research contributions are related to network security engineering with a particular focus on the Aeronautical Communication Networks (ATN). He is also involved in the Single european Sky ATM Research (SESAR) project where future data link technologies are being defined.CHRISTOPHE GUERBER is an engineer, data link teacher and networks at ENAC. He took part during his career in the definition, validation and implementation of the data link in europe. As a member of the European and international standardization and standardization groups, he worked with French and European air navigation organizations. He also participated in the definition of avionics systems for embedded ATC data link applications.NICOLAS LARRIEU is an associate professor at the research group ResCo at the TELECOM laboratory of ENAC (French Civil Aviation University). He is graduated from INSA of Toulouse where he got a PhD in Computer Science in 2002.His research topics deal with designing new communication architectures and original security architectures for emerging networks such as IP-based aeronautical communication networks or UAV communication networks. His is currently involved in several work activities of the SESAR European program where he can extend and validate his research results.ALAIN PIROVANO is a teacher / researcher and head of the ResCo research group at ENAC (TELECOM laboratory). These lessons and his research focus mainly on communication networks, particularly in the aeronautical and satellite fields. He is involved in several research programs including SESAR (Single European Sky ATM Research).JOSÉ RADZIK is a teacher-researcher at the DEOS (Electronics Optronics Signal) department of ISAE (Institute Superior of Aeronautics and Space). He is involved in research programs related to satellite communications. He is responsible for the option "Telecommunications and Satellite Networks" of the SUPAERO Ingenieur Training.
