Centre National d'Etudes Spatiales CNES - 10/18/2016


Compact anti-decoying system of GNSS signals, allowing a distant and secure control of the integrity of the GNSS data time / positions.


Adaptability & modularity - Allow to apply the process to terminals having only the capacities of smartphone / car / payment terminals. Security - Detection of spoofing.


Authentification of GNSS / GPS signals - Time/position data-crossing. - Anti-decoying system / ARP spoo ng Secure method - Control sequences generated by pseudorandom code produced by an encryption key . - Certification of data authenticity. Compact - Device easily joined on small antenna supports.
