In a highly competitive call, SAPHYRION was selected by the EU Commission to participate to the Horizon Europe project  GAUSSIAN, a challenging initiative aiming wants to demonstrate the value of the authenticated Galileo E1 signals combined to integrated GNSS/INS platforms to have greater robustness against spoofing attempts and better continuity and availability of PNT data in constrained environments. SAPHYRION chips are a key element enabling to exploit the “differentiators” of GALILEO in a world-first solution.
