In addition to its service provision, the GSA is also responsible for ensuring that Europe’s GNSS signals are secure. Within this function, the GSA is undertaking security accreditation of the complete Galileo system, its operations and services – including the Galileo Open Service, Commercial Service and Public Regulated Service (PRS).
All security-related work is overseen by the independent Security Accreditation Board (SAB). The SAB is hosted by the GSA, and assesses the robustness and resilience of both Galileo and EGNOS and all the services they offer. It is comprised of security experts from each EU Member State.
As a result of this focus on security, the GSA is increasing end-user confidence that European GNSS services are available in a secure, resilient and reliable manner.
