STARGATE - System for Trusted And Reliable Galileo Authenticated Time Ecosystem

STARGATE covers the full chain from receiver requirements and design to implementation, testing, and user integration. The project develops a Galileo timing receiver aligned with EN 16605, validates it against the associated test suite, and integrates it into a representative timing server platform. The scope includes laboratory and simulated testing, demonstration in realistic conditions, and preparation for market uptake, ensuring readiness for deployment in operational environments.

Challenge & technical solution

Key challenges include guaranteeing timing integrity under degraded GNSS conditions, correctly processing Galileo Timing Service flags, and achieving robust performance without over-constraining receiver design. STARGATE addresses these by implementing a performance-based architecture combining TSM processing, T-RAIM integrity monitoring, OSNMA authentication and communication with timing servers for them to decide holdover strategies. Extensive simulation and record-and-replay testing are used to validate compliance with EN 16605, ensuring the final solution delivers reliable, trustworthy time even in adverse scenarios..
