GIANO

Galileo-based TIming Receiver for CriticAl INfrastructure RObustness

GNSS technology is currently widely used by Timing and Synchronisation user community because capable to provide timing services granting time, phase and frequency network synchronisation. 

In an increasingly complex GNSS environment, the unavailability of synchronisation due to unintentional or deliberate interferences and/or spoofing of GNSS signal can cause economic losses due to disruption of the services. 

The GIANO project aimed to develop a technological solution capable to make critical infrastructure more robust against interference, jamming, and spoofing, and increase the accuracy and reliability of the time transfer service. 

Thus, by leveraging Galileo and EGNOS-driven innovation, the GIANO project developed a solution that addresses the need of improved resilience and robustness by the critical infrastructure user community, especially energy generation and distribution, telecommunications, and financial operators. 

The GIANO project aims to successfully bring Galileo and EGNOS driven innovation to the GNSS‐based timing and synchronisation domain. 

As a result, the GIANO project developed a multi-GNSS timing receiver fulfilling both the accuracy and robustness needs of several timing applications. 

The resulting Galileo‐based timing platform represents a tangible test bench for innovation to be industrialised, by tailoring it towards each specific application and user need.

Challenge and technical solution

The developed solution exploits state-of-the-art multi-GNSS (GPS/Galileo & EGNOS), multi-frequency (L1/E1, L5/E5a, E6) with high Radio Frequency flexibility. 

This was achieved through an innovative Direct-Sampling and Digital Down-Conversion approach. 

By leveraging Galileo OS authentication and Time-Receiver Autonomous Integrity Monitoring (T-RAIM) algorithms, the GIANO platform enables resilience and time integrity against Jamming and Spoofing threats.
