INRiM disseminates UTC(IT) and traceable frequency references through multiple channels matched to user requirements. Internet users are served through monitored NTP services, while higher-performance applications use calibrated satellite techniques based on GNSS and Two-Way methods. Where fiber is available, INRiM develops optical-fiber dissemination and synchronization solutions, including White Rabbit/PTP approaches for distributed facilities. 

The current plan foresees new synchronization services in optical fiber and via GNSS and alternative solutions, explicitly aimed at providing resilience and traceability for critical infrastructures. The planned Matera laboratory (connected to Torino through GNSS and fiber) supports service continuity, geographical diversification and validation of different end-to-end synchronization techniques.
