Time Dissemination

The dissemination services are based on two systems: the telephone time code CTD (Codice Telefonico di Data) available on the telephone network, and the primary NTP (Network Time Protocol) on the Internet. Among the synchronization techniques, three GPS receivers, are used to grant for the traceability to UTC(IT) in the frame of the remote calibration of reference frequency sources located at Institutes and Industries.
