The Italian Standard Time

UTC(IT), the Italian realization of UTC, is generated starting from one of the AHM (the best behaving is chosen as “Master Clock”, MC), whose frequency offset and drift are compensated by means of a dedicated devices (called micro-stepper) and specific algorithms . A project for new UTC(IT) time scale generation is under development to improve its reliability, through a totally autonomous system. From the same MC, a further time scale is generated, namely the Experimental Galileo System Time (EGST) used as reference for a Galileo Experimental Sensor Station (GESS) hosted at the INRIM Radio Navigation Laboratory (RNL).
