Abstract :
In the course of the year 2007, UTC(CH) will change from a computed time scale definition to one based on a realtime master clock. In preparation for this important change, the time scale generation hardware was upgraded and new control software is being developed. This paper discusses recent progress in the development of control and calibration methods used in the new time scale generation system and reports experimental results obtained during validation testing.
