Time and Frequency Activities at the Physikalisch-Technische Bundesanstalt

Abstract

PTB is entrusted to provide legal time for Germany and is serving as the European node for time comparisons among institutes collaborating with the BIPM in the realization of TAI. Recent activities pursued in this context were directed towards an improved knowledge of internal delays of PTB's time comparison equipment. The standard frequency and time signal transmission via DCF77 remains the most important means to disseminate legal time, and we report on some new ideas for additional use of the broadcast signal. As the foundation of our work, we continued the operation of the primary clocks CS1 and CS2, and of the cold-atom cesium fountain CSF1.
