Update on Time and Frequency Activities at PTB

Abstract

The activities in the field of time and frequency metrology pursued at PTB are reviewed. Among the recent milestones have been the development and quasi-continuous operation of a cesium fountain frequency standard, the realization of a free atomic time scale TAF (PTB) based on the fountain results, and the cooperation in international time comparison projects using GPS carrier-phase receivers and TWSTFT in Ku-band and X-band.
