918-t Annual Precise Time and Time Interval (PTTI) Meeting COMPARISON OF ATOMIC FREQUENCY STANDARDS AT NIST AND PTB USING CARRIER- PHASE GPS

Abstract

We have constructed a link between Physikalisch-Techniche Bundesanstalt (PTB) in Braunschweig, Germany and the National Institute of Standards and Technology (NIST) in Boulder, Colorado using carrier-phase Global Positioning System (GPS) receivers. The link will provide a direct measurement of the frequency difference between UTC(PTB) and UTC(NIST), and can… (More)
