چکیده
Résumé. Nous présentons dans le présent document une vue d’ensemble du projet de détermination directe de la constante de von Klitzing RK, en cours de réalisation au Bureau International de Poids et Mesures (BIPM). Cette détermination est effectuée dans le contexte général de la révision du Système International d’unités qui sera effective à partir de 2018. L’objectif visé est de mesurer avec une incertitude relative réduite à 1.10. Pour cela un nouveau condensateur calculable a été réalisé et une chaine de mesure dédiée implémentée.

Towards a Determination of RK in Terms of the New LNE Calculable Cross Capacitor
In the scope of a possible redefinition in the SI, the LNE has decided to develop a new Thompson Lampard calculable capacitor to decrease its uncertainty on the value of von Klitzing constant, RK, to a level of one part in 10. This paper gives an overview of the French experiment. The main characteristics of the new French standard are detailed. The fabrication of a new set of electrodes and re...
متن کاملNIST Comparison of the Quantized Hall Resistance and the Realization of the SI OHM Through the Calculable Capacitor
Tbe latest NIST result from the comparison of the quantized Hall resistance (QHR) with the realization of the SI ohm obtained from the NIST calculable capacitor is reported. A small difference between the 1988 result and the present result has led to a re-evaluation of the sources and magnitudes of possible systematic errors.
متن کاملProgress in Carrier Phase Time Transfer
The progress of the joint Pilot Project for time transfer, formed by the International GPS Service (IGS) and the Bureau International des Poids et Mesures (BIPM), was recently reviewed. Three notable milestones were set. 1) The IGS will implement, at least in a test mode, an internally realized time scale based on an integration of combined frequency standards within the IGS network. This will ...
متن کاملIGS/BIPM pilot project: GPS carrier phase for time/frequency transfer and timescale formation
The development within the International GPS Service (IGS) of a suite of clock products, for both satellites and tracking receivers, offers some experiences which mirror the operations of the Bureau International des Poids et Mesures (BIPM) in its formation of TAI/UTC but some aspects differ markedly. The IGS relies exclusively on the carrier phase-based geodetic technique whereas BIPM time/fre...
متن کاملEstablishing Control Limits on Time Performance Indicators of Projects through Monte Carlo Simulation and Earned Duration Management
Earned Duration Management (EDM) method has been developed to enhance Earned Value Management and to solve some of its problems, such as separation of measuring time and cost dimensions. By providing performance indicators, this method makes it possible for managers to accurately measure the progress of a project and to calculate the time and cost required to complete it. Nevertheless, the acce...
