Abstract
This paper describes the present status of the determination of the von Klitzing constant R K with a target relative uncertainty of 1 part in 10 8 . The last improvements of the measurement chain operating at the required uncertainty and the latest changes to the new calculable capacitor under construction at LNE are presented.
