  • Rolfes, I.; Will, B.; Schiek, B. (Göttingen : Copernicus GmbH, 2008)
    With the availability of multi-port vector network analyzers, the need for automated, calibrated measurement facilities increases. In this contribution, a calibrationmeasurement unit is presented which realizes a repeatable ...
  • Sudhoff, Martin; Linsinger, Matthias; Schulte, Daniel; Kuhlenkötter, Bernd (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2020)
    In contrast to automated machines and installations, manual assembly still lacks real-time process monitoring and possibilities for short-term control and adaptation of assembly systems. This article describes an approach ...
  • Guéna, J.; Weyers, S.; Abgrall, M.; Grebing, C.; Gerginov, V.; Rosenbusch, P.; Bize, Sebastien; Lipphardt, B.; Denker, H.; Quintin, N.; Raupach, S.M.F.; Nicolodi, D.; Stefani, F.; Chiodo, N.; Koke, S.; Kuhl, A.; Wiotte, F.; Meynadier, F.; Camisard, E.; Chardonnet, C.; Le Coq, Y.; Lours, M.; Santarelli, G.; Amy-Klein, A.; Le Targat, R.; Lopez, O.; Pottie, P.-E.; Grosche, G. (Bristol : Institute of Physics Publishing, 2017)
    We report on the first comparison of distant caesium fountain primary frequency standards (PFSs) via an optical fiber link. The 1415 km long optical link connects two PFSs at LNESYRTE (Laboratoire National de métrologie ...
  • Battermann, S.; Trautnitz, F.W.; Garbe, Heyno (Göttingen : Copernicus GmbH, 2005)
    Standards for the validation of alternative test sites with conducting groundplane exist for the frequency range 30-1000 MHz since the end of the eighties. Recently the procedure for fully anechoic rooms (FAR) has ...
  • Flury, Jakob (Bristol : Institute of Physics Publishing, 2016)
    Quantum metrology enables new applications in geodesy, including relativistic geodesy. The recent progress in optical atomic clocks and in long-distance frequency transfer by optical fiber together pave the way for using ...
