  • Grotti, Jacopo (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    This work presents the first measurement campaigns performed with PTB transportable optical lattice clock based on Strontium atoms for applications in clock comparisons and relativistic geodesy.
  • Schilling, Manuel; Timmen, Ludger; Kumme, Rolf (Helsinki : IMEKO, 2017-06-01)
    The gravity acceleration g plays an important role in several physical quantities as provided by National Metrology Institutes. The unit of force is realized in dependence on g in force standard machines (FSM). We present ...
  • Schilling, Manuel; Timmen, Ludger (Cham : Springer, 2016-06-28)
    The absolute measurement of g is currently realized through the laser interferometric measurement of a free falling retro-reflector. The Micro-g LaCoste FG5X is a free-fall gravimeter with a laser interferometer in ...
