Long-distance chronometric leveling with a portable optical clock
J. Grotti, I. Nosske, S. B. Koller +19
We have measured the geopotential difference between two locations separated by by comparison of two optical lattice clocks via an interferometric fiber link, uti…
Calibration of a superconducting gravimeter with an absolute atom gravimeter
S. Merlet, P. Gillot, B. Cheng +4
We present a 27-days long common view measurement of an absolute cold atom gravimeter (CAG) and a relative iGrav superconducting gravimeter, which we use to calibrate the iGrav sca…
Gravity field modelling for the Hannover 10m atom interferometer
Manuel Schilling, Étienne Wodey, Ludger Timmen +6
Absolute gravimeters (AG) are used in geodesy, geophysics, and physics for a wide spectrum of applications. Stable gravimetric measurements over timescales from several days to dec…
Direct comparisons of European primary and secondary frequency standards via satellite techniques
F. Riedel, A. Al-Masoudi, E. Benkler +46
We carried out a 26-day comparison of five simultaneously operated optical clocks and six atomic fountain clocks located at INRIM, LNE-SYRTE, NPL and PTB by using two satellite-bas…
Geodesy and metrology with a transportable optical clock
Jacopo Grotti, Silvio Koller, Stefan Vogt +21
The advent of novel measurement instrumentation can lead to paradigm shifts in scientific research. Optical atomic clocks, due to their unprecedented stability and uncertainty, are…
Comparison between two mobile absolute gravimeters: optical versus atomic interferometers
S. Merlet, Q. Bodart, N. Malossi +4
We report a comparison between two absolute gravimeters: the LNE-SYRTE cold atoms gravimeter and FG5#220 of Leibniz Universität of Hannover. They rely on different principles of op…
