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…
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 o…
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…
