Absolute Measurements in the Calibration Laboratory of the new Hangar of Cargolux

This report contains the results of absolute gravity measurements carried out in the calibration laboratory of the new hangar of Cargoluxin June 2009. The absolute gravimeter FG5#216 from the European Center for Geodynamics and Seismology was operated by Olivier Francis and Gilbert Klein from the University of Luxembourg. The main objective of the measurement was to provide a reference point where the absolute value of gravity is known with an accuracy of a few microgal (1 microgal = 10 nm/s**2 is equivalent to 10 -9 of g).
