Absolute gravity measurements at the Conrad Observatorium in Austria in June 2008

This report contains the results of absolute gravity measurements carried out at the Conrad Observatorium in Austria in August 2007. 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 this experiment was to calibrate the superconducting gravimeter: the absolute gravimeter operated simultaneously side-by-side with the superconducting gravimeter on the same pillar for approximately 3,5 days. The comparison between the times series from both instruments allows us to determine the scale or calibration factor of the superconducting gravimeter. During the experiment, the absolute gravimeter Jilag-6 from the Federal Office of Metrology and Surveying (BEV) occupied a site on the same pillar.
