Results of the International Comparison of Absolute Gravimeters in Walferdange (Luxembourg) of November 2003

The results of an international comparison of absolute gravimeters held in Walferdange Luxembourg in November 2003 are presented. The absolute meters agreed with one another with a standard deviation of less than 2 µGal (1 Gal = 1 cm/s2) (if we exclude one prototype instrument from the analysis). For the first time, the ability of the operators was put to the test. The comparison indicates that the errors due to the operator are less than 1 µGal, i.e. within the observational errors.
