Title: | Intercomparison of IMGC Absolute and GWR SuperConducting Gravimeters | Issue Date: | 1995 | ISBN: | 3-540-59204-0 | Keywords: | Gravity Gravitation Earth Tides Gravimeters |
Subject Classification: | 04. Solid Earth::04.02. Exploration geophysics::04.02.02. Gravity methods | Abstract: | In May 1994 a first comparison campaign between a superconducting and the IMGC absolute gravimeter has been performed in Brasimone, near Bologna in Italy. The superconducting gravimeter was previously calibrated by means of a moving ring, the mass of which has been measured with the highest accuracy allowed by the actual technology. During the three days of observation with the absolute gravity meter, a maximum, a complete semidiurnal curve and a minimum of the tidal effect has been observed. These data have been used to compute the calibration factor of the superconducting gravity meter; it agrees in a rather satisfactory way with the results of the calibration with the moving mass. |
