The International Comparison of Absolute Gravimeters is only way to determine the level of the accuracy of such measurement instruments currently in use in gravimetry. The calibrations of the frequency of the laser radiation used in the laser interferometer of the absolute ballistic gravimeter (ABG) and of the frequency of the Rb-clock used as the reference for the time interval measurement systems of ABG are necessary but insufficient to perform a complete calibration of ABG as the measurement standard of the unit of the derived physical quantity acceleration.

Abstract
The International Comparison of Absolute Gravimeters is only way to determine the level of the accuracy of such measurement instruments currently in use in gravimetry. The calibrations of the frequency of the laser radiation used in the laser interferometer of the absolute ballistic gravimeter (ABG) and of the frequency of the Rb-clock used as the reference for the time interval measurement systems of ABG are necessary but insufficient to perform a complete calibration of ABG as the measurement standard of the unit of the derived physical quantity acceleration.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
