Abstract
The analysis of the definition of a measurement standard in metrology applied to the field of gravimetry shows that both gravity networks and absolute ballistic gravimeters can be the measurement standards in gravimetry, i.e., the standards of the acceleration unit in the measurement of free-fall acceleration. Currently, the absolute ballistic method is recognized as the primary reference method for the measurement of free-fall acceleration. As the measurement standard of acceleration, a derived physical quantity, the ballistic gravimeter should be traceable to the measurement standards of length and time (frequency) units. The accuracy level of absolute ballistic gravimeters may be determined by comparing the results of their measurements organized at sites where several gravimeters can perform measurements simultaneously according to a specified technical protocol.
