Determination of Beam-position Dependent Transfer Functions for Tidal Recording LCR Gravimeters

Summary Authors propose a method for the determination of transfer characteristics and fine calibration of LCR relative gravimeters without feedback system used for earth-tide recordings, by means of the moving-mass gravimeter calibration device of Budapest-Mátyáshegy Gravity and Geodynamical Observatory. Beam-position dependent transfer functions of two relative LCR G type gravimeters were determined and analyzed and a new anisotropic correction of long-time recordings was introduced based on the anisotropic transfer characteristics.
