Fig. 13From: Experimental study on improving the accuracy of marine gravimetry by combining moving-base gravimeters with GNSS antenna arrayFourier time–frequency analysis of Eötvös corrections. a and c are the single-sided amplitude spectra of the Eötvös corrections of S1-1 and X1-1, respectively; the small windows are enlarged views of the low-frequency band. b and d are the corresponding time-domain Eötvös correctionsBack to article page
