Description
We report the uncertainty evaluation of the atomic gravimeter KRISS-AGRb-1 developed at KRISS with the total uncertainty of below 30 nm/s^2 which is mainly limited by a wavefront distortion, and we present the way to overcome the uncertainty limited by the wavefront distortion and reach the accuracy of below 10 nm/s^2, by combining adjusting beam size of a detection laser and compensating the bias by the direct measurement of the wavefront distortions induced by all optical elements
