A common way to localize a magnetic target is to look at the maximum of the magnitude of the magneticeld gradient. In this thesis, we consider a threeaxis total eld gradiometer which measures the gradient of the magnitude of the magnetic eld along three orthogonal axes. Based on the measured data from the three-axis total eld gradiometer, we decompose the inversion problem into two linear systems. By solving those two systems, we get an approximation for the location and moment that we are looking for. For the considered gradiometer, we can improve the parameters if the detailed geometry of the gradiometer is taken into account.
