We suggest new high-technology algorithms based on the fractal approach to approximation of gravity and magnetic fields by equivalent sources located on different depths. The distribution of sources in space is determined by methods of constructing of quadrotree or multiresolution wavelet analysis. Results of computing experiments are given in this paper.
