摘要：
Two methods of utilizing data from magnetic satellites for the secular variation modelling are proposed. Both methods are based on the parametric expansion in time, where natural orthogonal components are used as parameters. As data for such expansion are used time series of coefficients of spherical harmonic models, developed from satellite data for each day.
