We solve the problem of construction of the dipole model best describing (in the sense of least squares) the global geomagnetic field on measurement data. In contrast to known setting up this problem the geomagnetic field modulus but not the vertical component is considered as initial measurements. This enables us to use the method for redicing data derived from the board of non-stabilized satellites. As an illustration of the method potentialities the dipole model we constructed with the use of «measurements» simulated by the IAF-85 (International Analytical Field) model and an accuracy estimation is presented.
