In airborne gravimetry the data received from an airborne survey system is used to construct maps of gravity anomaly and to calculate their transformations, such as the anomalous gravity at the geoid surface, the disturbing potential, the plumb-line deflections etc. Most of the above are the inverse ill-posed problems. Thereby the quality of the maps depends largely on the methods of transformations. The paper discusses application of the spherical wavelet expansion technique and proposes an algorithm of transformation which is almost free from the method errors.

Keywords: gravimetry, gravity disturbance, wavelets.
