A method of inverse gravimetric problem is reviewed – one that is based on regular rectangular grid density and field models. The research is based on a numerical implementation that is included in geological-analytical GIS INTEGRO. In the article some of the shortcomings of the method are pointed out, their causes and correction methods are discussed. A new algorithm based on the method is proposed, its conditioning is analyzed and a regularization method is suggested. The improved implementation is included in GIS INTEGRO.
