| Abstract: | For a special use a new modelling method of evaluating external disturbing potential is presented in this paper. Being different from classical methods in physical geodesy this method is grounded upon the theory of unified representation of gravitational field. The models created in this way are particularly suitable for a high speed computation of gravitatioal field in low altitude because they take account of topographic effects and have their kernel functions with simple structure and weak singularity. |
