The task of preparing navigation data bases for assisting navigation systems for the first and second derivatives of the gravitational potential is an actual one. In this paper, we analyze the possibility of using digital elevation maps to create databases of navigation data for acceleration of gravity and gravitational gradients.

Key words: Earth’s gravitational field, gravity acceleration, gravitational gradients, digital
terrain maps.
