Abstract. To create an interference-proof navigation system based on the Earth’s gravity field, it is necessary to form a navigation gravimetric map. For remote and inac­cessible territories and water areas, for example, in the Arctic region, it is advisable to use onboard space measurement instruments. To date, a number of foreign projects have been implemented to measure the second gradient of the gravitational potential onboard a spacecraft. To form a navigational gravimetric map, it is necessary to transfer, reduce, the results of measurements to the Earth’s surface. The paper presents existing ap­proaches to performing the reduction. Own methods of reduction of measurement results are presented.

Keywords: space gravimetric means, navigation gravimetric map, reduction.
