摘要

Lithuanian gravitational field researches have been conducting since 2016. The aim is to increasethe accuracy of the geoid, as well as the accuracy of the normal heights determined by the methods ofspace geodesy. It is important to have high accuracy and dense data when simulating the field of gravityin the terrain. In order to simulate the field of gravity in the territory of Lithuania, it is necessary to include areas of lakes. The data obtained can also be used for geophysical and geodynamic studies and forprecise navigation.The methodology and technology of the gravity survey of Lithuanian territory are presented. Thestress on quality parameters of the gravity survey is done.According to the project, the standard deviation of the measured gravity at the gravity surveypoints should not be more than 60 μGal, and the standard deviation of Bouguer anomalies should be better than 80 μGal. The average distance between gravity points should be about 1.5 – 2 km.
