Abstract : The paper is a reeport on gravimetric work completed in the Soviet Union from 1966 to 1969. This work was carried out in the following divisions: Fundamental gravity determinations; Gravity determinations at sea; Study of the gravity variations; Development of instruments and methods for determining the vertical gravity gradient and Tidal variations of gravity. Some general theoretical problems of absolute gravity determinations by the method of free fall were investigated. Studies of the influence of gravity acceleration with elevation and resistance of the medium proportional to the first and second powers of velocity of a falling body, on the results of measurements were conducted by asymmetric method of three stations, symmetric method of two stations and symmetric method of one station. The planning of the installation for absolute determination according to the symmetric method of one station has begun. A series of theoretical and experimental investigations on the perfection of marine gravimeters and estimation of their accuracy was carried out. Studies relating to secular variations of the gravitational force, measurements of the vertical gradient of gravity, and earth tides in the USSR during 1967-1970 are considered. (Author)
