GRAVIMETRY - REPORT ON SCIENTIFIC ACTIVITY IN GEODESY AND GRAVIMETRY IN 1963-1966.
Abstract
The development, manufacture and investigation, both under laboratory and field conditions, have been completed for an automatized vacuum pendulum apparatus necessary for high-precision relatiive determinations of gravity. The apparatus has thermostatic control; the pressure inside the apparatus is kept close to 1 mm of mercury column. The pendulums are quartz-metal with temperature compensation. The operation of the apparatus is completely automatized and carried out by remote control according to a given program. Periods and amplitudes of pendulum oscillations are recorded by photoelectronic method and are computed from a conversion table. The virtual accuracy of determinations of the gravity increment between two points, performed according to the A-B-A program, is close to plus or minus 0.10 mgal /7, 43, 45/. (Author)
