FIELD: physics.
SUBSTANCE: static gravity metre comprises a functionally connected sensitive system having an elastic member and a connected weight, a sensor for detecting small displacements of the weight from the initial (zero) position, a device for bringing the weight into the initial (zero) position, a computer and a recorder. The invention is characterised by that the static gravity metre is fitted with a sensor for the length of the elastic member and or change thereof, the output of which is connected to the input of the computer.
EFFECT: high accuracy of determining gravity at sea.
