Abstract
A gravity gradiometer including first and second proof masses and a device for providing simultaneous free flight of the proof masses under the influence of the gravitional force in which the gradient is to be measured and a capacitance device for monitoring the movement of the centers of mass with respect to each other during free flight by monitoring capacitance between portions of the two proof masses.
