Abstract : A previously developed gravity gradiometer was further developed to become a very sensitive gravitational gradiometer. A passive subtraction of the thermal sensitivity can be accomplished at low frequencies. This subtraction can be extended to higher frequencies by coupling the temperature sensing coil more tightly in temperature to the gradient sensing coil. This could be accomplished by mounting the temperature sensing coil to the inside surface of the gradient sensing coil form. Keywords: Superconducting Accelorometer; Gravity Gradiometer.
