摘要：A gravity gradiometer having at least three differential accelerometers with alow response to linear accelerations and at least six angular accelerometers that give itthe capability of measuring angular rates by integrating the angular accelerations. Bothtypes of accelerometers are based on a compliant mechanism with very low and
adjustable stiffness that is achieved by using flexures under compressive load thatcontribute a negative stiffness to the total elastic response of the mechanism. Both typesof accelerometers are operated in a servo-compensation feedback mode so that at notime is the mechanism far from its equilibrium position.
