    Abstract: A gravity gradiometer is disclosed which has a sensor in the form of bars (41 and 42) which are supported on a mounting (5) which has a first mount section (10) and a second mount section (20). A first flexure web (33) pivotally couples the first and second mount sections about a first axis. The second mount has a first part (25), a second part (26) and a third part (27). The parts (25 and 26) are connected by a second flexure web (37) and the parts (26 and 27) are connected by a third flexure web (35). The bars (41 and 42) are located in housings (45 and 47) and form a monolithic structure with the housings (45 and 47) respectively. The housings (45 and 47) are connected to opposite sides of the second mount section 20. The bars (41 and 42) are connected to their respective housings by flexure webs (59). Transducers (71) are located in proximity to the bars for detecting movement of the bars to in turn enable the gravitational gradient tensor to be measured.

    Abstract: La presente descripción proporciona un gradiómetro de gravedad que comprende un componente que comprende un detector para generar una señal en respuesta a un cambio en el gradiente de gravedad experimentado mediante el gradiómetro de gravedad. El gradiómetro de gravedad también comprende una estructura de soporte para soportar el componente en una forma para que el componente se pueda mover con relación a la estructura de soporte. Además, el gradiómetro de gravedad comprende un sensor de aceleración para percibir una aceleración asociada con una aceleración externa cuando el gradiómetro de gravedad se expone a la aceleración externa. Además, el gradiómetro de gravedad comprende un accionador para generar una fuerza en el componente como una función de una aceleración percibida mediante el sensor de aceleración y un parámetro de respuesta asociado con el componente. El accionador se dispone para aplicar una fuerza generada para que se reduzca la transmisión de la aceleración desde la estructura de soporte hacia el componente.

    Abstract: The present disclosure provides a gravity gradiometer for detecting a gravity gradient. The gravity gradiometer comprises at least two sensor masses that are pivotable about respective axes and each experience a change in torque in response to a change in gravity gradient whereby the at least two sensor masses move relative to each other in response to the change in gravity gradient and wherein a signal indicative of the gravity gradient is generated in response to the relative movement of the at least two sensor masses. Further, the gravity gradiometer comprises an acceleration sensor for sensing an acceleration associated with an external acceleration applied to the gravity gradiometer. The gravity gradiometer also comprises an actuator for generating an adjustment force that is dependent on an acceleration sensed by the acceleration sensor. The adjustment force is also dependent on a mechanical response parameter associated with at least one of the at least two sensor masses. The adjustment force is applied such that a difference between the magnitudes of the torques experienced by the at least two sensor masses in response to the change in gravity gradient is reduced.

    Abstract: Se describe un gradiometro de gravedad que tiene un sensor en la forma de barras (41 y 42) que van apoyadas en un soporte (5) que consta de una primera seccion de soporte (10) y una segunda seccion de soporte (20). Una primera banda continua flexional (33) acopla sobre un eje la primera y segunda secciones de soporte alrededor de un primer eje. El segundo soporte tiene una primera parte (25), una segunda parte (26) y una tercera parte (27). Las partes (25 y 26) van conectadas por una segunda banda continua flexional (37) y las partes (26 y 27) van conectadas por una tercera banda continua flexional (35). Las barras (41 y 42) estan localizadas en carcasas (45 y 47) y forman una estructura monolitica con las carcasas (45 y 47), respectivamente. Las carcasas (45 y 47) van conectadas a lados opuestos de la segunda seccion de soporte (20). Las barras (41 y 42) van conectadas a sus respectivas carcasas por bandas continuas flexionales (59).
