Abstract: La figura muestra un gradiometro de gravedad que tiene un sensor en forma de barras (41 y 42) afirmadas en un montaje (5) que tiene una primera seccion de montaje (10) y una segunda seccion de montaje (20). Un primer pliegue de refuerzo (33) se acopla girando la primera y segunda seccion de montaje en torno al primer eje. El segundo montaje tiene una primera parte (25), una segunda parte (26) y una tercera parte (27). Las partes (25 y 26) están conectadas mediante un segundo pliegue de refuerzo (27) y las partes (26 y 27) están conectadas con un tercer pliegue de refuerzo (25). Las barras (41 y 42) están colocadas en casetas (45 y 47) y forman una estructura monolítica con las casetas (45 y 47) respectivamente. Las casetas (45 y 47) están conectadas con los lados opuestos de la segunda seccion de montaje (20). Las barras (41 y 42) están conectadas con sus respectivas casetas mediante los pliegues de refuerzo (59). Los transductores (71) están colocados cerca de las barras para detectar movimientos en las barras para, a su vez, permitir medir el tensor del gradiente gravitacional. La primera seccion de montaje (10) tiene recortes (16) y la segunda seccion de montaje (20) tiene lengüetas (13) que pasan a través de los recortes para conectar la primera y segunda seccion de montaje (10 y 20) en un recipiente Dewar (1).

Abstract: A heat switch 570 is disclosed as well an a gradiometer having the heat switch. The heat switch is formed from a non-magnetic material such as a semi-conducting material. The semi-conducting material may be provided by way of a Hall effect device. The heat switches are arranged in the gradiometer on a circuit board 856. The circuit board 850 has conducting strips 856 which are connected to conducting strips on a sensor 71 by bridges 852. The heat switch 570 is connected on the opposite side of the circuit board 850 to the strips 856 and processing circuitry 859. A copper substrate 865 is provided on the same side of the circuit board as the heat switch 570 to conduct heat away from the heat switch 570 when the heat switch is closed.

Abstract: A gravity gradiometer and method for forming a pivot flexure web for a gradiometer is disclosed. The gradiometer has measurement bars 41, 43 supported in housings 45 and 47 and transducers 71 for measuring movement of the bars to provide an indication of the gravity gradient tensor. The bars 41, 43 are mounted on flexure webs. The webs are formed in separate elements to the housing and bars.

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.
