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: A gravity gradiometer is disclosed which has a pair of sensor bars 41, 42 mounted in housings 43 and 45. 5 Transducers 71 are located adjacent the bars for measuring movement of the bars in response to the gravity gradient tensor. Signals from the transducers are supplied to a SQUID device 367 for processing the signals. A connector is supplied for connecting the circuitry to external 10 equipment which comprises a container 560 having a feed through filter 564, a three terminal cap 565, a relay 566 and an output terminal. The output terminal is connected to further RF attenuation which comprises a second connector 5b having parallel inductors and resistors.

Abstract: Disclosed is a gravity gradiometer for measuring components of a gravitational gradient tensor. The gradiometer comprises a sensor (40) for measuring the components of the gradient tensor and a mounting for supporting the sensor. The mounting comprises; a first mount, a second mount, and connectors. The first mount (10) has a base, a cylindrical hub protruding from the base, a peripheral wall (14) disposed around and spaced from the hub and provided with a plurality of circumferentially spaced cutouts (16), and a central core coaxial with the hub and attached to the hub by a first flexure web to provide for relative rotation between the core and base about a first axis. The second mount fits within the peripheral wall of the first mount and has first, second and third parts. The first and second parts connect via a second flexure web for relative rotation about a second axis orthogonal to the first axis. The second and third parts connect by a third flexure web for relative rotation about a third axis orthogonal to the first and second axes. The connectors (13) extend outwardly from the first part of the second mount through the cutouts in the peripheral wall of the first mount for connecting the mounting to an external platform. The third part of the second mount is attached to the core of the first mount and the sensor is connected to the base of the first mount. Hence the sensor is rotatable with the base of the first mount about all three orthogonal axes.

Abstract: Disclosed is a system for measuring a gravity gradient tensor. The system comprises of: a gravity gradient sensor (40) with a pair of transversely arranged masses (41, 42) for use in a gravity gradiometer for measuring components of a gravity gradient tensor; a calibration sensor for sensing, at room temperature prior to cryogenic operation of the gravity gradiometer, whether one of the pair of masses associated with the calibration sensor is balanced; and an adjusting mechanism for adjusting the balance of the masses at room temperature prior to cryogenic operation of the gravity gradiometer. The calibration sensor comprises a resonant circuit having an inductor, and a capacitor which has a first plate formed by a surface of one of the masses and a second plate spaced from that surface of one of the masses; and an oscillator for receiving a signal from the resonant circuit and for producing an output signal indicative of the spacing between the first plate and the second plate. In use the calibration sensor produces a signal indicative of the balance of the one of the pair of masses associated with the calibration sensor.
