    Abstract: A gravity gradiometer is disclosed which has a sensor in the form of bars (41 and 42) which are supported on mounting (5) which has a first mount section (10) and a second mount section (20). A first flexure web (33) pivotall couples the first and second mount sections about first axis. The second mount has first part (25), a second part (25) and a third part (27). The parts (25 and 26) are connected by second flexure web (37) and the parts (26 and 27) are connected by 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).

    Abstract: A gravity gradiometer is disclosed which has sensor masses in the forms of bars 41 and 43 arranged orthogonal to one 5 another and transducers for providing an output signal indicative of movement of the bars in response to changes in the gravity gradient tensor. The transducers are formed from thin film structure having a first layer forming a fine pitch coil 510 and a second layer forming a 10 coarse pitch coil 511. The layers are separated by an insulating layer. The coarse pitch coil 511 forms a transformer for stepping up the current flowing through the fine pitch coil 510 and the coarse pitch coil 511 supplies current to a SQUID device 367.

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.
