摘要： An airborne gravity-based transducer is disclosed as two embodiments with similar physical structures but different operating principles. The first design includes a particle acting as an active interface characterized by internal vibrations relating to its de Broglie wave, a resonant cavity for trapping the particle, and a phonon-wave source wherein the de Broglie and phonon waves interact over a junction area. In the second design, mechanical displacements between the transducer elements can be monitored through electromechanical transduction. Both designs include a power source and a biasing circuit for producing an electrical current across the junction, and a sensing system for measuring voltage. Both designs are capable of cancelling slowly-varying gravitational acceleration due to dynamic interaction in motion with the gravitational field and responding to small-scale gravity anomalies. The transducer can be utilized in hydrocarbon exploration to provide information on areas conducive to fluid entrapment in the sedimentary column.

摘要： A method for calculating performance of satellite gravity field measurement by low-to-low satellite-to-satellite tracking, includes: acquiring parameters of gravity satellite system; calculating an effect of satellite loads on the power spectrum of nonspherical perturbation potential, so as to obtain an degree error variance; comparing degree error variance with degree variance given by Kaula Rule, and when degree error variance equals degree variance, considering that the highest degree of gravity field measurement is obtained, calculating geoid degree error and its accumulative error, gravity anomaly degree error and its accumulative error, so as to obtain the performance of satellite gravity field measurement by low-to-low satellite-to-satellite tracking. The method is capable of evaluating gravity field measurement performance quickly and effectively, obtaining a rule of effects of the gravity satellite system parameters on the gravity field measurement performance, so as to avoid shortcoming caused by numerical simulation.

摘要： A non-contacting spherical air bearing-based stable platform for use by a gravity gradiometer instrument (GGI) is provided by attaching a spherical ball-shaped bearing to a rotational stage of the GGI and integrating a concave spherical cup in the linear stage and mounting base assembly of the GGI which is fixedly attached to a host vehicle or platform. The spherical cup supports the spherical ball-shaped bearing on a thin cushion of air provided by a source of compressed air or gas at the concave surface of the spherical cup. The spherical ball-shaped bearing is supported, providing three degrees of rotational freedom of motion without the need for slip rings, flex capsules, races, or mechanical bearings, thereby reducing or eliminating gradient disturbance signals owing to parasitic torques and jitter in the output of the accelerometers of the GGI.

摘要： A gravimeter for measuring the gravitational field of the Earth without an inertial reference comprises accelerometer pairs disposed on a platform where the sensitive axis of each accelerometer is arranged on the platform to measure plumb gravity. At least one accelerometer pair is spatially configured to define a baseline therebetween. The gravimeter is positioned so that the baseline is maintained parallel to a linear survey path. Each accelerometer outputs a signal representative of the sum total of the accelerations detected, including accelerations due to gravity and kinematic accelerations of the host vehicle and mounting structure. A processor subtracts the accelerometer pair outputs for common-mode rejection determination of a down gravity gradient and combines with a direct plumb gravity measurement to obtain an enhanced gravity data output that is not subject to frequency limits attributed to the performance limitations of inertial reference devices.

摘要： A gravity gradiometer having at least three differential accelerometers with a low response to linear accelerations and at least six angular accelerometers that give it the capability of measuring angular rates by integrating the angular accelerations. Both types of accelerometers are based on a compliant mechanism with very low and adjustable stiffness that is achieved by using flexures under compressive load that contribute a negative stiffness to the total elastic response of the mechanism. Both types of accelerometers are operated in a servo-compensation feedback mode so that at no time is the mechanism far from its equilibrium position.
