Study to Develop Gradiometer Techniques.

Abstract

The primary goal of the gravity gradiometer research effort at Stanford University has been to establish the feasibility of operation of a gravity gradiometer in a closed loop mode. A parameter estimation technique will allow for on-line modification (compensation) of the sensor output signal, as well as for trimming of pertinent sensor physical properties so as to improve instrument performance. Gravity gradiometers are required to operate with an accuracy of 1 EU (Eotvos unit). This is so demanding that closed loop mode operation may be essential. Although attention has been focussed exclusively upon the Hughes rotating gravity gradiometer (RGG), the parameter estimation method developed is applicable, in principle, to any instrument subject to dynamically induced errors.
