Study to Develop Gradiometer Compensation Techniques.

Abstract

The primary goal of the gravity gradiometer (GG) research effort at Stanfrod University has been to establish the feasibility of operation of a GG in a closed loop mode. A parameter estimation technique will allow for online modification (compensation) of the sensor output signal as well as fro trimming of pertinent sensor physical properties so as to improve instrument performance. Gravity gradiometers are required to operate with an accuracy of E.U. This is so demanding that closed loop mode operation may be essential. Although attention has been focused 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.
