Development of Electronic Control of a Superconducting Gravity Gradiometer.

Abstract

The design and assembly of the breadboard feedback circuit for the new NASA superconducting gravity gradiometer is completed. The circuit applies three kinds of feedbacks to the gradiometer instrument: (1) high frequency rejection, (2) cold camping, and (3) force rebalance. The primary purpose of these feedbacks is to increase the dynamic range of the instrument. The circuit has been tested at room temperature and is awaiting a test in connection with the actual gradiometer. Keywords: Gravity gradiometer; Gravity survey; Inertial navigation.
