Abstract

A new gravity-measuring system is capable of resolving gravitational acceleration with a sensitivity sufficient to distinguish the effect of one-foot vertical displacement on the earth's surface (0.1 milligal). Developed by Textron's Bell Aerosystems Company, the Motion Stabilized Gravity Measuring System (BGM-2) is built around a standard accelerometer and coupled with a small Varian computer (620/i) that separates wave motion from the changes in gravity while permitting simultaneous collection of other data. The computer integrates the following inputs into a common data storage block: the reduced gravity readings, magnetometer readings, depth soundings, navigational information, and pulse rates from a crystal oscillator.
