Abstract : The concept and operating characteristics of a radially vibrating gravitational gradient sensor are presented. The sensor is a tuned mechanical oscillator that responds to gravity-gradient forces when it is rotated in a stationary gravitational field. Because of the inherent dynamic magnification resulting from resonant or near resonant operation of the sensor it obtains high sensitivity and can potentially be used as an accurate attitude control sensor, an orbital altimeter, or a navigation aid in a variety of satellite applications.
