ABSTRACT:
A vibration gyroscope with a mass mounted for vibrational movement on a central post. Sensing capacitors are mounted adjacent the mass for sensing vibrational movement in two perpendicular axes. The mass includes a pair of elements mounted between the parallel arms of an H shaped frame and powered for equal and opposite vibrations so that no movement is imparted to the frame except that caused by forces induced by rotational movement.
