Abstract
A frequency readout gyroscope is provided, having 2 or 3 axes, in which the frequency of the carrier associated with the oscillation of the proof mass changes while the amplitude stays constant. The invention departs from conventional gyroscopes which rely on measuring transducer sense axis displacement (amplitude modulation) to determine angular input rate. The invention utilizes what could be termed a form of frequency modulation, such as evaluating frequency phase difference between the axes of modulation. Examples include gyroscopes having either a quadrature or Lissajous FM mode of operation, in which angle random walk contribution from the electronics is reduced by approximately two orders of magnitude.
