ABSTRACT:
The method and apparatus in one embodiment may have: a gyro housing containing a bias field; a bias field that generates a stable axial magnetic field; Xenon or other gas contained within at least a portion of the axial magnetic field, Xenon or other gas nuclear spins precessing at a constant angular rate with respect to the gyro housing in response to the axial magnetic field; wherein reversing a polarity of the bias field reverses a polarity of the magnetic field and a polarity of the precession of the Xenon or other gas nuclear spin, and wherein a reversing of the polarity of the gyro scalefactor thereby results without reversing a polarity of the gyro bias.
