ABSTRACT:
The invention is directed to a measurement of rotation of a body with respect to a fixed inertial coordinate system by use of an oscillator that is rotationally symmetrical about one axis, a locking oscillator for injecting locking the rotationally symmetric oscillator to a selected frequency and state of polarization and measuring the polarized orientation of the oscillator with a polarization detector.
