ABSTRACT:
A fluid sphere gyroscope is used as the north-seeking sensing element in a gyrocompass. A sensor responsive to angular deviation of the gyroscope from the horizontal provides a tilt signal which is used to energize heating elements located along the independent spin axis of a rotating fluid mass. Application of a thermal gradient along the spin axis of the fluid mass causes a controlled precession of the gyroscope, thereby compensating for bias and acceleration sensitive drift errors and precessing the gyroscope about a vertical axis in a controlled manner. Rotary transformers permit inductive coupling of the heating elements to the tilt signal and to a power source with minimal disturbing torques.
