Direct it:We will try to correct the axis to the West every time the axis is tilted upwards and East every time the axis is tilted downwards.
This way we create a flat ellipse.
DIRECTIVE SYSTEM
Hermann Anschütz-Kaempfe (1907- Germany)
Bottom heavy Top heavy
Elmer Amborse Sperry (1911- USA)
spinning clockwise spinning anti clockwise
piece of weight underneath the spinning gyro housing
will try to reduce the existing angle of the axis
piece of weight on top of the spinning gyro housing
will try to increase the existing angle of the axis

Horizontal damping in order to counter effect thedirective precession.
(damping ring on top of housing)
Vertical damping with precession opposite to heeling of housing.
(weight on Westside of housing)
