Gyro slaving/boot strap amplifier

A gyro slaving/boot strap amplifier for driving a heading indicator and a remote magnetic instrument, comprising in combination:

• switching means receiving input signals from the headng indicator and magnetic position data from a flux detector to provide a heading error signal and an angular position signal,
• a timer generating a time sharing signal to said switching means to alternate the operation thereof between providing the heading error signal and the angular position signal,
• a slaving circuit responsive to the heading error signal from said switching means to provide a correction voltage to the heading indicator, and
• a modulator/demodulator responsive to the angular position signal from said switching means and a modulation signal from the remote magnetic instrument to provide an energizing signal thereto.

A gyro slaving/boot strap amplifier for driving a heading indicator having a control transformer with a rotor and stator, and further driving a remote magnetic instrument, comprising in combination:

• a time sharing switch receiving a heading error signal as generated at the rotor of the control transformer, magnetic position data from a flux detector, and an angular position signal from the stator of the control transformer,
• a timer generating a time sharing signal to said switch to alternate the operation thereof to:
• first, apply the magnetic position data to the stator and the heading error signal to an output of said time sharing switch, and second, applying an excitation signal to the rotor and the angular position signal to the output of said time sharing switch,
• a slaving circuit responsive to the heading error signal from said time sharing switch to provide a drive voltage to the heading indicator, and
• a boot strap circuit responsive to the angular position signal from said time sharing switch to provide an energizing voltage to the remote magnetic instrument.
