ABSTRACT:
A heading indicator is disclosed which utilizes a one degree of freedom platform stabilized by a two degree of freedom dry flexure gyro. The output of one of the sensitive axis is coupled through an amplifier to the corresponding torquer in the gyro and selectively through an another amplifier to the opposite torquer. The other sensitive axis output is coupled through an amplifier to the platform. The indicator initializes at true north and is then switched to a directional gyro mode.
