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 another amplifier to the opposite torquer. The other sensitive axis output is coupled through an amplifier to the platform. The indicator initializes to true north and is then switched to a directional gyro mode.
