ABSTRACT:
A self-contained gyrocompassing system providing switch means with coarse align and gyrocompass modes of operation. Starting in the coarse align mode, a north bubble sensor output along with an initial vertical error signal output is applied to an east torquer which coarsely levels the east gimbal. Subsequently, the switch means is placed in the gyrocompass mode and the signal from the north sensor is simultaneously applied to the east gyro and the azimuth gyro loops. A voltage threshold detector determines whether the signal from the north sensor requires low or high rate azimuth torquing. If high rate azimuth torquing is required in the azimuth gyro loop, the east gyro loop is either locked or torqued at a high rate.
