Abstract
Gyrocompass heading step-by-step repeater amplifier channels are provided with protection from damage by accidental short-circuits occurring in one or more compass step-by-step data repeaters or in the cables extending to such repeaters. Total shut-down of the affected channel or channels is effected by fast-acting thyristor pulse control circuits and the channels are automatically reset when the fault is removed. A cooperative latching short-circuit alarm is provided.
