ABSTRACT:
In order to eliminate the day-to-day gyro drift phenomena which result from interaction of the magnetic pole position of the synchronous motor typically used to drive the gyro and the gyro wheel, an induction motor controlled by a phase locked loop referenced to an appropriate control frequency is utilized to drive the gyro.
