Electronic Control Module
The Electronic Control Module (ECM) monitors all the system sensors and automaticallyregulates operation of the Seakeeper.
The controller commands the motor speed and regulates the Seakeeper’s precession rate and angular position. This is accomplished by commands to a high response flow control valve in the hydraulic brake circuit that increases or decreases the precession rate.
