The six-degrees-of-freedom hydraulic motion system can provide the crew with realistic linear accelerations and rotation rates. For maximum power and precision, the symmetric actuators use hydrostatic bearings and are controlled by an advanced control system.
The six-degrees-of-freedom motion system is controlled by a multi-variable control system. The linear actuators are equipped with hydrostatic bearings and allow a 1.25 m stroke with advanced safety buffers. Robust actuator controllers compensate for internal variations in load, temperature, valve dynamics and other effects. The motion system can realize a maximum heave acceleration of 1.5 g and a minimum which lies below the threshold for human perception.
