Rudder roll stabilisation
High speed stability
Minimise roll motion
The Adaptive Steering and Stabilising Autopilot (ASSA) system is a control system which combines the control signals for course keeping and roll reduction.
Thereby the rudder and the steering gear accomplish two functions: steering and roll stabilization. Roll stabilization is achieved as the rudder applies a torque against the roll motion, using the same principle as a conventional fin stabilizer.
