Rudder roll stabilisation

High speed stability

Roll motion control

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.
