Pilot Settings - NKE Multigraphic User Manual & Installation Sheet

Autopilot in GPS mode
In GPS mode the Gyropilot steers the boat to a route provided by the GPS or the
navigation software connected to the NMEA input of your Topline system.

2.5.4 Pilot settings

Select the pilot's settings page:
Rudder coefficient
Principle: the Gyropilot processor automatically adjusts the value of the rudder
angle to apply which is proportionally opposite to the boat speed. The faster the boat
sails the lower the rudder angle.
This can be tuned to achieve best results by modifying the rudder coefficient between
the 1 and 53 value range. The higher the value is, the greater the rudder angle
proportionally to boat speed. The default setting is 6, which is valid for a 30 footer.
Examples: a Figaro 2 or similar boat will require this factor to be 15, for a 60 footer it
can be 20 and a multihull will be better with 30.
Note: if there is no boat speed data on the Topline bus, the Gyropilot uses SOG
(Speed Over Ground) if available.
A good way to learn the effect of this value setting is to enter an extreme
value, i.e. 50, and note the different behaviour of the boat before and after
the setting change.
