GPS mode
In
GPS
mode, the
GyroPilot 3
steers the boat by following the route given by the GPS. To
do this, a GPS or other instrument that delivers NMEA GPS sentences must be connected to
an NMEA input on your installation.

A graph shows the cross track error, the XTE.

(Course Over Ground in °),

(Distance to
Waypoint in Km or M),

in Km or NM
information is displayed.
The GyroPilot 3 processor follows the route to the Waypoint. On arrival at WAYPOINT <
0.1NM, the NKE displays beep and the autopilot switches to compass mode. If the user
enters a new waypoint, the GyroPilot 3 automatically switches back to GPS mode.

Polar mode
The polar mode enables the boat to follow an optimal wind angle. This angle is the best
upwind angle when heading into the wind: VMG up, or the best angle when heading down
the wing in downwind conditions: VMG down. Apart from the set-point change in relation to
the wind speed, this mode functions like a true wind mode.

THE SUPER MODES
The SUPER modes are used in addition to the main modes. They allow the autopilot's set
point to be adjusted slightly in response to a temporary phenomenon: heel variation, gust
In the GyroPilot 3, only one SUPER mode can be activated at one time. There are 3 states in
a SUPER mode:
•
Status: OFF.
The skipper has not selected SUPER mode.
•
Status: Standby.
SUPER mode is ready to be used, but it is not active yet:
o
a piece of data is missing,
o
the autopilot is not activated,
