GHP 10 Installation Instructions 21
Category Setting Description
Rudder Gains High Speed
Gain
Allows you to set the rudder
gain for high speeds.
This setting applies to the
vessel when operating above
planing speed.
If you set this value too
high, the autopilot may be
overactive, attempting to
constantly adjust the heading
at the slightest deviation.
An overactive autopilot can
cause excess wear and tear
on the drive unit ( page 17 ).
Rudder Gains High Speed
Counter
Allows you to set the rudder
gain counter-correction for
high speeds.
This setting applies to the
vessel when operating above
planing speed.
If you set this value too
high, the autopilot may be
overactive, attempting to
constantly adjust the heading
at the slightest deviation.
An overactive autopilot can
cause excess wear and tear
on the drive unit ( page 17 ).
NMEA Setup NMEA
Checksum
If the connected NMEA
0183 GPS unit incorrectly
calculates checksums, you
may still be able to use it
if you turn this setting off.
When set to off, data integrity
is compromised.
NMEA Setup Reversed XTE If the connected NMEA 0183
GPS unit sends the incorrect
steering direction with the
cross track error signal. You
can use this setting to correct
the steering direction.
Navigation Setup Navigation
Gain
Allows you to adjust how
aggressively the autopilot
eliminates cross-track error
while following a Route-To
pattern.
If this value is too high, the
autopilot can oscillate back
and forth across the course
line over long distances.
If this value is too low, the
autopilot may respond slowly
in eliminating cross-track
error.
Navigation Setup Navigation
Trim Gain
Allows you to adjust the
acceptable amount of long
term cross-track error while
following a Route-To pattern.
Only adjust this setting after
the navigation gain has been
set.
If this value is too high, the
autopilot will overcompensate
for cross-track error.
If this value is too low, the
autopilot will allow a large
long term cross-track error.
Category Setting Description
Steering System
Setup
Verify Steering
Direction
This setting tells the autopilot
which direction the rudder
must move to turn the vessel
to port and to starboard.
You can test and reverse
the steering direction if
necessary.
Steering System
Setup
Lock-to-Lock
Turns
Allows you to adjust the
number of turns it takes
your helm to go from lock to
lock (fully turned port to fully
turned starboard).
Steering System
Setup
Helm
Displacement
Allows you to calibrate helm
displacement.
Steering System
Setup
Linkage
Compensation
Allows you to adjust the
linkage compensation if the
steering is loose or sloppy.
The higher you set this
value, the more the autopilot
compensates for loose or
sloppy steering. Use this
setting with caution.
NOTE: Advanced configuration settings are available when using
the advanced configuration procedure ( page 17 ). Other settings are
available during normal operation of the GHP 10. See the configuration
section of the GHC 10 Owner’s Manual for more information.
