1.5.5 Operation in GPS mode
In
GPS
mode, the
Gyropilot
steers the boat according to a
course
provided by the GPS. For
that, a GPS or any other instrument providing GPS NMEA frames must be connected to the
NMEA input of your
Topline
installation and we must have a active course. The GPS
configured in navigation mode will need to provide the NMEA frames below (see NMEA
initialisation chapter):
-
$xxXTE
: cross-track error
-
$xxRMB
: XTE, latitude, longitude and distance and heading to destination (DTW and BTW
in minimal data).
-
$xxBWC
: distance and heading to destination (DTW and BTW)
The
GPS
mode
screen below is displayed:
-
A graph
allows to view the cross-track error, i.e. the XTE.
-
The information on
CTW
(Heading towards WayPoint),
COG
(bottom heading in °),
DTW
(distance to WayPoint in Km or Mn),
SOG
(bottom speed in Km/hr or Kt) and
XTE
are
displayed.
At the engine, the orientation of the boat and its distance in relation to the course are not
important. When pressing the AUTO key, the boat rejoins the course, turning round if
necessary. If the cross-track error is too significant (> 0.4 Nautical miles), the boat rejoins the
course at a 45°angle.
When the WAYPOINT is reached, the pilot sounds, it maintains the compass heading and exits
the GPS mode. The skipper must then check that his course is clear and that the direction to
the next WAYPOINT is correct. He then presses the AUTO key once more: this will enable the
GPS mode once again, directing the boat towards the next WAYPOINT. The procedure is
repeated for each new WAYPOINT.
