Using the 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.
To achieve this, the GPS or the navigation software must feed the system with the
following NMEA sentences:
- $xxXTE : cross-track error and
- $xxBWC : bearing and distance to waypoint (DTW and BTW) or
- $xxRMB : XTE, latitude, longitude and bearing and distance to waypoint (DTW and
BTW as minimum data).

WARNING:
Make sure your position is as close as possible to the route before engaging the pilot.
When Cross-track Error is greater than 0.4 nm, the Gyropilot will apply a 45° angle to
the route bearing.
When reaching the WAYPOINT the pilot triggers an audible alarm, keeps the
compass heading and quits the GPS mode. The skipper must check that the route is
safe and that the bearing to the next WAYPOINT is correct before pressing AUTO to
resume the GPS mode. This has to be repeated for every WAYPOINT.
WARNING:
Your GPS or navigation software which is connected to the pilot may be able to
activate the next waypoint automatically. In that case the pilot will follow the route's
legs accordingly.
