Programming the GPS unit
This is the part of the GPS-to-Autopilot connection that causes the majority
of problems. If you have difficulty with the
GPS connection, please read
the relevant sections of your GPS manual carefully. The Bosun autopilot
looks for NMEA 0183 format data containing APA or APB or both XTE
and BOD information. For more information on this, see the Operations
section of this manual and consult your GPS unit manual
