What NMEA-sentences to use for a generic Rudder Only AP?

Postby Joerg Pauly » Wed 18 Apr 2012 - 20:24

Hello, everyone,

I'm using WGPS5Pro onboard on my notebook. What a great stuff...

Now I want to build my own AP, or should I better say: Rudder Controller.
I want to drive an electric starter engine with an ATMEGA64 micro controller, driven by my own software.

Well, here are my questions:

Does WGPS5Pro send NMEA sentences that tell an AP "Steer <direction> with <steer strength>"?
What sentence should I read out for that?

Or should I better calculate the rudder angle from the information COG, DTWP, next CTWP, last XTE, actual XTE?

I hope anyone can give me a hint.

Kind regards
Joerg Pauly
