I am interested in using the ArduPilot on an autonomous surface marine vehicle to control the rudder. The vehicle control system is predicated on having the vehicle's bow (front) pointed in a steady direction; not on having the vehicle make a specific course over the ground. The vehicle has a flux-gate electronic magnetic compass that provides NMEA data on heading. What would be required to modify the code to replace the GPS heading with heading from the compass?Thanks
Sure, that's very possible. It would require some changes in the NMEA parser and navigation routines, but nothing that an afternoon of coding can't solve. I don't have any specific advice, since we've never done what you suggest, but the code is pretty well commented and there are no technical barriers that I can think of to do this.
