Workings of an Autopilot
#2

  1. It depends.   Moving the rudder for every wave depends on the boat, the wave size, and the desired results.
  2. pypilot is using the data, but the gyros are essential.   The accelerometers are combined with the gyros and compass sensors in a kalman filter.
  3. The basic pilot is using an extended PID filter, but I am working on artificial intelligence.   It probably has less benefits than you might expect though at least for most users.
  4. The older tiller pilots often used mechanically gimbaled fluxgate compass which is by now about 30 years old and very susceptible to resonance.   Imagine hanging the sensors to tilt compensate them and how they can swing around and make the boat steer in S which further causes them to swing around. Mechanical wind vanes have this same issue. Those tiller pilots do not have accelerometers and the rate of change is determined from compass alone which gives poor course holding.
  5. pypilot sends and receives both signalk, and nmea0183, but it directly commands a motor controller which moves the rudder.   To use older tiller pilots you would remove all of the electronics and directly wire the motor to a pypilot motor controller.
