When I look at my boat graphic in OpenCPN it is constantly spinning, When I look at the instruments in OpenCPN (GPS Compass) it is varying all over. Looking at Signal K, this could be navigation.courseOverGroundTrue - which varies all over the place in SignalK. The Imu based IMU.compass (navigation.headingMagnetic?) seems to be stable to the second decimal place when I look in both Pypilot and SignalK. I am currently on land, will this correct itself once I get sailing or should I be looking at the IMU data In OpenCPN?
