System is Pi4 4GB, 64bit OS, All latest updates to OS and Openplotter, Pypilot 3.2.13. i have a Waveshare 10DOF sensor consisting of an MPU9250 and a BMP280. I've also tried a GY-91 MPU9250/BMP280 with the same results.
I've gone through (fairly quickly!) the calibration routine in Pypilot, IMU only. I see data in Signal K:
navigation.attitude - shows roll, pitch and yaw
navigation.headingMagnetic - shows the heading in Radians
However the figure for heading and the figure for yaw are identical to 15 decimal places. As I move the sensor the heading changes but so does the yaw. I can understand that yaw corresponds to a rotation about the vertical axis and that a change of course is the same but I am trying to understand exactly why those two figures are identical.
I'm sat at home doing this so maybe that isn't realistic.
Can anyone help me understand this?
Thanks
