Compass heading accuracy

Posted by Jose Angel on July 1, 2011 at 9:33am

I'm having some yaw problems and I would like to know if an oscillation of +-4 degrees in the heading value obtained from "CLI / tests / compass" is normal or maybe reveals a faulty compass.

 

I attach a CLI screen capture taken with the quad completely quiet.

    I found a response from Jason in another post stating that:

    "Some compass are kind of noisy. Mine is +- 10 deg noise. That may be causing some issues. But even then my compass works great."

     

    So I assume that my compass noise does not affect general yaw performance.

     

    In any case, I'm interested in confirming if heading value is taken into account to stabilize the yaw or is only useful for navigation purposes?

    Anyone?

    And, is the heading value taken into account to stabilize the yaw? or is only useful for navigation purposes?
