title: gyro, accelerometer, magnetometer and Kalman filter
body: <p>I want to use gyro, accelermeter and magnetometer to get a full smooth rotation in 3 axis.</p>
  
  <p>The first problem is that my outputs individualy has very noise and I want to know how can I remove it.</p>
  
  <p>The second problem is the gyro drift that I think it should solve with Kalman filter.</p>
  
  <p>The third problem is the accelerometer. If I combine the gyro and accelermeter when I move the device without rotating the device the output will change. Is Kalman filter can remove the moving effect from output too?</p>
