Hi. I want to design IMU using MPU9250 and HMC5883L. In MPU 9250 noisy signal coming from magnetometer causes heading oscillations. So I want to use HMC5883L as magnetometer. In the attached image you will see how I should place sensors. (red box- MPU9250, blue box- HMC5883L) . I don't know how I going to calculate rotation angles, etc. in this design because sensors will be placed in different points of drone or robot.
