I saw lot of topics with the same title but answers are different.
I have a magnetometer in my phone which give me the components of magnetic field in direction of X, Y, Z.
If my phone lays on a table the 'z' axis points up. (see the picture below). The values of magnetometer are: ~15 microT in X direction, ~8 microT in Y direction and ~-55 microT in Z direction.
Which of the following angles can be determined using datas of magnetometer? Roll, pitch, yaw? And how?
Thank you, Robert
