How is the yaw angle of an object determined?

Due to the the Earth gravity accelerometers «sense» the down direction. Their measurements are used to calculate roll and pitch angles. Here you'll find the formulas to calculate them. The yaw angle (in this case it's the magnetic azimuth) can be determined due to the Earthâ€™s magnetic field.

When do the roll and yaw and pitch of a magnetic field work?

The roll and yaw and pitch would work when the magnetic field is homogenous and well defined. Earth magnetic field is quite complex and deformed, so you have to know the parameters on various latitudes and longitudes.

How do you measure pitch and yaw of an object?

An accelerometer alone will tell you pitch and roll; not yaw because gravity is parallel to yaw (z) and a magnetometer alone will tell you roll and yaw; not pitch because the Earthâ€™s magnetic field is parallel to pitch (x)*. *Note that the earthâ€™s magnetic field is only horizontal to the earthâ€™s surface at the equator.

What does a 3 axis magnetometer show?

The 3 axis magnetometer shows you the intensity of the x,y,z parts of the magnetic field intensity sorrounding the magnetometer. The roll and yaw and pitch would work when the magnetic field is homogenous and well defined. Earth magnetic field is quite complex and deformed, so you have to know the parameters on various latitudes and longitudes.
