A high precision magnetic compass based on a stationary Hall probe and a spinning two-poles mu-metal field concentrator. The spinning poles lead to an oscillating magnetic field at the location of the Hall probe. The Hall probe sensitivity direction is oriented at an angle of 90 degrees to the rotation axis of the device. A second harmonic of oscillating component, or double frequency, of the signal from the probe, synchronized with the device rotation, is used to align the axis of rotation to be parallel to the magnetic field. The device does not require prior calibration. It is insensitive to drift of the probe parameters and can provide an angle with precision equal to or better than a 0.05 degree.
