Short summary
Absolute magnetic measurements require the vertical and the geographic north as reference directions. We present here a novel system able to measure the direction of the magnetic field and of the vertical and true north. A design of a north seeker is proposed that takes into account sensor bias as well as misalignment errors. Different methods are derived from this model and measurement results are presented. A measurement test at high latitude is also shown.
