ABSTRACT Our invention relates to a novel electromechanical method and apparatus for detecting and representing the north direction and/or heading of an object or vessel in analog and/or digital representation. It is a particular object of our invention to derive the magnetic heading of an object or vessel by means in- dependent of stray magnetic fields, nearby ferrous objects and the pitching, rolling and yawing of the location at which the compass is used to an extent hereinbefore unattainable in terms of convenience, accuracy and cost, for reasons including the type of sensor, its remote positioning where desired from the reading position, the electronic detection means and subsequent depiction, digitally, in numerical degrees and/or by analog means, employing points of light on the surface of a screen, cathode ray tube or other area representing the relative positions of the north direction and that of the object whose heading is re- quired.
