Abstract
A method for compensating a magnetic heading includes one or more of obtaining a magnetic heading from a magnetic instrument deployed with an apparatus, determining location data for the apparatus, determining local field data based on the location data, obtaining a magnetic profile for the magnetic instrument deployed with the apparatus, and compensating the magnetic heading based the magnetic profile. For example, the magnetic profile may be responsive to perturbation of the local geomagnetic field by the apparatus, so that the compensated heading is more responsive to a directional heading of the apparatus, when deployed in the geomagnetic field. An apparatus for performing the method is also described, along with another method for calibrating the magnetic instrument when deployed with the apparatus, in order to generate the magnetic profile.
