ABSTRACT:
An apparatus and method for compensating for the measured variation in bearing between magnetic north as read on a compass and true north as may be determined by juxtaposition with the sun at a given time. Such apparatus and method is particularly useful in vessels or other environments in which there are either or both disturbances in the natural magnetic flux pattern of the earth and natural variations between natural magnetic and true north.
