A Method for Measuring the Magnetic Heading of a Vessel in High Latitudes and its Implementation in the Azimuth-KM05D Compass

A method is proposed for measuring the magnetic heading of a vessel in high latitudes, which consists in the extraction of signal proportional to the magnetic compass error at rolling, and its compensation in resulting measurements. The error signal is formed with the use of the yaw rate and a special computing algorithm. The paper describes the proposed algorithm as well as the Azimuth-KM0SD magnetic compass in which the proposed measurement method is implemented.
