Abstract. Results of development of new means for testing magnetic compasses in a dynamic mode are presented. The effect of external influencing factors on a ship's magnetic compass error, caused by the ship's pitching, is shown. Two stands, developed for simulating the impact of rolling on the card of a magnetic compass, including the case of high latitudes conditions, are proposed. A method for assessing its dynamic error under an action corresponding to the actual pitching of the vessel is developed. Particular attention is paid to the stand for evaluating the efficiency of the magnetic compass correction system. Based on the analysis of the results of experimental studies, it is concluded that the developed stands can be used to assess the errors of any magnetic compass.

Keywords: stand, magnetic compass, error, rolling, high latitudes, small value of the Earth's magnetic field horizontal component
