INFLUENCE OF EXTERNAL FACTORS ON TRANSIENT PROCESSES OF MAGNETIC COMPASS AT HIGH LATITUDES
Annotation
A mathematical model describing operation of the card of a ship's magnetic compass, is developed. The influence of external factors on the model coefficients is demonstrated. Results of experimental studies of the influence of low temperatures and small value of the horizontal component of Earth's magnetic field on transient characteristics and a dead zone of the card carried out with three samples of the magnetic compass are presented. Based on the analysis of obtained results, it is concluded that a decrease in the horizontal component of the Earth's magnetic field vector significantly affects the transition characteristics of the magnetic compass, while a decrease in temperature leads to an increase in the transition process duration.
