Abstract
The purpose of this research work is to conduct experimental research on the accuracy of three types of compass systems: UKPM-M magnetic compass, SSC200 hardbody digital compass, and PGM-C-009 gyrocompass. The study was carried out in Amur Bay. The heading was measured when the study vessel was controlled by the automatic steering device and manually, under no waves, seaways, and free driving. The data obtained were analyzed using spectral analysis. Based on the accuracy measurements, we considered the possibility of using the most accurate data about the heading as the input for the automated vessel steering system.
