Abstract
A compass is a very important device onboard a ship. Using a compass, an operator is able to determine ship direction correctly, which contributes to fuel economy and safety. A compass was firstly invented in China during the reign of the Song dynasty to indicate the direction for travelling in a desert. Currently, compasses of different types are used for various purposes. There are satellite, magnetic, electrical, and other compasses. Up-to-data multifunctional highly reliable compasses are fabricated by Japanese, Russian, American and other producers. Despite the incredibly large offer of various compasses, the existing models are unsuitable for small marine vessels, and in most cases the price is very high. This article describes the results of research, hardware development and programming for the Maritime Digital Compass Repeater (MCRC). Algorithms of devices programming and actual results of MDCR tests are presented. MDCR design and tests results revealed that this repeater fully meets the technical requirements and may be installed and used shipboard. MDCR design is distinguished with reliability and beauty, stability in operation, simplicity to install and monitor. MDCR is programmed according to the optimal algorithm with two functions indicating the ship’s azimuth and its turning rate. The research finding can contribute to an increase in the autonomy of Vietnam in marine technology. The equipment designed and developed is being implemented onboard many Vietnamese ships. To achieve the goals of the study, the authors applied both theoretical and empirical methods. The practical importance of the study is in the possibility to equip small ships and vessels navigating along internal routes with the designed compass system.
