USE OF ARPA TO INDEPENDENTLY DETERMINE SHIP’S SPEED AND COURSE UNDER GPS JAMMING CONDITIONS

Dilyan S. Dimitranov

The safety of navigation is of an utmost priority for maritime officers, especially in conditions where the GPS signal is jammed or unavailable. The growing threats of electronic interference and GPS jamming pose significant challenges to modern maritime navigation. The Automatic Radar Plotting Aid (ARPA) has proven to be a critical tool for navigation due to its ability to process real-time data and provide solutions for a wide range of navigational tasks. This article examines the potential of using ARPA to determine a ship”s course over ground and speed over ground by employing navigational simulators for experimental purposes. The primary focus is on developing and testing a methodology for utilizing ARPA to reduce dependency on GPS. Navigational simulators provide a safe and controlled environment for exploring and validating innovative approaches to ARPA applications. The results demonstrate high accuracy in determining course and speed, regardless of meteorological conditions or the positioning of navigational landmarks. The study confirms the potential of ARPA for application in scenarios involving electronic interference.
