As autonomous navigation technology advances and the importance of positional information in maritime environments increases, it is necessary to develop alternatives to the Global Navigation Satellite System (GNSS) in consideration of its vulnerabilities. Ranging Mode (R-Mode) technology is emerging as a GNSS backup system, utilizing existing maritime communication infrastructure to provide position, navigation, and timing (PNT) information through a terrestrial navigation system. This paper introduces a test-bed system developed to validate the feasibility and performance of medium frequency (MF) R-Mode technology in the context of South Korea. The MF R-Mode test-bed's transmitters are upgraded from four existing DGNSS systems, and positioning performance was evaluated based on data received in a static environment from actual signal broadcasts.
