Abstract

To ensure consistent navigation services despite GNSS signal disruptions, Korea is developing the R-Mode system. This study focuses on enhancing the simulation accuracy of the MF R-Mode system's performance by integrating data from the Eocheong transmitter with existing data from the Palmi and Chungju transmitters. Additional measurements from these three transmitters were gathered using the DARBS receiver to model the Time-of-Arrival(TOA) variance. Analysis of this data facilitated the calculation of new constants and transmitter specific jitter values, which were then used to determine coverage areas based on the updated parameters.
