In this study, the impact of the drone racing system, which is expected to be widely used in existing domestic radiodetemination systems, was investigated. In considering the race band of the drone racing system, two adjacent channels (Channel 1: 5,658 MHz and Channel 2: 5,695 MHz) to the radiodetemination system were selected. The simulation analysis results show that protection distances of 7.38 and 0.211 km were required to satisfy the requirement of −10 dB of I/N for Channels 1 and 2, respectively. When using the center frequency (5,637 MHz) of the radiodetemination system, a protection distance of 57.65 km was required. Therefore, it is necessary to select an appropriate frequency and distance for drone racing to ensure the protection of existing radiodetemination systems.
