Abstract This paper presents a reconfigurable Global Navigation Satellite System (GNSS) signal generation simulator that supports multi-constellation and multi-frequency signal generation, including Korean Positioning System (KPS) civil candidate signals in the L6 and S bands. The generator allows flexible configuration of Pseudo Random Noise (PRN) code, modulation, and navigation message. To validate the performance of the simulator, digital Intermediate Frequency (IF) signal tests and Over the Air (OTA) experiments using a Software Designed Receiver (SDR) were conducted. The results confirm successful signal generation, acquisition, tracking, and positioning. Despite interference in the S band, the generator can be effectively applied for candidate signal evaluation and future KPS signal development.
