This paper presents a method for utilizing State Space Representation (SSR) corrections generated by the Korean national maritime Precision Positioning and Integrity Monitoring (POINT) system, a Precise Point Positioning - Real-Time Kinematic (PPP-RTK) service, with commercial RTK receivers. Specifically, a real-time SSR to Observation Space Representation (OSR) conversion algorithm is designed and implemented. We describe the structure of SSR corrections provided by the POINT system, including satellite orbit, satellite clock, signal bias, ionospheric delay, tropospheric delay, and coordinate transformation parameters. Additionally, we analyze the positioning accuracy of commercial receivers, such as Trimble, NovAtel, and U-blox, using OSR corrections converted from SSR data. The results demonstrate that the converted OSR corrections can achieve the required centimeter-level accuracy, satisfying the performance criteria for maritime applications. Through this study, we demonstrate that the SSR to OSR conversion software, when integrated with commercial receivers, can effectively enhance positioning accuracy, meeting the stringent requirements for maritime navigation.
