• Since the ICAO decided to adopt the GNSS-based CNS/ATM as a future standard navigation system, there has been much research to guarantee the required navigation performance of CNS/ATM sub-systems (GBAS, SBAS, etc.), mainly in the integrity or continuity aspect. However, it is also important to study the interoperability and natural transition between the old and new nav-aids because of their very different features. Therefore, we focused on the verification of the performance of the new systems, especially GBAS, through comparison with conventional aircraft landing guidance systems such as ILS. For performance verification, we developed the GBAS system and conducted three types of ground tests and several flight tests. In the analysis of the test data, we compared the GBAS navigation solutions with the data collected from the ILS inspection device — Theodolite. From the analysis, we concluded that the developed GBAS system satisfied the Precision Approach Category I requirements in the aspect of accuracy, and was consistent with the conventional aircraft precision approach guidance system.
