Abstract:	There have been many researches to guarantee the required navigation performance of the CNS/ATM sub-systems (GBAS, SBAS, etc.) mainly in the accuracy or integrity aspect. However, it is also important the study about the interoperability and natural transition between the old and new nav-aids because of the very different features of them. Therefore, we focused on the verification of the performance of the new systems, especially GBAS, through the comparison with the conventional aircraft landing guidance system such as ILS. For the verification, we developed the GBAS system and conducted the ground tests, flight tests, and integrity monitoring tests. Additionally, in the analysis of the test data, we compared the GBAS navigation solutions with the data which are 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 had the consistency with the conventional aircraft precision approach guidance system.
