KARI IMT 시스템의 GBAS 보정정보 검증시험

Korea Aerospace Research Institute (KARI) has implemented an integrity monitor testbed (IMT) to provide archived GPS data and test results for integrity monitoring algorithm development. To verify that the system is implemented based on international standard requirements, this paper represents the basic functional verification test results of the implemented testbed as a GBAS reference station. It compares the IMT generated GBAS message fields with those of PEGASUS, which is a baseline toolset accepted by international GBAS experts, to show the validity of the correction information. It also verifies the integrity and availability of the system through analysis on GBAS user data in the range and position domain.
