A Study on the Approval Process and Criteria for Operation of Ground-Based Augmentation System (GBAS) in Korea

Abstract

Ground-Based Augmentation System (GBAS) is providing precision approach and landing service with aircraft around airport. FAA granted System Design Approval (SDA) of SLS-4000 to Honeywell as the first GBAS category I system on September 2009. Since then, according to their own kind of approval process including System Design Approval, Facility Approval and Operational Approval, USA, Germany, Spain and Australia have approved GBAS category I system which are installed in some airports in order to provide commercial GBAS service. Recently, KARI has also installed GBAS category I system into Gimpo international airport to establish operational technology of GBAS domestically and to validate effectiveness of GBAS system in Korea. This paper introduces overseas trends and activities regarding approval process of GBAS system and presents approval process and criteria appropriate for future commercial operation of GBAS in Korea.

Folded microstrip antenna with isotropic radiation pattern

“…We performed simulations for the antenna in Figure 2(A) with the center frequency 118 MHz (λ: 2542 mm) of the ground‐based augmentation system 4,5 . The simulation and characteristic analysis of the antenna was performed using the MWS analysis software(CST, 2017).…”

Probe feeding was used for the feeding mechanism, and styrofoam was selected as a dielectric material with air-like properties.…”
