Investigation and Modeling of Effects of Ionospheric Plasma Bubbles on GBAS Availability

Takeshi Fujiwara and Toshiaki Tsujii

Abstract:	To contribute to the realization of the next-generation air transportation system, Japan Aerospace Exploration Agency (JAXA) is promoting the research and development project named DREAMS (Distributed and Revolutionary Efficient Air-safety Management System). Research and development of high precision and reliable navigation system is one of the most important targets of this project. In this paper, the impacts of the ionospheric plasma bubble on the GBAS availability are investigated. Though the impacts of ionospheric anomalies on GBAS integrity have been researched well so far, the impacts on GBAS availability have not been well investigated. Since the ionospheric plasma bubbles occur much more often than the Storm Enhanced Density (SED) in the regions at low magnetic latitude, its impacts on the availability should be investigated as well as the impacts on the integrity.
