地基增强系统(GBAS)飞行验证方法研究

为改善终端区导航服务性能，支持 GPS 差分精密进近和着陆，国际民航组织提出了地基增强系统(GBAS)。为验证地基增强系统是否满足民用航空运行标准，需要对其进行飞行验证。本文详细讨论了对 GBAS 系统的飞行验证过程，包括地面子系统和机载子系统的平台建设， 以及飞行验证方法。试验结果表明被测 GBAS 系统符合国际民航组织颁布的 GBAS 运行标准，满足一类精密进近要求。

Research on Flight Inspection Methods for GBAS

International Civil Aviation Organization (ICAO) presented the Ground Based Augmentation System (GBAS) to support differential GPS precision approach and landing and improve the performance of the navigation service at a terminal area. It needs to be validated whether the GBAS meets the requirements of the civil aviation standard. The paper presents a detailed discussion of the processes of the flight validation, including the construction of ground subsystem and airborne subsystem and their methods of flight validation. The result has shown that the testing GBAS is in accordance with the requirements issued by ICAO, and can provide the service of CAT I precision landing.
