摘　　要：地基增强系统(GBAS)能够弥补传统导航系统的诸多缺陷。为了评估GBAS系统的导航性能和系统性能,验证GBAS进近服务在不同运行条件下的总体性能,通常需要展开相应的飞行测试。考虑到GBAS飞行测试需要结合特定的测试设备和运行环境来进行,过程一般十分复杂。在实验室环境下,结合Flight Gear和Matlab软件,采用仿真数据代替实测数据,仿真验证GBAS系统的I类精密进近(CAT I)与着陆阶段所需导航性能(RNP)。仿真结果表明,GBAS系统可以满足CAT I进近和着陆的性能要求,能够为基于北斗的GBAS技术在民航领域中的推广提供解决方案。GBAS can provide a remedy for many shortcomings of traditional navigation systems.To evaluate the navigation performance and system performance of GBAS and to verify the integrated performance of GBAS approach services under different types of operation conditions,it is usually necessary to conduct corresponding flight tests.Considering that GBAS flight tests need to be conducted in combination with specific test equipment and operating environment,the process is always very complicated.Therefore,simulation data is adopted instead of real-collected data to simulate and verify the landing period Category I Precision Approach(CAT I)and Required Navigation Performance(RNP)of GBAS in a laboratory environment with Flight Gear and Matlab software.The simulation results show that GBAS can meet the CAT I approach and landing performance requirements and can provide a solution for the promotion of Beidou-based GBAS technology in the civil aviation field.
