一种用于GLS机载设备适航验证的模拟器设计

A simulator design for airworthiness verification of GLS airborne equipment

机载设备是新一代卫星着陆系统(GBAS landing system,GLS)在民航中大规模应用的关键,而适航验证是GLS机载设备必须要解决的问题。针对该问题,文章整理分析与GLS机载设备相关的适航验证需求,提出一种符合相关适航验证规范的模拟器设计方案,构建外部环境仿真模型,并开发模拟器软件系统。对CAT I进近导引信号的生成表明所设计的模拟器可实现预期的设计目标。

Airborne equipment is the key to the large-scale application of a new generation of GBAS landing system(GLS)in civil aviation,and the airworthiness verification is a problem that must be solved before the application of GLS airborne equipment.In response to the problem,the airworthiness verification requirements related to GLS airborne equipment are analyzed.Then,a simulator design that meets the relevant airworthiness verification specifications is proposed,and the external environment simulation model is constructed.Finally,a simulator software system is developed.The generation of CAT I approach guidance signal shows that the simulator designed can achieve the expected design goals.
