Abstract：Instrument landing system is the key navigation equipment for precision approach and landing in civil aviation air-ports.With the rapid development of China's civil aviation industry and the promotion of national science and technology innovation policies,the localization of ILS has become an important strategic goal to achieve a strong country in science and technology and civ-il aviation.Firstly,this paper analyzes the important position of instrument landing system in aviation field and the necessity of local-ization from the course of localization of instrument landing system.Then,the characteristics of instrument landing system at home and abroad are analyzed in detail,and the key factors restricting the localization of instrument landing system are revealed.On the basis of this research,the challenges faced in the process of localization of instrument landing system are further discussed,includ-ing the dependence on imports of core components,insufficient innovation ability and imperfect industrial chain.Finally,the coun-termeasures and suggestions are systematically put forward in view of the above challenges.
