北斗GLS的PBN性能评估和飞行验证关键技术研究

中国民航基于性能的导航（PBN）的主用导航系统应逐步过渡到以北斗为基础，兼容多导航星座的卫星导航系统，推广使用卫星导航着陆系统 (GLS)进近。从根本上解决我国对国外导航系统的依赖。. 本项目基于民航PBN的需求，综合分析北斗卫星导航系统应用于GLS的可能性，研究：影响北斗GLS性能的各项关键技术及指标；GLS导航信号的质量评估方法；北斗GLS在各个飞行阶段的可用性分析；导航数据及飞行数据的处理方法；北斗GLS在民航PBN中应用需要待解决的问题和待改进措施，发挥多频点、多系统的特性，以此提升北斗卫星导航着陆系统的精度、完好性、连续性及可用性性能。

For the civil aviation of China, the primary navigation system of Performance Based Navigation (PBN) should be made a gradually transition to the system primarily based on BeiDou Navigation Satellite System(BDS) and is compatible with multi-navigation constellation. In addition, an approach based on GNSS Landing System (GLS) will be promoted to use. The realization of PBN based primarily on BDS will fundamentally solve the dependence on foreign navigation systems in China.. The work of the project will be begun with analyzing the PBN specific requirement in civil aviation industry, the possibility that BDS apply to GLS will be analyzed compositely. First, some indexs and Key techniques that affect the performance of GLS BDS-based will be studied. Second, the methods of quality evaluation for space navigation signal should be studied as vital the first. Thirdly, around Total System Error of GLS, the support case and availability of GLS in fight will be analyzed. Fourthly，the data processing methods navigation datum and flight datum will be researched. Finally, some key problems which need to be solved and perfected in PBN application of civil aviation will be proposed by analyzing the performance of GLS BDS-based. Multi system characteristics and Multi frequency characteristic are brought into play to promote precision, integrity, continuity and the availability of GLS BDS-based.
