摘　　要：国际民航组织提出了未来空中新航行系统,所需导航性能技术是其中关键的技术.文中提出了一种针对所需导航性能通用的完整性和连续性分析方法及分析过程.分别以单套导航系统和余度配置的惯性/卫星组合导航系统为例,详细地分析了两种配置的完整性和连续性.分析结果说明,整个组合导航系统的完整性和连续性与系统的配制结构有关,仅增加导航模块单元的数量不能改善整个系统的连续性,导航显示单元与导航计算机的配置结构同样影响到完整性和连续性的设计结果.结果显示,三余度组合导航系统、二余度导航显示模块、二余度计算模块配置的结构能够满足RNP-0.5的完整性、连续性设计要求.This paper presents a general analysis method （process） of integrity and continuity based on the RNP technology which was sponsored by the ICAO （International Civil Aviation Organization）. The integrity and conti- nuity results of two types of system configuration are obtained by detailed analysis on navigation system configuration and redundant INS/GNSS system. The results show that whole system＇s integrity and continuity has relationship with structure configuration. The system continuity is not improved by merely adding navigation modula. Other rel- ative devices, for example, navigation displays and navigation computers also affect integrity and continuity of sys- tem. Also, the three-ply INS/GNSS system, dual navigation displays and dual computers design configuration ean meet integrity and continuity requirements of RNP- 0.5 （required navigation performance）.
