摘　　要：为提高民用飞机的综合导航性能,确保RNP运行,提出了一种基于机载RNP性能评估的多源综合导航管理方法。设计了基于导航性能评估的多源综合导航管理方法,研究了综合导航模式和单一导航模式下的实际导航性能估计算法。仿真实验结果表明:实际导航性能算法能够在95%时间内评估导航系统实时误差特性,具有较高的评估精度,而且综合导航管理方法在多传感器配置的飞机中选择最佳的导航信息,满足RNP运行要求。In order to improve the integrated navigation performance of the civil plane and to ensure the safety of RNP operation,a multi-source integrated navigation management method based on airborne RNP performance evaluation is proposed.A method of multi-source integrated navigation management based on accuracy navigation performance(ANP)is designed.The ANP evaluation algorithm of two kinds of navigation mode such as integrated navigation mode and single navigation mode are studied.Simulation result indicates that the ANP algorithm can estimate the real-time error characteristics of integrated navigation system during 95%of flight times.And the multi-source integrated navigation management method can select the best navigation sources based on ANP,which can satisfy the requirement of RNP.
