| 摘 要： | 采用容错技术提高导航系统的可靠性是现代导航技术主要发展方向之一，采用冗余敏感器配置的捷联惯导系统具有成本低、重量轻和可靠性高等优点。利用马尔可夫模型对四余度双轴冗余惯性敏感器配置的导航组件的可靠性进行建模，对敏感器质量、故障检测和故障隔离的误差（包括误警率、漏检率和故障隔离率等）、系统任务时间和系统其它部件的故障概率等因素对导航系统可靠性的影响进行了分析和比较。

| Abstract: | Fault diagnosis has become an issue of primary importance in modern navigation.The redundant strapdoun inertial navigation system has many merit points, such as cheap,light and reliable. In the reliability analyzing, Markov process theory can by applied to describe the original working condition of the system. In the paper, the effects of different system parameters on the reliability of a redundant strapdown system were assessed |
