卫星导航系统运行在复杂的电磁和空间环境中。对导航系统的威胁和防护能力的研究较少。由于缺乏定性数据，很难对其安全性进行分析。本文应用函数依赖网络分析(FDNA)来解决这一问题。FDNA研究攻击直接造成的影响如何通过系统功能节点之间的依赖关系在整个系统中传播。然后，我们才能评估导航系统应用的可操作性。该方法避免了大量的统计实验。充分利用原则数据。提供建设性的决策意见。
Satellite navigation systems are running in complex electromagnetic and space environment. There is few research studies the threat and protect ability of navigation system. Lacking of qualitative data makes it difficult to analyse the security of it. In this paper, we applied Functional Dependency Network Analysis (FDNA) to solve this problem. FDNA studies how the impact caused directly by attack spreads in the overall system through the dependencies between function nodes of system. Then we are able to assess the operability of the application of navigation system. This method avoid considerable statistic experiments. Make full use of principle data. Provide constructive decision making comments.
