Modeling and Analysis of the Threats to GNSS
Wang Xun Zhang, Hong Tao Hou, Pai Peng, Wei Ping Wang · Advanced materials research · 2013
The vulnerability of the global navigation satellite systems (GNSS) makes it susceptible to a variety of threats, so it is significant to study the effects of each threat on GNSS performance. To analyze the impacts of different threats, a dynamic master logic diagram (DMLD) based modeling and analysis method was presented. First the relationships between threats and GNSS performance were built through a quadric associations by DMLD symbols, then qualitative and quantitative analysis was done via DMLDs great reasoning power, at last qualitative and quantitative analysis could show engineers and researchers the effects they concerned about and also could support the improvement of GNSSs defense and protection capability. The DMLD based method provides engineers a feasible way for threats modeling and analysis.
