Title: Analysis of Galileo Navigation System Dilution of Precise Based on Inter Satellites
Abstract: The article probes whether Inter Satellite Links can improve the anti-attack capability of navigation system.For the reason that the traditional Minimum Distance Algorithm needs more changing times,this article put forward an algorithm of building ISLs that only requires littler time of delay and times of changing links.Under the condition that a satellite fails to work,it acquires dilusion of precision variety of observation station after constituting ISLs based on the proposed algorithm in Galileo Navigation system.At last,it drew a conclusion by comparing and analysing simulation results.The experimental results show that ISLs can modify positioning error,improve positioning precision and enhance anti-attack capability of navigation system.
