复杂干扰环境下的卫星授时接收机加固技术
GNSS timing receiver toughen technique in complicated jamming environments
摘要
Abstract
The threat models and spoofing attack detection technology about navigation satellite timing receiver were summarized.Combined with the operating principle and characteristics of timing receiver,a general framework of timing receiver reinforcement technology was presented. On this basis,two interference detection methods of clock aided method and network aided method were proposed according to the analysis of development tendency of timing receiver reinforcement technology.The former took the advantage of multi satellite clock difference redundancy and the local clock characteristics, while the latter took the advantage of the GNSS timing receiver network with the characteristics of data communication and wide coverage.The interference detection results can be used to integrity assessment and guide the GNSS timing receiver working mode,thus improving the satellite timing reliability and integrity in complicated interference environment.关键词
