Key techniques and current research status of INS/CNS integrated navigation on intermediate-range missile

The INS/CNS integrated navigation technology, having the characteristics of the whole-process autonomous controllability and non-accumulation time-varrying error, remains a hot and challenging issue in the field of intermediate-range missile navigation. There has been an increased research interest on this issue around the world. Therefore, investigating this issue is of great theoretical and practical importance. On basis of the current research status of the technology, the technical principles and some key techniques such as wild-field starlight sensor, star patterns identification, starlight refraction are analyzed and summarized in this paper. Finally, the development trends of the INS/CNS integrated navigation technology on intermediate-range missile are pointed out.
