Preliminary Research on Management of Crosslinks of Navigation Constellations and Their Security System

摘要

Crosslinks of a navigation constellation are designed for inter-satellite ranging and communication and autonomous navigation so that the constellation can function continuously without the support of globally distributed ground stations.Crosslinks can also realize some other extended applications.As a significant part of a satellite platform,crosslinks can improve the function of a constellation.However,management problems related to crosslinks have to be solved.This paper discusses the tasks of a crosslink management system and proposes a design of its function and topology based on the characteristics of the crosslinks of the navigation constellation.Meanwhile,the crosslink management model and security protection issues are also discussed.
