Preliminary research on management of crosslinks of navigation constellations and their security system

Abstract

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. © 2013 Tsinghua University Press, and Springer-Verlag.
