Architecture and development envision of cislunar space infrastructure
The construction of cislunar space infrastructure(CLSI)can provide basic and universal services for human activities in the cislunar space,including data communications,position navigation and timing(PNT),and situation monitoring for the development of lunar space,which can meet the needs of follow-up major national lunar exploration projects.At the same time,it has strategic significance for accelerating the development of the space industry into the cislunar space,and promoting China's strength in science,technology and aerospace.On the basis of clarifying the concept of CLSI and analyzing the state-of-art development status,the top-level system architecture is proposed for the CLSI,regarding to the needs of major projects and the sustainable development of the aerospace industry.Then,the system services,the system composition,the"cloud-domain-end"network architecture as well as the internal and user interfaces architecture are defined and demonstrated.Finally,with the goal of gradually establishing a technologically advanced and reasonably deployed CLSI by phases and providing universal services that are open,safe,reliable,and operate continuously and stably in the long term,development prospects and suggestions are proposed to provide reference for the development and construction planning of CLSI.
