分布式航天器系统的测控网络架构与关键技术

TT&C Network Architecture of Distributed Spacecraft System and Its Key Technology

针对航天器测控资源消耗随目标数量的增长而快速上升的问题,提出了分布式航天器系统的测控网络架构构想,并梳理了关键技术及解决途径。该网络从逻辑上分为控制面和业务面,两个面分别采用不同的组网方式各司其责,通过业务面的不同子网同时响应多个不同应用,从而实现了编队航天器等集群目标同时测控与信息交互的目标,解决了传统测控中心集中式带来的问题,满足了测控与管理在可达性、可靠性等方面更高的要求。

With the increase of spacecraft targets in quantity,the rapid growth of TT＆C resource consumption becomes a severe problem.In this paper,the conception of the TT＆C network architecture of distributed spacecraft system is introduced.Afterwards,some key technologies and corresponding solutions are compiled.To solve the problems of the traditional concentrated TT＆C mode,the network is logically divided into the control plane and the business plane which uses different networking modes to perform their respective duties.To achieve the TT＆C and information interaction for the spacecraft cluster targets,different subnets of the business plan simultaneously respond to different applications.Thus,it can meet the higher demand in the accessibility and reliability of TT＆C and management.
