| 摘要: |
| 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。 |

| Abstract: |
| 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. |
