面向空间分布式星群的组网与传输控制技术研究

As a nouveau space technology which applying swam intelligence, satellte swarms consists of a mass number of small-class, low-weight, low-power spacecrafts like pico-satellites,nano-satellites。Spacecrafts work collaboratively to comlete a series of space mission. Due to satellite swarms have low-cost,strong-survivab-.ility,self-orgenization,reconfigurability and clean features,it has a promissing military and civilian applications. Besides all advantages of satellite swarm, applying it has difficulties such as (1) avoding satellite swarm nodes secessions and collisions, (2) considering and applying self-organizing management features of satellite swarm to solve monitoring problems caused by large telemetry and telecommand data, (3) the energy of satellite swarm nodes are extremely restrited , consider using low-power wireless communication to establish inter-satellite links between nodes. Aming at difficulties above, we puts forward 3 research thoughts, which are the swarm configuration methods adopting fish-swarm algorithm and virtual potential field method, the in-swarm efficient QoS routing and optimization of satellites and ground . In addition of theoretical work, we will setup a simulation environment , and using multi-satellite monitoring data to verify the efficacy and efficiency of theoretical results and key techniques. The project has good scientific significance and appicable prospects , and will provide thoughts and approches for satellite swarms in our application and development of TT&C.

作为一项新型航天技术，星群由大量小体积、低重量、低能耗的皮、纳等微小卫星组成，以协同方式完成一系列空间探测任务。相比于传统的卫星系统，其造价低廉，抗毁性强，有较强的自组织性、重构性、洁净性，具有更高的军民应用前景。然而，星群面临以下技术难点：（1） 保证星群内部节点稳定分布和正常通信，避免节点脱群和碰撞；（2） 在考虑星群结构特点和各种通信约束基础上，设计满足星间通信QoS要求的路由算法 ；（3）微小卫星的供能受限，需尽可能减少星地高频通信带来的高能耗。因此，本项目将立足三方面开展研究：基于虚拟势场和人工鱼群算法的星群构型方法、 面向星群系统内星间通信的高效QoS路由协议和 实现通信能量效率优化的星地间通信技术。 在理论研究的同时，将建立仿真环境和利用原型系统验证理论成果和关键技术的有效性。本项目研究具有很好的科学意义和应用前景，将为星群在我国的应用与测控技术发展提供思路和方法。
