天基通信与太空射电望远镜功能一体系统

摘要： 针对现有地基深空通信系统存在深空通信距离不够远、数传速率不够高等缺点，提出一种基于分布式协同控制的天基主动深空通信与太空射电望远镜功能一体系统.该系统部署在地球静止轨道上，由1颗馈源星、1颗中心星和4294颗小卫星（单元星）通过精密编队和在轨自主组装的方式构成，一体化集成天基主动深空通信功能和射电天文望远镜功能.该系统可以为深空探测器提供一个星地高速中转站，由于其部署在地球静止轨道，几乎不受大气云层影响，可以大幅度提升深空探测通信支持距离和数传速率，且能使射电天文望远镜的分辨率和灵敏度提升1~2个数量级.

Space Based Communication and Radio Telescope Functions Integrated System

Abstract：In view of the shortcomings of the existing ground based deep space communication system, such as insufficient communication distance and insufficient data rate in deep space, a space based active communication and space radio telescope function system based on distributed cooperative control method is proposed. The system is deployed in GEO, consisting of a feed source satellite, a central satellite and 4294 unit satellites, through a precise formation and on orbit assembly. The system integrates the functions of space based active communication and radio astronomy telescope. The system can provide a deep space station for deep space detector, due to deploying in GEO, no atmosphere and cloud, which can greatly improve the communication distance and data rate of deep space exploration. What’s more, resolution and sensitivity of the radio telescope can upgrade 1 2 orders.
