摘　　要：为适应未来美国深空探测的任务,此前美国NASA(National Aeronautics and Space Administration,国家航空航天局)对它的深空网发展的技术现状与能力进行了评估,梳理出了它们在未来深空任务中上下行通信速率需求,从而制定了美国下一代深空网的发展战略。针对此战略,梳理分析了美国深空网近年在深空通信导航领域开展的多项重大技术革新与演示验证试验,并从中剖析总结出了它的下一步的技术发展路线,期冀为我国深空测控网技术发展策略的制定提供参考。To meet demand for future deep space exploration,National Aeronautics and Space Administration （NASA） has evaluated the current technical performance of Deep Space Network （DSN）〉 and the future information rate for uplink and downlink has also been predicted. With this foundation, the evolvement strategy for the next generation DSN has been established. This paper gives a general summary of the significant technical inno-vations and demonstration results of NASAJs deep space missions in the past few years and distilled DSNJs technical roadmap for the future,aiming to give reference to technical evolvements of China’s deep space Tracking,Teleme-try and Command （TT＆C） network.
