嫦娥二号卫星是中国第2颗月球探测卫星,设计主要目标为先期验证后续月球着陆任务中的部分关键技术.技术试验分系统是嫦娥二号各分系统中唯一全新设计的分系统,以满足技术验证和兼顾拓展的需求.本文从分系统组成、主要设计思路、分系统设计、飞行试验情况等方面介绍技术试验分系统的设计与实现情况.技术试验分系统集中了嫦娥二号卫星绝大部分新研单机产品,并负责完成嫦娥二号任务多项工程目标.此外,分系统设计兼顾了远距离深空通信和天体成像需求,预留了扩展能力.嫦娥二号卫星的飞行结果表明技术试验分系统圆满完成了既定的工程任务目标,并在后续拓展任务中利用扩展能力成功对图塔蒂斯小行星成像.
Chang’e II satellite is China’s second lunar probe, the main goal of the design is to verify some of the key technologies in the follow-up lunar landing mission in advance.Technical test subsystem is the only newly designed sub-system in Chang’e II subsystems to meet Technical verification and taking into account the needs of expansion.This paper introduces the design and implementation of technical test subsystem from the points of subsystems, the main design ideas, subsystems design, flight test conditions, etc. The technical test subsystem focuses on the large Chang’e II satellite Part of the new research stand-alone products, and is responsible for the completion of a number of Chang’e tasks a number of projects.In addition, subsystem design takes into account the needs of long-range deep space communications and celestial imaging, set aside the scalability.Chang’e II satellite flight results show that technology The experimental sub-system successfully completed the established objectives of the engineering task and successfully expanded the Tutatis asteroid with the scalability in the subsequent extension missions.
