China News Agency, Beijing, December 1 (open Ouyang Yu Qi Dengfeng) Chang the third probe, will be held on December 2, at the Xichang satellite launch Center. Mission control communications command long Chen Hongmin, the Beijing Aerospace command and control center, said: "we have prepared well prepared."
Beijing Aerospace command and control center is the mission command and control, orbit control and data processing center and mission control communications headquarters are located.
Chen Hongmin said: "during the nearly 3-year mission to prepare for during the programme plans we have written tens of thousands of words, new edition has more than 1 million lines of software code, organized dozens of construe counselling conducted dozens of system test and upgrade was performed on a wide variety of hardware devices".
Chen Hongmin said that at present, Chang-third mission control work is all ready to go.
From the goddess the third launch in less than a day's time, at present, the technical condition of all flight control Hall has frozen, all the participants are at the end of the rest.
This mission is China's first soft landing probes introduced in extraterrestrial objects, task technology, State of the new, flight control of technical difficulty is unprecedented. According to the Chief Engineer of the Beijing Aerospace Control Center introduced Zhou Jianliang, the mission flight control work "three-high": a condition with brand new, equipped to deal with demanding; remote-operation binding complex, flight control with high precision system interactions, Lander and visited two high degree of synergy.
Kashi and jiamusi, two of China's new deep space station will also participate in mission control for the first time, Beijing's newly-built remote operation Center and deep space interferometry system will first appear in the task.
"In response to these difficulties and new features, broke through the center of Beijing high precision surface Visual positioning, dynamic mission planning Moon patrol, patrol walking path planning and control and other six key technologies, fully equipped with the ability to perform the task. "Zhou Jianliang said. (End text)

中新社北京12月1日电 (欧阳开宇 祁登峰)嫦娥三号探测器将于12月2日1时30分，在西昌卫星发射中心发射。任务测控通信指挥部指挥长、北京航天飞行控制中心陈宏敏表示：“我们已做好万全准备”。
北京航天飞行控制中心是此次任务的指挥调度、轨道控制和数据处理中心及任务测控通信指挥部的所在地。
陈宏敏说：“在长达近3年的任务备战期间，我们撰写了几万字的方案预案，新编了百余万行软件代码，组织了几十次的串讲辅导，进行了几十次的系统联试，同时对大量的硬件设备进行了改造升级”。
陈宏敏表示，目前，嫦娥三号任务测控工作已全部准备就绪。
距离嫦娥三号发射还剩下不到一天的时间，目前，所有飞控大厅技术状态已经冻结，全体一线参试人员正在进行最后的休整。
本次任务是中国首次在地外天体实施软着陆探测，任务技术状态之新，飞控技术难度之大均前所未有。据北京航天飞行控制中心总工程师周建亮介绍，这次任务飞控工作有“三高”：技术状态全新，处置能力要求高；遥操作约束复杂，飞行控制精度高；系统交互多，着陆器和巡视器两器协同程度高。
中国新建的喀什和佳木斯两个深空站也将首次参加任务测控工作，北京新建成的遥操作中心和深空干涉测量系统也将首次在任务中出现。
“针对这些难点和新特点，北京中心先后突破了高精度月面视觉定位、月面巡视动态任务规划、巡视器路径规划与行走控制等六大关键技术，完全具备执行任务的能力。”周建亮说。(完)
