The author:(作者)aaapublished in(发表于) 2013/12/16 0:34:58 Dr four Lunar dreams： can keep up with the times is we’re lucky
December 14 to become immortal, the third successful visit "features" in the Beijing Aerospace command and control center flight control Hall, a group of Dr Moon dreams of youth are closely watching the visitor's changing of the moon.
Li Lichun: Rover painted "maps"
Dark gray surface, rugged crater sizes of meteorites ... ... On the big screen, a lunar topographic maps in three dimensions to show in front of everyone, and people were participating.
This is not an ordinary image, it restores the true lunar surface environment in real time. Dr Li Lichun is flight control center in Beijing as Rover painted "maps" of people, he told reporters: "just like our usual driving navigation using maps, and Lunar Rover on the moon also needs ' map '. ”
However, the Rover painted "maps" is easier said than done, and if not to prepare an accurate "maps", may bring an immeasurable loss. Li Lichun was more than 10 minutes to complete the more than more than 10 sets of image analysis and processing, and you want to quickly restore a climatological Outlook, on reliability, real-time image processing software and have made a very high degree of automation requirements.
Study on Visual navigation of spacecraft Li Lichun, doctoral graduates volunteered to undertake this important task, Chang-third mission "inspection to detect remote control software" Deputy Chief Designer. He came up with a dozen kinds of image sensing processing solution, worked day and night for software development, within a very short period of time, he developed a Chang received the third probe, image analysis and processing software, implements visited when walking on the moon can be seen and measured.
Do this, he has not met, "Lunar Rover on the moon face obstacles to do? Disruption to do? "And he expected the problem to be solved, for which he presented groundbreaking vision system calibration, which for the first time in our country successful visits of extraterrestrial objects detection new weights have been added.
Korean pines: deep space survey "magic hands"
Day of the year, China's satellite launch for conference rooms at Headquarters, a quiet battle is under way. This is a deep-space measurements to test scene, over more than 10 experts from at home and abroad is to elect the best results through analysis, the results will be directly related to Chang e-rail precision for determination of third mission. Eventually, the Beijing flight control centre to handle data error minimum analysis results to the highest resolution, approved unanimously by the experts. "Your measurement accuracy has reached the international advanced level! "When the ESA experts when thumbs up, Dr Han Songtao a giant smile on his face.
Chang-third mission flight control center in Beijing for the first time responsibility for deep space interferometry data processing tasks, it is the task of the interferometric signal processing centre. Receiving and processing data returned in 380,000 km away, for the flight control center in Beijing for the first time, data processing and analysis the main gang the Korean pines are unprecedented levels of pressure.
"My job is to work throughout the flight control to the forefront, each data are processed is essential. "Dr Han told reporters. For the purposes of data processing and analysis, precision is the core, efficiency is key, especially for deep-space measurement and control. High real-time requirements of data processing, a tiny deviation can cause failure of the entire measurement and control tasks.
During that time, he used to go home at 1 o'clock at night before, less than 7 in the morning and continued to fight. At that time could not sleep at all, eyes closed, a variety of data, the programme is still imprinted on it.
Eventually, he developed the Beijing flight control center measurement data processing software, huge amount of data in the hands of his magic to break one by one, to that end, colleagues gave him a very stylish aliases-deep space survey "magic hands".
Wang Baofeng: let Rover has a pair of "eyes"
"Visual positioning" known as Rovers, "eyes", it directly determines the surface environment information for the first time to the ground. Only a few developed countries have such technologies in the world, empty of its kind in China. This tough a man of iron fell on the shoulders of Visual navigation research and academic leaders--Wang Baofeng.
"Rovers ' eye ' is the basis for exploring space. "Notes on the title page of his work wrote this sentence. Wang Baofeng study abroad starting with the success of inspections investigations, read out a thick stack of information, wrote notes for more than 100,000 words.
A 7-Member "Visual navigation research and innovation team", led by Wang Baofeng successively broke the Rover camera vision system for accurate calibration, image matching, and other difficulties, has designed a pair of Lunar Rover breadth of perspective, "bright eyes".
"Can catch up with the era of space development, is our generation's lucky, only giving people the same on our shoulders, China's space industry will be more brilliant. "Wang Baofeng said.
NG and Thunder: gold medal led by Dr "the moon lady"
On the International Astronautical Congress in September this year, a young scholar fluent in English briefed the experts on Chang-third mission. Aerospace industry-renowned experts from home and abroad have been attracted by his unique insights, his overall Deputy Director Wu Fenglei is the flight control center in Beijing.
Had the highest scores from the International Space University Master Wu fenglei, led teams have distinguished themselves again and again, now also assume Chang, third mandate tracking telemetry command and communication group headquarters flight control the Secretary-General's responsibilities.
Chang e third mission is a whole new challenge, there is no reference, even the failures of our predecessors could not be found! Especially for just taking over Chang-Wu of the task in less than two years Mr Fang was bigger challenges for, in his words, "it's treading on thin ice. ”
Everything from scratch. He made one of his pupils, two principles come to set myself: as long as it is between Chang-er, regardless of their size, he will join in; as long as it is between Chang-er file, he would seriously study ... ...
Tele-operated control is Chang, third difficulty of the task, fenglei, NG stayed a few days in a row, looking at how the route. A new idea surfaced right in front, he quickly called tackling key members of the research group for several days and nights, finally made a breakthrough.
"Aerospace is selected, choose nonstop lifestyle. "Wu Fenglei said," flight control, the whole process is irreversible, only taking off, to enter the earth-moon transfer orbit, fly to deep space ... ... "

12月14日21时，嫦娥三号成功造访“广寒宫”，在北京航天飞行控制中心的飞控大厅里，一群胸怀探月梦想的青年博士正密切关注着这位月球访客的瞬息万变。
李立春：为月球车画“地图”
暗灰色的月面，凹凸不平的撞击坑，大小不一的陨石……大屏幕上，一幅月球地形图立体地展现在大家面前，让人身临其境。
这不是一张普通的图像，它实时还原了月球表面的真实环境。北京飞控中心李立春博士就是为月球车画“地图”的人，他形象地告诉记者：“就像我们平时开车导航使用的地图一样，月球车在月球上行驶同样需要‘地图’。”
然而，为月球车画“地图”谈何容易，如果不能给它准备一份准确的“地图”，可能会带来不可估量的损失。李立春要在10多分钟内，完成对10余组图像的分析处理，并且要快速还原出月貌，对图像处理软件的可靠性、实时性和自动化程度都提出了很高的要求。
研究航天器视觉导航的李立春，博士一毕业就主动请缨承担了这项重任，成为嫦娥三号任务“巡视器探测遥操作软件”副主任设计师。他提出了十几种图像感知处理方案，夜以继日地进行软件开发，在很短的时间内，他就研制出嫦娥三号探测器图像接收分析处理系列软件，实现了巡视器在月球上行走时看得见，测得准。
完成这些，他并没有满足，“万一月球车在月球遇到障碍怎么办？受到干扰怎么办？”，这是他预想并要解决的问题，为此他开拓性地提出了视觉系统自标定方案，这为我国首次地外天体的成功巡视探测增加了新的砝码。
韩松涛：深空测量“魔术手”
今年的一天，中国卫星发射总部的会议室内，一场无声的较量正在进行。这是深空测量数据测试现场，来自国内外的十多名专家正通过分析比对选出最优的结果，这个结果将直接关系到嫦娥三号任务的测定轨精度。最终，北京飞控中心处理数据分析结果以精度最高、误差最小得到了专家的一致认可。“你们的测量精度已经达到了国际先进水平！”当欧空局的专家竖起大拇指时，韩松涛博士脸上露出了灿烂的笑容。
北京飞控中心首次担负嫦娥三号任务深空干涉测量数据处理任务，是任务的深空干涉测量信号处理中心。接收处理38万公里之外传回的探测数据，对北京飞控中心来说还是第一次，数据处理分析主岗的韩松涛感到了前所未有的压力。
“我的工作是整个飞控工作的最前端，每一个数据的处理都至关重要。”韩博士告诉记者。对数据处理分析而言，精度是核心，效率是关键，特别是对深空测控来说。对数据分析处理的实时性要求极高，一个细小的偏差都可能导致整个测控任务的失败。
那段时间，他常常到深夜1点后才回家，早上不到7点又继续奋战。那时候根本睡不着，眼一闭，各种数据、方案一股脑儿涌上来。
最终，他开发出了北京飞控中心干涉测量数据处理软件，海量的数据在他的手中神奇地被一一分解，为此，同事们给他取了个很时尚的别名——深空测量“魔术手”。
王保丰：让月球车拥有一双“明眸”
“视觉定位”被誉为月球车的“眼睛”，它直接决定着月面环境信息能否第一时间传到地面。世界上只有少数发达国家才具备这种技术，在我国尚属空白。这块难啃的硬骨头落在了视觉导航研究学科带头人——王保丰的肩上。
“月球车的‘眼睛’是探索太空的基础。”他在工作笔记的扉页上写下了这句话。王保丰从学习国外巡视勘察方面的成功经验入手，看了厚厚一摞资料，笔记写了足足10万多字。
由7人组成的“视觉导航研究创新团队”，在王保丰的带领下先后突破了月球车相机的精确标定、视觉系统图像匹配等多个难关，为月球车设计了一双视角宽广的“明眸”。
“能赶上这个航天发展的时代，是我们这一代人的幸运，只有让别人同样站在我们的肩膀上，中国的航天事业才会更加辉煌。”王保丰说。
吴风雷：金牌博士情牵“嫦娥”
今年9月的国际宇航大会上，一位年轻的学者用流利的英语向与会专家介绍嫦娥三号任务的相关情况。现场来自国内外航天界的知名专家都被他独到的见解所吸引，他就是北京飞控中心总体室副主任吴风雷。
曾以最高分获得国际空间大学硕士学位的吴风雷，带领团队屡建奇功，而今又担负起嫦娥三号任务测控通信指挥部飞控组秘书长的重任。
嫦娥三号任务是全新的挑战，没有现成的借鉴，哪怕是前人失败的教训都找不到！尤其是对刚刚接手嫦娥任务不到两年的吴风雷来说是更严峻的挑战，用他的话来说，“简直就是如履薄冰。”
一切从零开始。他把自己当成了一名小学生，给自己定了两条原则：只要是有关嫦娥的会，无论大小他都要参加；只要是有关嫦娥的文件，他都要认真研究……
遥操作控制是嫦娥三号任务的难点，一连几天吴风雷彻夜未眠，反复思考该采取怎样的路线。一个全新的构想浮现在眼前，他迅速召集攻关小组成员连续几昼夜攻关，终于取得突破。
“选择了航天事业，等于选择了没有休息的生活方式。”吴风雷说，“犹如飞控一样，整个过程不可逆转，只有起飞、进入地月转移轨道，飞向深空……”
