Ah yes China where children get run over by vehicles and animals are abused oh and not to mention they also have chinese rule over tibet where tibetans are setting them selves on fire for people to notice but no one cares..
中国还有孩子被车辆碾过，动物被虐待，西藏人民被侵略被奴役，这些事情怎么没人关注，没人报道？

Would the world be a better place if Hitler had developed the atomic bomb before the USA?
Some of you morons will, of course, say yes. But any rational person will agree that keeping a technological advantage ensures peace, tense as it may be.
假如当初希特勒先一步发明原子弹世界将会如何？你们这些白痴好好想想吧。任何理性的人们都会相信把技术掌握在那些负责人的国家手里是安全的。

China makes spacecraft? are you trying to make me laugh... I thought they could only make stuffs for Dollar Stores and Walmart in America!!!
中国制造的太空船？你在开玩笑吧？太可笑了。中国出了在美国制造债务和沃尔玛还会干点别的什么吗？

Don’’t kid yourself, all Chinese made stuff is not bad quality.Most of you obviously have not been there.I worked there for several years.China has a lot more than you can imagine.
楼上你别那么搞笑好不好，我认为中国制造质量还是不赖的。你们这么说是根本不了解中国。我曾经在中国工作过几年，中国绝对比你能想象到的还厉害。

For people who think China is a new growing power, think about it...China has ALWAYS been a super power, but a rather quiet one. They invented explosives but they used it for fire crackers while west used it for bullets and missiles. They had paper and written literature when Europeans were living on tree tops. They built the Great Wall and, the Grand Canal, palaces, and used fine china and wore silk when the Europeans lived on caves and wore animal hide.
Read history, the Chinese had the most powerful navy of its time and they took the navy to neighboring countries to show them what they’’ve got so they wont mess with them, but never actually used the navy.
Only recent colonization and industrialization and communist influence set China on the back foot for a period of time, now they are rising up to where they always have been.
我很奇怪为什么很多人都把中国看做是一个新兴的强权。实际上中国一直都是一个超级大国，只不过他们相对比较低调而已。他们发明了火药和火箭，只不过他们用来制造爆竹和焰火，而西方人用来制造炸药。当西方人还住在树顶上时他们就发明了纸张和文字。他们建造了长城，大运河，富丽堂皇的宫殿，精美的瓷器和丝绸，而这个时候西方人还住在窑洞里，穿着兽皮呢。
看看历史，中国人曾经拥有世界上最强大的海军，他们庞大的船队访问了几乎世上所有的国家，可是他们去那儿只是为了展示中国的诚意和皇恩，而不是去占领征服他们。
只是最近的一段时间，由于殖民主义，工业化和共产主义的影响，中国才暂时沉沦了，如今，中国正在重新崛起以达到他们以前的高度。

And good thing Obama is dismantling our space programs. All so he can continue to fund reparations to the blacks.
我们的奥巴马正在停止太空计划，他唯一能做的就是不断地把钱拿给他那些黑人兄弟。

Daniel said the truth. It's not unavailable to be unarmed. You can easily deploy N bombs on a space station. No NMD can protect from this. That's why Reagan was very nervous about SU.
这不可能不是个军事装备。在空间站里面装置核武器是很容易的事情。没有什么NMD可以抵抗这个。这就是为什么当年里根对苏联那么紧张的原因了。

USA is worried about china's space program having military links? So... NASA has no military links? Tech from NASA doesn't go to help the USAF and US Navy? NASA doesn't launch military Satalites, wow, thats good to know... i was worried there.
美国担心中国会利用太空来进行军事目的？这样的话，NASA就没有这么干吗？谁敢说NASA跟美国国防部和军队就没有一丝的联系？谁敢说NASA从来就没有发射过军事卫星？你们骗鬼去吧。

Yep soon every nation except America will have a space program.
Just think ware the unlimited resources up there will go, not to the USA if things keep going the way they are.
接下来世界上所有国家都会进行太空项目了，除了美国。
想想他们有多么巨大的资源和能力来做这个事情啊，可美国不行，如果我们继续这样下去的话。

We America Stop sending aid to all foreign countries, especially the jews, then we will be in MUCH BETTER shape.
中国如今能做这些还不是那些贪婪的美国公司给他们投资给他们工作。
强烈呼吁美国停止向任何国家的援助，特别是犹太人，这样我们才能好过点儿。

看了一下，看来美国也有“愤青”和JY，当然，回复的人里面中国人也不少，应该还有的是自带干粮的“五毛”吧......
不管在哪里，人类社会都是有大部分的正常人、一小部分脑残和一小部分心理阴暗的人组成的。
嗯，人类需要进步。
- -- 系统屏蔽 --。
通信用电磁波是直的，如果在地面上，要一直能看到卫星并且传信号给它，要设10多个地面站，每个比如30个经度设一个，这样每个站只能看到卫星过顶，但是站站接力就能一直和卫星直接通信。 可是我国没有那么多站，所以第一个解决办法就是用船，所谓的航天测控船，这样可以各个海域都有一艘船，部分的解决了问题。
可是如果把这个观察点搬到太空里，站的更高自然覆盖面更广，这样3颗卫星就可以全球覆盖了，即使卫星在北美上空，我们也可以通过中继卫星和它联络，就解决了通信问题.
能力相当的俩人，面对同一份工作，接受不接受，选择未必相同
所以您那句话挺好，离开的…留下的…对吧
是一种真正的幸福，如同痴迷音乐的去作曲，喜欢历史的去考古，钻研力学的去造桥。探索浩瀚的宇宙是无数人孩提时的梦想，却只有极少数人最终能坐在那里以职业的方式实现它。
俺所知道的，下面荒岛已经说了一部分，俺就俺所知道的补充一下，许多是俺猜的。
天链一号主要解决的应该是卫星与卫星之间通讯，就是卫星上的信息先送到天链一号上再传回地面，传回地面应该也可以经过另一颗天链一号中继。现在的两颗应该是都放在中国大陆能看到的地方，可以直接传回地面，如果发第三颗就得经前两颗接力了。
飞船一般在350公里、照相侦察卫星也都在七百公里以下的低轨道上。按700算，地面站视野如果是左右60度，一次能监测卫星的飞行距离也就一千二百公里左右。如果要在地、海面上能全面监测低轮道卫星，地、海面上就得密布地面站、船，最大间距不能超过一千二百公里，俺不会算球面，具体要多少地面站不知道，俺猜一百个打不下来。
天链一号是在同步轨道上，有三颗就能复盖全球。当然愿意的话也可以使用其他轨道，但必须是几万公里以上的高轨道，否则就需要增加星数才能复盖全球。因为星上的电源功率有限，需要用增益较高的天线对准卫星和地面站，卫星是不断地动着，在卫星上使用跟踪技术就相当的难，如果不在同步轨道上，两个方向都得跟踪就更难了。
天链不是北斗，北斗只能与地面之间通讯。
美国GPS是定位卫星，不算接受监控的话只能发信号，没有通讯功能。天链是星间通讯卫星，只管通讯好象不管定位，应该可以粗略地测出被通讯星的位置。
美国同类的不知道，至少在现在中国的技术比美国的还是要差，差多少也不知道，中国可以说还只是入门级。
卫星相撞的可能性当然是有的，美俄的卫星就相撞过，不过那好象是已经不受控的失效卫星。在用的卫星总是有点机动能力的，发射控制卫星的国家也会严密监视太空中的飞行物一，发现有相撞危险就会让卫星机动避开，好象是轨道相交距离在几十公里之内就可认为有相撞危险。但地面好象只能监测到几厘米以上的太空物体，小东西撞到要害一样会使卫星失效，这就很难预测，再加上卫星本身也可能会有非预测性失效，所以重要的卫星都会发一到几颗备用星在天上，一旦有显失效可以在最短时间补上。
不同的是地球同步通讯卫星两头对地，天链是一头对星一头对地或两头都对星，显然天链的天线指向范围要大得多。
中国航天<大腕>体 --- 不求认爹沾光但求尖端自主
今年土共发卫星像放二脚炮似的、没个消停、整个一土豪"立身"、这感觉真tm好、心花怒放!
