话说Stay hungry，Stay foolish 和 北斗导航那点事
今天在路上时，突然想起乔帮主Jobs生前讲过的那句名言：Stay hungry，Stay foolish.以前觉得这句话的意思，无非是要人们保持一种对事物的求知若渴的态度，但今天突然觉得乔帮主的完整意思应该是，既要保持对周围事物的求知若渴态度，也要清醒地认识到自己的愚蠢。前者好理解，保持对周围事物，尤其是新生事物的好奇心和强烈学习感，但为什么我要说保持一颗认为自己还很愚蠢的心呢？那是因为，人都有自满的时候，很多时候，我们往往容易心生自满，甚至自以为是，或者片面地依据经验认为足够优秀等，而这个时候如果有新的东东出现时，我们却容易不屑一顾，甚至排斥，也正是这样愚蠢的自满想法，很多时候会让我们白白失去很多机会。所以我认为乔帮主这句话的本意应该是，希望保持一颗求知若渴的心，同样也要认识到自己的愚蠢而不至于自满从而丧失机会。
下午从外地刚出发时没多久，悲催地发现手机没电了，要知道我出门都是很依赖手机导航的，这一下子失去导航，突然感觉很不适应，一下子是点乱了阵脚。夜晚高速路上多数漆黑一片，公路两旁在大灯的照射下暗弱的反光还可以看到，每到临近指示牌的时候，不免要瞪大了眼睛看上边的路线指示，这对于我这个近视眼来说，不能不说是个不小的考验。囧
好在一路还较为顺利，临近市区还有二三十公里的时候，两旁的灯光顿时璀璨起来，远处已经可见城市夜晚漂亮的轮廓了。
看来这出门，导航还真是离不开。想到上个世纪台海危机时，我们那时候的设备都是依赖GPS导航，但在关键时刻，老米关掉了部分区域的GPRS信号，直接导致了我们的军舰和制导武器等秒变成瞎子，这之后，我国终于下定决心要开发自己的卫星导航系统，也就是现在我们所熟知的北斗导航系统。
说起北斗导航的研发，还有段有趣的故事。我们知道，目前世界上包括美国的GPS、欧洲的伽利略（Galileo）、俄罗斯的格洛纳斯卫星导航系统（GLONASS）、以及我国自主研发的北斗系统。早期开始研发北斗系统的时候，我们原本也寄希望于能一同参与欧洲的伽利略系统的研发，但欧洲却做出一件非常过分的事情，只接受中国资金，不让中国参与核心技术研发，研发成功后，中国购买，又拒绝出售伽利略的核心技术，这当然让人无法接受的。
无奈之下，我国便加快了自主的北斗系统研发，正式宣布北斗二号导航系统频段采用与欧洲伽利略卫星一样的PRS频段。而卫星通信频道是以谁先占谁有理原则，先占先得原则是西方发达国家制定的，这又让欧洲叫苦不迭，但最令人难堪的是，直到我国的北斗已经研发成功并正式军用和商用了，欧洲还在会上为伽利略导航的一些内容讨论喋喋不休。。。至于正式使用？鬼才知道什么时候能用了。。。

English Version Of This Awesome Article By Teacher @rivalhw!
Say something about Stay hungry, Stay foolish, and Beidou navigation!
When I was on the road today, I suddenly remembered the famous quote Joe had made during his lifetime: Stay hungry, Stay foolish. What I used to think about this sentence is to ask people to maintain a thirsty attitude towards things, but today Suddenly I feel that the full meaning of Joe's lord should be to maintain his thirst for knowledge of the surrounding things, but also to clearly recognize his stupidity. The former is well-understood and maintains curiosity and a strong sense of learning about the surrounding things, especially new things. But why should I say to maintain a heart that thinks I am still stupid? That's because when people are complacent, many times, we tend to be complacent and even self-righteous, or we think that one-sided experience based on experience is good enough. When this occurs, if new stuff appears, we will easily disdain it. It is such stupid complacency thoughts that one can even consider and even reject. In many cases, we will lose many opportunities in vain. Therefore, I think that the intention of Joe Benjamin’s phrase should be to maintain a thirsty heart, but also to recognize his stupidity and not be complacent and lose his chance.
In the afternoon, just after setting off from the field, I was sadly reminded that the mobile phone was dead. I knew that I was relying on mobile navigation to go out. This lost my navigation and I suddenly felt very uncomfortable. All of a sudden it was a disarray. At night, most highways are dark, and the faint reflections on both sides of the highway under the illumination of the headlights can be seen. When approaching the signage, they must inevitably have their eyes widened to see the directions of the road. This is for my short sightedness. It cannot be said that it is not a small test. Oops
It was still relatively smooth along the way. When there are twenty or thirty kilometers in the vicinity of the city, the lights on both sides are suddenly picked up. The distant outline of the city can be seen in the distance.
It seems that this is going out and navigation is really inseparable. When we thought of the Taiwan Strait crisis of the last century, our equipment at that time relied on GPS navigation, but at a crucial moment, Laomi turned off some areas of GPRS signals, which directly caused our warships and guided weapons to become blind. After that, China finally decided to develop its own satellite navigation system, which is now known as the Beidou navigation system.
Speaking of the development of Beidou navigation, there are interesting stories. We know that currently the world includes GPS in the United States, Galileo in Europe, GLONASS in Russia, and the Beidou system independently developed in China. When we started to develop the Beidou system in the early days, we originally hoped to participate in the research and development of the Galileo system in Europe. However, Europe has done a very sizable job, accepting only Chinese funds and preventing China from participating in core technology research and development. After the success, China purchased and refused to sell Galileo's core technology. This is certainly unacceptable.
In desperation, China accelerated the development of the autonomous Beidou system and formally announced that Beidou-2 navigation system uses the same PRS frequency band as the European Galileo satellite. The satellite communication channel is based on who has the principle of first and foremost. The principle of first-come first-servance was set by Western developed countries. This in turn made Europe agonizing, but the most embarrassing is that until our country, Beidou has been successfully developed and officially used in military and commercial applications. At the meeting, Europe also discussed chatter about Galileo's navigation. . . As for the official use? The ghost only knows when he can use it.
Indeed a great post, and we have lots of things to think. Thanks @rivalhw for always giving us such interesting and useful stuff by spending your quality time for us steemians. Keep it up and always Stay Blessed!

我去哪都得用导航，(^▽^)，还得带着充电宝，怕手机没电。
大伟哥，打扰了。
