对中国北斗卫星的认识？英文双语对照

国产的卫星网北斗已经全部发射组建网络有一段时间了，但是很多人还是不太明白这为我们的生活带来了什么样的改变，很多人对北斗网络还是没有太多了解，今天就为大家好好科普一下这个我们的国产卫星网络。

北斗网络是国产全球卫星定位系统，原理是利用太空中的卫星进行定位，只要在空中有四颗及以上卫星，就可以达到精准定位。而随着最后一颗北斗卫星是升空，整个北斗系统已经组成了一个覆盖全球的网络，无论是在什么地方都可以使用北斗系统进行智能电子产品的定位。

首先，为什么要组建北斗网络

今年的6月23日上午，北斗网络完成，最后一颗北斗卫星发射成功。北斗网络是作用于卫星精确定位领域，中国组建北斗网络的目的就是为了要自己的卫星定位系统，摆脱美国GPS的限制。卫星定位系统领域小到个人的地图寻找，大就到了整个国家安全层面了，所以这个领域必须要我们自主可控。

很长一段时间GPS完全掌握在美国的手里，但是这个技术关系重大，所以很多国家都大力发展中国领域，俄罗斯发射了格洛纳斯，欧盟有伽利略卫星定位系统，中国也早在2000年就建成了北斗的导航试验系统，经过20年的发展北斗系统终于建成。

然后，北斗网络能干什么

北斗网络的本质就是卫星定位系统，这个领域最早最知名的系统是美国的GPS，GPS其实就是全球定位系统的简称。说到GPS，大家就比较熟悉了，我们使用的电子设备经常就需要使用，尤其是使用一些地图APP的时候。而北斗卫星系统能干的事和GPS是一样的。

而且不止如此，在国家层面北斗系统能做的事情更多。在渔业、测绘、水利、电信、交通运输等领域都有广泛的应用，尤其是在森林防火、减灾救灾等涉及到公共安全的领域，作用更是极大。在08年的汶川地震的时候，当时还在试验中的北斗系统就发挥了巨大的作用，让救灾更明了更有效。

最后，北斗网络会为我们带来什么改变

这个改变主要是在国家的层面意义重大，把一个非常重要的握在了自己的手里，不会陷于被动。不过对于普通人来说，也能为我们的生活提供更多便利。其实在我们不知不觉里，我们已经用了很多次的北斗系统了。市面超过70%的智能手机已经可以支持北斗定位系统。

只是因为GPS就是全球定位系统的简称，所以很多人以为用的还是美国的系统，但是实际上GPS是这个功能的名字，而且手机是会自动使用信号最好的定位系统的，所以在不知不觉里我们可能用了北斗，用了欧洲的伽利略或者俄罗斯的格洛纳斯。对我们来说多了一套完整的卫星系统，能让我们在使用时更加稳定。

North fights homebred satellitic network to had blasted off entirely establish a network to have period of time, but a lot of people or the life that understand this is us not quite brought what kind of change, a lot of people fight a network to north or do not have too much understanding, it is everybody today well popular science this next one our homebred satellite networks.

North fights a network is system of location of satellite of homebred whole world, the principle is to use the satellite in aerospace to have fixed position, want to there are 4 to reach above satellite in sky only, can achieve essence of life to follow fixed position. And fighting a satellite as last north is to enter the space, whole north fought a system to had formed a network that covers the whole world, no matter be,can use north to fight a system to have the fixed position of intelligent electron product in where.

Above all, why to want to establish north to fight a network

This year on June 23 morning, north fights a network to finish, last north fights a satellite to launch a success. North fights a network is action Yu Weixing exact location domain, the goal that China establishs north to fight a network is to want his satellitic location system, cast off the limitation of American GPS. Domain of satellitic location system is small search to the individual's map, arrived greatly level of whole country security, so this domain must want us to be able to accuse independently.

GPS of very long period of time masters completely in American hand, but this technology count for much, so a lot of countries develop Chinese field energetically, russia launched Geluonasi, the European Union has system of Galilean satellite location, china built the navigation test system that north fights early also 2000, through development of 20 years north fights a system to build eventually.

Next, north fights a network able what

The essence that north fights a network is satellitic location system, this domain is the earliest the GPS that the famousest system is the United States, GPS is the abbreviation of global location system actually. Respecting GPS, everybody was familiar with quite, the electronic device that we use often needs to use, when using APP of a few maps especially. And it is same that north fights the thing with satellitic efficient system and GPS.

And more than and such, the its more that the system can do is fought in national level north. Carry in fishery, mapping, irrigation works, telegraphic, traffic wait for a domain to have wide application, be in especially silvan fire prevention, decrease calamity to provide disaster relief wait for the field that involves public safety, effect is more great. The short of Wenshui River in 8 years plain earthquake when, the north in still experimenting at that time fought a system to produce tremendous effect, let provide disaster relief clearer more effective.

Finally, north fights a network to be able to bring what change for us

This change basically is the level meaning in the country great, very important grasp was in in oneself hand, won't sink is passive. Nevertheless to Everyman, the life that also can be us offers more advantage. Be in actually we are imperceptible in, the north that we had used a lot of times fights a system. Market exceeds the smartphone of 70% to be able to have supported north to fight location system.

Because GPS is the abbreviation of global location system,be only, so a lot of people think those who use still is American system, but the name that actually GPS is this function, and the mobile phone is the location system with can automatic use first-rate signal, be in so imperceptible in we may use north to fight, the Galileo that used Europe or the Geluonasi of Russia. much to us a whole satellitic system, can make us more stable when use.
