它能让你的车载导航定位精度达到米级、轻松找到附近最美味的餐馆、甚至在没有信号的野外也能发短信,它正在给人们的生活带来越来越多的便利。这就是全球卫星导航系统,一双神奇的“眼睛”。目前,包括美国、俄罗斯、欧盟、中国在内的国家或地区都不惜投入巨资建设全球卫星导航系统,随着中国自主研发的北斗卫星导航系统去年底正式提供区域服务之后,全球卫星导航系统市场也从GPS一家独大迈入“四大天王”各领风骚的新时代。那么,全球四大卫星导航系统将各自扮演怎样的角色?
It allows you to navigate the positioning accuracy of rice meters, easily find the most delicious restaurants nearby, and even in the absence of the signal field can send text messages, it is to bring more and more conveniences to people’s lives. This is the global satellite navigation system, a pair of magical “eyes ”. At present, countries and regions including the United States, Russia, the European Union and China have invested heavily in building a global satellite navigation system. As China’s independently developed Beidou satellite navigation system officially provides regional services late last year, the global market for satellite navigation systems From the GPS into a single major “Four Kings ” each leading a new era. So, the world’s four major satellite navigation systems will play their respective roles?
