美国GPS俄罗斯格洛纳斯与中国北斗卫星导航SG7050VAN爱普生差分晶振X1G004281000500
我们相信不久以后,北斗的陆基定位系统的基站数量一定会成倍增加,这样北斗定位系统的精准度就会大大提高,从而超过美国GPS定位系统和俄罗斯格洛纳斯定位系统在星基定位系统上北斗定位系统采用了三频信号,差分晶振精准度已经比美国GPS还要高,但陆基定位系统上美国基站的数量还是比中国要高出很多,所以在整体输出的精准度数值上,美国的GPS精准度比北斗定位系统还要高一些.三频信号制式最核心的优势就是让星基定位更精准,就说民用领域美国的GPS精准度只能做到6-8米,而中国的北斗定位精准度可以达到4-6米.有人会问为什么GPS有时还是更精准一些呢?

在这里简单的说明一下,完成一次定位需要星基定位系统和陆基定位系统共同协调,三频信号制式看似只是信号制式的改变,实质上通过三频信号制式的应用已经让北斗远远领先于GPS和格洛纳斯,目前GPS和格洛纳斯依然是采用的是双频信号制式(2018年开始,美国GPS也逐渐将信号制式进行高级别的优化和更新),爱普生晶振展望未来十年显然是北斗定位系统的优势窗口期.众所周知美国的GPS和俄罗斯的格洛纳斯定位导航系统发射、组网、应用比中国北斗定位导航系统起步较早,但他们都是以部署单一轨道卫星为基础技术背景,中国作为后起之秀吸纳了前辈们的不足之处,进行了全面升级和科技更新,最为独到的地方是北斗定位系统采用了三频信号制式.
