基于北斗差分定位技术的车载终端研究

摘要

传统的北斗定位技术定位精度有限,只能满足一般的定位应用,因此为了适应一些高精度定位需求,比如驾校考试,精细农业等,基于北斗差分定位技术车载终端进行了研究.该研究以北斗差分定位技术为基础,以以太网的数据传输为条件,结合后台管理,进而实现了车载终端的厘米级定位,并对定位数据实时上传,最终后台通过对定位数据的分析,达到对车载终端位置的精确判别.%The positional accuracy of the traditional Beidou positioning technology is limited,it only can meet general positioning applications,so,for fitting some high-precision positioning requirements,such as driving exam,precision agriculture and so on,this article studies the terminal of vehicle which based on the Beidou differential positioning technology.This study is based on the Beidou differential positioning technology,conditioned by the data transmission of ethernet,combined with the background management,thus realized the cm-level positioning of terminal of vehicle,and the positioning data upload real-time.Finally,the background analyses the positioning data,and then reach the discriminant of the position of the terminal of vehicle.
