摘要
车载GPS利用GPS、计算机、现代通信以及自动化等现代高新技术来实现对车辆的实时监控和调度。其中,通讯手段的选择是车载GPS功能实现的关键技术。目前,常用的通讯方式有GSM/SMS、GPRS、CDMA。为此,将在介绍车载GPS的基础上,针对常用的通讯方式进行阐述和比较。
Vehicle borne GPS utilizes GPS , computer 、 modern communication . automation and other modern high technology to control and manage vehicle in real time, but how to choose the communication means is the key step. The present commonly used communication way is GSM/SMS, GPRS, CDMA, this paper will firstly introduce vehicle borne GPS, and then make comparing thoroughly to the commonly used communication way one by one.
