无线通信网络技术和全球卫星定位系统(GPS)技术是移动定位系统关键的两个要素。如今GPS接收机已经商品化,其体积可以做得很小,提供串口标准数据输出,数据接口很方便。而无线通信网络则多种多样,其建设成本、系统容量也各不相同,可供选择的通信网络有集群无线网、卫星数据通信网、移动通信网等等。在移动通信网中,GSM数字蜂窝移动通信网市场应用
Wireless communication network technology and global positioning system (GPS) technology are two of the key elements of mobile positioning systems. Today, GPS receivers have been commercialized, the volume can be done very small, to provide standard serial data output, data interface is very convenient. The wireless communication network is varied, its construction costs, system capacity varies, the choice of communication network cluster wireless network, satellite data communications network, mobile communications network and so on. In the mobile communication network, GSM digital cellular mobile communication network market applications
