蓝牙在嵌入式车载导航定位系统中的应用

通过分析车载导航定位系统主流实现技术GPS＋DR组合定位技术所存在的问题，提出了路标传感器定位技术，它借助蓝牙短距离无线通讯技术实现车载系统及路标的通讯连接及数据传输；提出了系统整体实现方案，证明该定位系统具有实际的应用价值，可满足用户的需求，有一定的发展空间。

Application of Embedded Vehicle Navigation System Based on Bluetooth

Discussion on the issue of the major vehicle navigation system and a new approach to receive navigation data by beacon are presenred in this paper.The vehicle system can communicate with the beacon by Bluetooth module,which is a short-range module,what's more,we introduced the hardware and software of the whole system simply,proved this approach is useful in practice and meet with the needs of common user.
