[0031] 在本发明实施例中， 电子车牌贴附在车辆的某个位置， 例如， 挡风玻璃、 侧窗 玻璃或车门等位置， 本发明对电子车牌贴附在车辆的具体位置并不限制。
[0032] 需要说明的是， 电子车牌向至少三个基站发送的是超宽频脉冲信号， 其采用纳 秒级的非正弦波窄脉冲传输数据， 具有频带宽、 多频道、 低功耗、 不易干扰、 安全系数高， 能够与现有频谱共存 （即不会干扰现有及未来的超宽频通信应用 ) 等特点， 因此既可以通过对高速移动的电子车牌进行高精度定位， 进而对贴
附电子车牌的车辆进行高精度定位， 又可以增强定位的稳定性。
[0033] 另需说明的是， 在本发明实施例中， 至少三个基站互联且同步， 互联方法可以 采用有线网络互联或者无线网络互联， 其中， 无线网络包括 WiFi网络、 3G网络 、 4G网络和 5G网络中的一种， 所述定位算法包括达到吋间 TOA算法和达到吋间 差 TDOA算法中的一种。 至于基站之间的同步， 可以是至少三个基站中的任意一 个与定位服务器连接的基站向其他至少两个基站发送同步脉冲， 从而完成该基 站与其他至少两个基站之间的同步。
