| 摘 要： | 针对,TI定位芯片CC2431在参考节点少于3个的情况下无法定位的问题,融合非测距定位的思想,提出了新的GIS辅助定位算法.结合该算法实现的ZigBee无线定位系统,可提供良好的定位性能.实验表明,当参考节点仅为两个时,仍能获得精确的定位;当参考节点少于1个时,可以得到区域估计信息.

| Abstract: | The location engine implemented in the CC2431 can not give a reliable result when there are less than three reference nodes.To solve this problem,we learn from the rang-free location algorithm,and put forward a new GIS assitant localization method.A Wireless Location System is created using this method with a good positioning performance.Experiments showed that when there are two reference nodes,accurate positioning performance can still beprovided.While there is no more than one,an area estimate can at lea... |
