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。
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 least be prolided.
