此文提出一种用射频标签RFID技术做定位以及导航的方法。使用标签反射能量（RSSI）来达到识别定位的目的。文章认为基站（阅读器）数目的增加，有利于定位精度的增加-An locating approach is proposed to find the location and tracking using RFID technique based on Received Signal Strength Indication (RSSI).It is found that the

利用 RSSI值对几何估算区域进行划分，运用改进公式计算出新的未知节点位置。(The geometric estimation area is divided by RSSI value, and the new unknown node position is calculated by the improved formula)
