Indoor positioning method based on space division using passive RFID
一种基于空间分割的无源RFID室内定位方法

In order to improve the performance of indoor positioning system,this paper proposed a positioning method using passive RFID.The algorithm improved the precision of indoor location by using two layers of symmetric distributed reference tags then conducting continuous space division.Measurements show that the algorithm can position the target in three-dimensional space in an acceptable range.Meanwhile,to compare the algorithm with the classic LANDMARC system,it improved the positioning precision by 8 times.So it is suitable for the application of indoor staff and goods positioning.
