在分析基于RSSI的LANDMARC定位系统及算法的基础上，提出了一种改进三角区域定位方法，消除了远距离不良参考标签对定位精度的影响。同时，在布置有大量阅读器的场合，该法可有效减少计算量。 Matlab仿真结果表明，该算法具有更高的定位精度。

This paper briefly introduced some common indoor positioning technologies and analyzed the LANDMARC system which is based on RSSI and its algorithm.On the basis of it, we proposed a triangle region po-sitioning method which can eliminate the bad influence on the positioning precision produced by the long-range ref-erence labels and effectively reduces the amount of computation when there are a large number of readers.The sim-ulation results obtained with MATLAB and their analysis show preliminarily that the algorithm proposed in this paper gives higher precision.
