摘　　要：提出了一种基于几何精度因子(GDOP)的三维室内定位方案来解决室内定位系统中的锚节点布置问题.通过该方案可以得到锚节点的双圆锥构型.利用两种测距误差模型来对该方案的性能进行评估,仿真结果表明该方案可以应用于大小不同的场景,而且在相同的定位场景下,该方案的定位精度优于现有的布置方法.A geometric dilution of precision(GDOP)based 3D indoor positioning scheme was proposed for the layout of anchor nodes.Through the proposed scheme,the biconical configuration could be obtained.The performance of the scheme was evaluated by utilizing two different ranging error models.Simulation results indicated that the scheme can be applied to various scenes with different sizes.Furthermore,the proposed scheme had considerable accuracy improvement in the same positioning environment compared with existing layout scheme.
