To tackle challenges such as interference and poor accuracy of indoor positioning systems, a novel scheme based on ultra-wide bandwidth (UWB) technology is proposed. First, we illustrate a distance measuring method between two UWB devices. Then, a Taylor series expansion algorithm is developed to detect coordinates of the mobile node using the location of anchor nodes and the distance between them. Simulation results show that the observation error under our strategy is within 15 cm, which is superior to existing algorithms. The final experimental data in the hardware system mainly composed of STM32 and DW1000 also confirms the performance of the proposed scheme.

基于超宽带的新型室内定位系统

为了解决诸如室内定位系统的干扰和精度差的挑战，提出了一种基于超宽带（UWB）技术的新颖方案。首先，我们说明两个UWB设备之间的距离测量方法。然后，开发了泰勒级数展开算法，以使用锚节点的位置及其之间的距离来检测移动节点的坐标。仿真结果表明，我们的策略下的观测误差在15 cm以内，优于现有算法。在主要由STM32和DW1000组成的硬件系统中的最终实验数据也证实了该方案的性能。
