We present a system for centimeter-precision 3 dimensional localization of a $2\times 3\times 0.3$ mm³, 5 mg, wireless system-on-chip by utilizing a temporally-structured infrared illumination scheme generated by a set of base stations. This 3D localization system builds on previous work by adding a second lighthouse station to enable 3D localization and using the integrated wireless radio, making the localization system fully wireless. We demonstrate 3D tracking with mean absolute errors of 1.54 cm, 1.50 cm, and 5.1 cm for the X, Y, and Z dimensions. This is the first time such a lighthouse localization system has been able to localize a monolithic single-chip wireless system. [2020-0102]

低功耗无晶体单芯片微尘的精确 3D 灯塔定位

我们提出了一个厘米精度的 3 维定位系统 $2\times 3\times 0.3$ mm ³ , 5 mg，无线片上系统，利用由一组基站生成的时间结构红外照明方案。这个 3D 定位系统建立在以前的工作基础上，通过添加第二个灯塔站来实现 3D 定位并使用集成无线电，使定位系统完全无线。我们展示了 3D 跟踪，X、Y 和 Z 维度的平均绝对误差为 1.54 厘米、1.50 厘米和 5.1 厘米。这是第一次这样的灯塔定位系统能够定位单片单芯片无线系统。[2020-0102]
