Single Anchor-Based Infrastructure-less Localization Performance using UWB Radios

The paper discusses single anchor-based solutions for providing infrastructure-less localization using Ultra Wide Band (UWB) radios. The localization solution proposed in this paper comprises of two essential components: a fixed anchor node, which serves as the base station, and one or more mobile tags. The anchor and the tags are equipped with two UWB modules in orthogonal directions - with this setup, the proposed solution is capable of accurately measuring the distance and the angles between the anchor and the tags in a 3D plane. Through extensive experimentation, we show that the proposed solution achieves a ranging error well below 1 m, whereas the angle measurement errors lie below 10 degrees.
