OpenRSSI: Zero-Drift Motion Capture Using Consumer-Grade UWB Hardware

This paper presents OpenRSSI, a novel motion capture system that leverages ultra-wideband (UWB) radio signal strength indicators combined with inertial measurement units (IMUs) to achieve high-precision tracking without the positional drift common in pure inertial systems. Our approach utilizes an adaptive sensor fusion algorithm that dynamically adjusts to environmental conditions and movement patterns, providing robust tracking across varied use cases.
