About

Ryosuke Yonezawa is a leading researcher in indoor localization and robotics navigation, with a focus on fusing GPS and pseudolite technologies to overcome the limitations of satellite-denied environments. His most cited work, "A combined approach of Doppler and carrier-based hyperbolic positioning with a multi-channel GPS-pseudolite for indoor localization of robots" (2016, 12 citations), introduces a novel method that integrates Doppler positioning with carrier-based hyperbolic positioning using a multi-channel GPS-pseudolite system. By leveraging precise carrier-phase observables from a GPS/pseudolite receiver, Yonezawa’s approach enables accurate indoor robot localization without relying on range information—a critical advancement for autonomous systems operating in warehouses, factories, or underground spaces. This work highlights his expertise in sensor fusion, signal processing, and real-time positioning. Yonezawa’s contributions are foundational for researchers and engineers developing robust navigation solutions for mobile robots in GPS-challenged environments, bridging the gap between theoretical positioning algorithms and practical deployment. His research continues to inspire innovations in indoor robotics and autonomous vehicle guidance.
