About
Kenjiro Fujii is a leading researcher in indoor localization and mobile robot navigation, specializing in high-accuracy positioning systems that overcome the limitations of GPS in enclosed environments. His major contributions center on the development of carrier-phase and Doppler-based methods using pseudolites and the Indoor Messaging System (IMES), achieving centimeter- to decimeter-level accuracy where conventional radio-based technologies fail. Fujii pioneered the "real-time kinematic (RTK) Doppler pose estimation" technique, which harnesses Doppler shifts from IMES transmitters to deliver precise pose estimates, and combined Doppler positioning with carrier-based hyperbolic positioning for multi-channel GPS-pseudolite systems. His work addresses critical challenges such as cycle slip in carrier-phase tracking and integrates dead reckoning to improve IMES accuracy. With his most cited paper garnering 12 citations and a cumulative impact across several influential studies, Fujii has advanced active-localization methods for mobile robots, including rhythm-based adaptive localization with floor-embedded RFID tags. His research is essential reading for engineers and roboticists seeking robust, high-precision indoor navigation solutions.
