About

Yasunobu Yagita is a researcher specializing in underwater robotics, seafloor geodetic observation, and acoustic communication systems. His work has focused on the development of innovative infrastructure for monitoring subduction zones and interplate earthquake regions in Japan, contributing meaningfully to marine geoscience and ocean engineering. Yagita's most significant contribution is his pioneering work on noncontact power supply systems for seafloor geodetic observing robot networks, explored across multiple publications between 2006 and 2008. His research helped lay the groundwork for autonomous underwater vehicle (AUV) docking stations connected to land facilities via submarine networks — systems designed to operate reliably in one of the most challenging environments on Earth. His most-cited paper on noncontact power supply (2007) has garnered 20 citations, while his 2006 companion study on high-speed acoustic networking has received 13 citations, reflecting steady engagement from the underwater robotics and geodesy communities. Further advancing the field, Yagita developed a prototype high-speed underwater acoustic network operating at 100 kbps using binary phase shift keying (BPSK) modulation. Though his citation counts are modest, his technical contributions represent foundational engineering work in seafloor observation infrastructure, with clear relevance to earthquake early warning and ocean floor monitoring research.
