| Research Abstract |
We have developed a new-generation observation system for seafloor geodesy. This system utilizes autonomous underwater vehicle, seafloor platform and submarine cable technologies, and it provides opportunities for highly efficient geodetic observations with improved accuracy. Key constitutive technologies for the system have been developed successfully, and we integrated the technologies to construct an observation system. A seafloor acoustic benchmark station with a submarine cable transponder was constructed 70km off Toyohashi-city as a prototype of the newly developed system. Trial observation using this submarine cable transponder and a semi-autonomous observation platform revealed that the system were at the level of practical use.
