Development of Seafloor Geodetic Observation System Based on AUV Technology

Institute of Industrial Science, University of Tokyo has started a project to develop new-generation seafloor geodetic observation system in cooperation with Hydrographic and Oceanographic Department, Japan Coast Guard. Central idea of this new system is to utilize techniques underwater robot and seafloor platform to take measurements in place of using a research vessel. Combination of these two techniques make it possible to conduct the observation with selecting favorable condition of sea and GPS satellite distributions, to make much more frequent observations and to enable flexible planning of observation in response to sudden geodetic events. Trial model of the newly developing system was finished. The repetition of trial and error has begun through a number of the field experiments in order to bring the system to completion.
