Many nature phenomena around future megathrust earthquake source region on the undersea plate boundary. GNSS-A (combination technology of satellite positioning engineering and marine acoustics) unclosed highly precise behaviours after 2010. We now deeply research this sensor and its application and sophistication.
Sea surface platforms are important for underwater and seafloor observations such as GNSS-A. To solve this "sea surface platform problem," we are conducting research and development for the "third generation" sea surface platform next to ships and buoys. In recent years, we have been conducting technological research using "UXVs" including UAVs and USVs.
Satellite positioning, especially GNSS, had been researched for various applications after 1980s. Ocean and onland positioning and surveying technology and their data utilization systems are under development. We are advancing research for future position data utilization.
Precise geodetic information was applied for not only geodesy and seismology but also various geoscieintific fields and disaster prevention fields. We promote appropriate eddarthquake disaster prevention and prediction research and application of our research to earth science. Recent our research showed the possibility of GNSS-A oceanography corresponding to GNSS meteorology in GNSS. We promote interdisciplinary expansion and application of satellite observation engineering and marine sensor engineering.

"GGOS" is an international framework that contributes to the stable operation of space geodesy.
We are contributing to the "GGOS Japan" in Japan.
