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.

Space geodesy


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.

Earthquake &
Disaster prevention

Precise geodetic information was applied for not only geodesy and seismology but also various geoscieintific fields and disaster prevention fields. We promote appropriate earthquake disaster prevention and prediction research and application of our research to earth science.

Oceanography & others


A number of hidden information is sleeping in new sensors including GNSS-A. 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.
