Radio Geodynamics
This section develops radio technology for the measurements of the Earth's rotation and its application to astrometry. It is also promoting the VERA (VLBI Exploration of Radio Astrometry) project by developing a new phase referencing VLBI technology. It conducts VLBI observations in millimeter wavelength region using the radio telescope.
Earth Rotation
This section studies the dynamical coupling processes among the Earth's atmosphere, ocean, crust, mantle, fluid outer core, and solid inner core from the Earth's dynamical behaviors such as the polar motion, length-of-day changes, precession and nutation.
Geodynamical Data
This section develops methods for time series analysis and information processing regarding geodynamical data, estimates the geodynamical and astronomical parameters based on VLBI and satellite observations, and operates international and domestic VLBI networks for establishing and maintaining the conventional terrestrial and celestial reference frames.
Earth Deformation
This section studies rheology of the Earth's mantle, dynamics of the core and effects of the core-mantle coupling by means of theoretical analyses of the tides and free oscillation of the Earth, and investigates the structures and dynamics of the planets by means of the tidal interactions with the Sun, the satellites and the other planets.
Gravity
This section investigates the Earth and planetary gravity fields and the motion of the Earth's interior by measuring the gravity changes, and contributes to international gravity standardization networks, and development of gravimetric techniques.
Precise Positioning (Visiting Researcher)
This section studies theories and technologies of precise positioning.
Geodynamics (Visiting Researcher)
This section studies Earth's dynamics and evolution from theoretical and technological aspects.
