Mizusawa VLBI Observatory, National Astronomical Observatory of Japan, is
operating many geodetic observation systems such VLBI, GNSS and gravimeters.
For the VLBI observation, we commenced constructing VERA (VLBI Exploration of
Radio Astrometry) in 2000. VERA consists of four VLBI stations and each station has
a 20m antenna. We started regular geodetic VLBI observations with VERA in 2004.
One of VERA stations joins in IVST2 and AOV networks at present. For the GNSS
observations, we are operating GPS observations at VERA stations. Also, we are
operating an IGS station and a GESS (Galileo Experimental Sensor Station) in the
Mizusawa campus in cooperation with GFZ Potsdam. For the gravity observation, we
had been operating gravity change observation with a superconducting gravimeter at
Esashi Earth Tides Station for the year 1988-2008, and have been operating similar
observation at Mizusawa since 2009 until now. In the Mizusawa campus, all of these
facilities are located within 250m area and collocated observations are performed.
We introduce those geodetic observations systems in Mizusawa VLBI Observatory.
Besides we introduce several observation results including those at the Tohoku
Earthquake in 2011 obtained with the different techniques.
