The Hydrographic and Oceanographic Department, Japan Coast Guard (JHOD) installed an acoustic transducer on the bottoms of the S/V Meiyo (550 tons) in March 2008, the S/V Takuyo (2,400 tons) in February 2010, the S/V Kaiyo (550 tons) in March 2012, and the S/V Shoyo (3,000 tons) in November 2012 and started sailing GNSS-Acoustic (GNSS-A) observations. The JHOD also installed a seafloor geodetic observation system on the New S/V Heiyo (4,000 tons) in January 2020 for more efficient and precise seafloor positioning. In this report, we discuss the outline of the seafloor crustal movement observation system installed in the S/V Heiyo, the position measurement method and the measurement results of the GNSS antenna and the transducer, and the results of the test observationJournal
