Abstract
This presentation covers the 10 year history of GGOS Japan. As many as six Japanese national institutes have been operating large-size geodetic facilities with VLBI and/or SLR in Japan and also in Antarctica, and they had been involved in each geodetic service rather independently. In 2013, we initiated "GGOS Working Group" in Japan to enhance the communications among the Japanese institutes and global geodesists and also to encourage collaboration beyond each technique. GGOS Japan is basically a loose network, but it has a chair, a secretary, an outreach representative, working groups (currently active: Data DOI working group) and representatives of each geodetic technique (VLBI, SLR/LLR, GNSS, DORIS and gravimetry). We regularly host annual meetings and sometimes small meetings with focused issues. We have also involved in organising or supporting scientific sessions in domestic and international conferences. During the 10 years history, it was positioned as a GGOS Affiliate in 2017 and we renamed it as "GGOS Japan" in 2019. Basara Miyahara was elected as the GGOS President in 2019. GGOS Japan's webpages are being updated on the GGOS Website, and we have contributed to GGOS YouTube channels. We often set focused activities. We are currently working on the review of ITRF2020 from an operating point of view, and we are also working on a possible best location for a future GGOS Cores site in Japan. In the future we hope to collaborate with international communities, in particular with other GGOS Affiliates.
