[SGD02-02] Framework to connect Global Geodetic Community to Japan -GGOS Japan-
Keywords:Global Geodetic Observaing System, GGOS, Space Geodetic Techniques, Geodesy Outreach
The Global Geodetic Observing System (GGOS) is a collaborative contribution of the global Geodesy community to the observation and monitoring of the Earth System. In order to serve as the primary place of advocacy and enhancement of geodetic observations and products which are the key enablers for geodesy to deliver its values to science and society, GGOS has been closely working with stakeholders within and outside of geodesy. One of the roles of GGOS is to facilitate collaboration among those stakeholders. GGOS Affiliate is a component of GGOS to enhance the collaboration and communication within stakeholders in a country or region, and GGOS Japan is the first GGOS Affiliate which was established in 2013 as “GGOS Working Group” in order to facilitate geodetic collaboration in Japan. This presentation highlights the recent activities 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 institute 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 Marine Geodesy 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 organizing or supporting scientific sessions in domestic and international conferences and hosted international meetings in Japan such as the 18th International Workshop on Laser Ranging in 2013 and the 13th IVS General Meeting in 2024. The next opportunity could be the IGS Workshop 2028.
One of the most important roles of GGOS Japan is outreach to raise awareness for the value of geodesy as the underpinning infrastructure for science and society. GGOS Japan's webpages are being updated on the GGOS Website (https://ggos.org/), and we have contributed to geodesy outreach of global GGOS by creating a short video on a local tie campaign topic and also a Japanese voice-over version of "Discover GGOS and Geodesy" and “Terrestrial Reference Frames - Connecting the World through Geodesy” on GGOS YouTube channel (https://www.youtube.com/@iag-ggos).
We often set focused activities. DOIs for geodetic data set are one of our focus and we invited the chair of GGOS DOIs committee, Kersten Elger to a workshop on this topic in NPRI on March 2024 in order to discuss sustainable ways how to assign DOIs to geodetic data in Japan. The GGOS DOIs committee published recommendations to the optimal ways to mint DOIs to GNSS related datasets, and GGOS Japan held a meeting to discuss the best way to mint DOIs for GSI’s GEONET dataset on February 2025.
Marine Geodesy is one of the hot and urgent topics in the IAG, and GGOS Japan also established a new working group on Marine Geodesy. One of the activities of this working group is joint presentation at the UN-GGCE Land-Sea Integration in December 2024 in Indonesia which was prepared jointly by the GSI and Hydrographic Department of Japan Coast Guard, Other possible new activities of GGOS Japan are contribution to the GENESIS satellite mission by ESA for space collocation of geodetic techniques or planetary geodesy, and we will continue to seek and discuss new topics to connect domestic and global geodetic communities.
We hope to extend these collaborations to wider scientific communities in Japan and further collaborate with international geodetic communities, in particular other GGOS Affiliates.
