Radio Science
The 35th URSI General Assembly and Scientific Symposium (URSI GASS 2023)
Venue: Sapporo Convention Center
Delegates: 1,434 from 49 countries/regions
Organized by the International Union of Radio Science (URSI), the URSI General Assembly and Scientific Symposium (URSI GASS) is an international conference that has been held once every three years since 1919. The development of radio science plays an extremely important role in supporting today’s ICT society, as well as monitoring of global environment and management of natural disaster risks. This was the third URSI GASS held in Japan, first held in Tokyo in 1963 and then Kyoto in 1993. Under the theme “the future opened up by radio science toward a sustainable society”, various cutting-edge research results were presented and discussed by scientists and engineers from around the world. The congress is expected to contribute to the development of future generation of researchers, as well as the advancement of the radio science activities in Asia Pacific.
_Technical Tour
The Super Dual Auroral Radar Network (SuperDARN) has over 35 radar sites at middle to high latitude areas in both northern and southern hemispheres of the earth. Sapporo Convention Bureau supported the organization of the post-conference technical visit to one of these radars located in Rikubetsu Town in the eastern part of Hokkaido (also known to be the coldest town in Japan). During the two-night tour, delegates visited the Rikubetsu Space and Earth Science Museum (Galaxy Forest Observatory) and the SuperDARN Hokkaido HF Radar in Rikubetsu, with the latter accompanied by Associate Professor Nozomu Nishitani, who leads the SuperDARN project at the Institute for Space-Earth Environmental Research at Nagoya University.
_Public Event “Experience the Invisible Radio Waves”
On the last day of the conference, a science workshop on how radio science technologies are utilized in everyday life was organized for elementary school students (and their parents) in Sapporo and Rikubetsu Town. Supported by the students from Hokkaido Information University, children made a germanium radio, which does not require batteries, and their parents made a large receiver antenna – quite tricky but a useful device that could be helpful at the time of power outages or natural disasters with disrupted communication. The workshop was followed by an online networking session between Sapporo and Rikubetsu and a science show organized by the Sapporo Science Center.
