URSI GASS
The URSI General Assembly and Scientific Symposium (URSI GASS), formerly called URSI General Assembly (URSI GA), is a top-tier international conference held every three years since 1919 and is organized by the International Union of Radio Science (URSI)
It aims to review current research trends, present new results and discoveries, and make plans for the future research and special projects in all areas of radio science, especially where international cooperation is desirable. The URSI GA has been held twice in Japan: The first was the 14th GA held in Tokyo in 1963 and the second was the 24th GA held in Kyoto in 1993, both of which led to a great success. The URSI GASS 2023, the third one in Japan, is planned to be held in Sapporo, Japan during August 19–26, 2023. The conference is expected to attract more than 1,200 radio scientists and engineers from around the world (500 domestic and 700 international).
