SPACE GEODESY GROUP KOREA ASTRONOMY AND SPACE SCIENCE INSTITUTE
Korea Astronomy and Space Science institute (KASI) is the national astronomy and space science research institute of Korea established in 1974. KASI has wide variety of research areas like optical, radio, and theoretical astronomy and space science. Doing both pure scientific researches and developments of space-related techniques, KASI is leading the space science era of 21st century.
Space Geodesy Group of KASI focuses on Global Geodesy detecting the tiny variations of Earth’s shape and its rotation based on primary space geodetic techniques such as GNSS, VLBI, and SLR. Research field covers wide range of precise positioning from determination of reference frame and Earth rotation parameters to natural hazard monitoring. Space Geodesy Group has been operating the 1st International GNSS Service (IGS) Global Data Center (GDC) in Asia and Oceania region since 2006. KASI GDC archives the data directly from Asia and Oceania and hosts new regional IGS stations in this area as well as distributes all IGS data and products. We have also been operating KASI GNSS Network including 9 GNSS stations over Korea to provide high quality data in support of civilian and scientific applications. We are committed to many challenging research areas using GNSS data.
