Title of project : A geodetic VLBI system

I carried out a national research project of a geodetic VLBI (Very Long Baseline Interferometer) system for constructing a space geodetic observation center of NGII (the National Geographic Information Institute) in 2004~2011. And in March of 2012, the space geodetic observation center was established in Sejong-si.

Through the observed outcomes, the origin of the national geodetic system was determined based on the World Geodetic System (WGS). After that, in accordance with the trend that a new national geodetic system was introduced based on the WGS globally.
