Welcome to the web pages of Space Geodetic Observation Center(SGOC).
SGOC is the 16th geodetic VLBI observatory in the world and the 3rd in Asia, and
the pioneer of the new era of space geodetic survey in South Korea.
Colocation, so-called local ties, determines the relative positions by the measurement of distance and reference points and calculates tie vectors between each sites.
The local tie vectors between different geodesy instruments in co-located sites are essential for the construction of ITRF(International Terrestrial Reference Frame).
