The GGFC SBH had been hosted by the Center for Space Research (CSR) at the University of Texas at Austin (UT) since its inauguration in 1998. Prof. Chen (chairing the GGFC SBH since 2004) has recently joined the Department of Land Surveying and Geo-Informatics (LSGI) at the Hong Kong Polytechnic University (PolyU), after spending 28 years of his academic career at UT CSR. After discussions with the GGFC chair (Dr. Jean-Paul Boy) and IERS, we have decided to move the hosting institute to PolyU to ensure a continuous service to the community.
