International academic exchanges on Geodetic GNSS precise positioning and organized ionospheric research----Institute of Geodesy and Geophysics, Chinese Academy of Sciences

Invited by National Key Laboratory of Geodesy and Geodynamics, Chinese Academy of Sciences, Professor Peter Teunissen from Australia Curtin University and Royal Netherlands Academy of Sciences, Dr. Sandra Verhagen from The Netherlands Delft University of Technology University, Professor Liu Shuoan who is Taiwan's "National Central University" Distinguished Professor and also the foreign academician of the Russian Federation of Engineering Sciences, Professor Kefei Zhang from Australia RMIT University, professor Andrzej Krankowski from University of Warmia and Mazury of Porland who is also the Chair of IGS ionosphere working Group, and Professor Manuel Hernandez -Pajares Universitat Politecnica de Catalunya University of Spain who is the last chair of IGS ionosphere working group , visited to the Institute of Geodesy and Geophysics on May 13th and 14th, and made academic reports on the latest advances and the developing trends of GNSS precise positioning and ionospheric research . The conference was hosted by researcher Yuan Yunbin, deputy chair of State Key Laboratory of Geodesy and Geodynamics.

During the meeting, experts, scholars and researchers from home and abroad thematically discussed the hot issues of the latest international research findings, such as the GNSS ambiguity fixing and its precision applications, GNSS ground-based observing technology and its applications on weather forecasting, GNSS radio occultation technique, GNSS ionospheric sounding technique and its impact on the precision positioning, new progress of IGS ionosphere monitoring technology and new products and services and so on. Furthermore, they also carried out a special report to discuss hot issues and key technological difficulties and their future direction .

By organizing exchange report,it is not only presented the progress of GNSS geodetic precision positioning and ionospheric research to the international peer scholars , and also expands the Institute's young researchers’ perspective to promote carrying out follow-up relevant international cooperative research. In addition, it provides a good learning opportunity for graduate students of the institutes.
