On the morning of March 14th, invited by SUN Heping, Academician of the Chinese Academy of Sciences. Harald Schuh, Professor of TU Berlin and Honorary Chairman of the International Association of Geodesy (IAG), visited the Innovation Academy for Precision Measurement Science and Technology (APM), Chinese Academy of Sciences(CAS), He delivered an academic report titled "Geodetic Research at GFZ Potsdam". The meeting was hosted by ZHANG Baocheng, a researcher at APM, and more than 20 scientific researchers and students from the State Key Laboratory of Geodesy and Earth’s Dynamics participated. Academician SUN Heping attended the meeting and unveiled the "International Science and Technology Cooperation Offshore Center for Geodesy Frontier Technology (Germany)" together with Professor Harald Schuh.
In his report, Professor Harald Schuh focused on the application of Global Navigation Satellite Systems (GNSS) in the field of earth science. Starting from the significance of studying natural disasters for the sustainable development of the earth, he systematically summarized the application of geodesy in the monitoring of natural disasters and climate change. Professor Harald Schuh first reviewed the development history of GNSS and introduced geodetic techniques such as Satellite Laser Ranging (SLR), Very Long Baseline Interferometry (VLBI), and Satellite Integrated Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS), as well as their applications in monitoring atmospheric precipitation, total electron content in the ionosphere, etc. He then further introduced the applications and missions of Earth observation satellites such as GOCE, GRACE, LAGEOS, and CHAMP in the remote sensing field, particularly mentioning the measurement achievements of the GRACE satellite in groundwater monitoring. Finally, he elaborated on the importance of Global Gravity Model of the Sea (GGMs), especially the role of the International Center for Global Earth Models (ICGEM) in practical applications such as geoid measurement.
After the meeting, Professor Harald Schuh, accompanied by ZHANG Jie, a young senior engineer, visited the National Geodetic Observatory station, Wuhan.
