On the morning of August 20, 2025, the "High-Precision GNSS and Surface Deformation Monitoring Seminar" hosted by the Innovation Academy for Precision Measurement Science and Technology, Chinese Academy of Sciences was successfully held in Conference Room 206, Building 3, Donghu Campus. The seminar was chaired by Researcher Geng Jianghui.

At the beginning of the conference, Researcher Geng Jianghui delivered a welcome speech, extending a warm welcome to all the experts and scholars present. This kicked off the seminar and created a favorable atmosphere for communication.

First of all, Researcher Wen Qiang presented a report titled "PRIDE PPP-AR and Its High-Precision Geoscientific Applications". Researcher Wen Qiang introduced in detail the principle, characteristics of the PRIDE PPP-AR technology and its application cases in the high-precision geoscience field. He demonstrated the significant advantages of this technology in improving the accuracy of geoscience research, providing new ideas for geoscience workers and sparking extensive thinking among participants about how high-precision positioning technology can serve geoscience research.

Subsequently, Researcher Liu Shaozhuo gave a report entitled "The Current Uplift of the East Kunlun Mountains Driven by Lower Crustal Thickening". Researcher Liu Shaozhuo deeply analyzed the dynamic mechanism of lower crustal thickening and how this thickening process drives the current uplift movement of the East Kunlun Mountains. Through multi-dimensional analyses of crustal structure and material migration, and verification with GNSS monitoring data, he clearly presented the internal relationship between tectonic movement and surface deformation, providing theoretical and data support for understanding the evolution of orogenic belts and the background of regional geological disaster incubation, and offering a new perspective for understanding the geological evolution of this region.

After that, Researcher Zheng Gang brought a report titled "Discussion on the Applicability of Block Movement Models at Kilometer-Level Resolution——A Case Study of the Qinghai-Tibet Plateau". From the analysis of model assumptions to the fitting degree in actual geological scenarios, he explored the advantages and limitations of the model in explaining geological processes such as plate collisions and block extrusion deformation, providing practical references for optimizing block movement models and improving the accuracy of geological process analysis.

During the discussion session, the atmosphere was warm and practical. e participating experts and scholars launched interdisciplinary and in-depth exchanges around the report content. There were not only candid discussions on the bottlenecks of technology application, but also active suggestions on innovative research directions. Different viewpoints collided, broadening the ideas for subsequent scientific research cooperation and technological breakthroughs.

The successful holding of this seminar not only promoted academic exchanges in the field of surface deformation monitoring using high-precision GNSS technology, but also provided a valuable learning and communication platform for scientific researchers in related fields. The participants unanimously stated that through this seminar, they had a deeper understanding of high-precision GNSS technology and its applications in surface deformation monitoring, which is of great guiding significance for their future research work.
