Advancements in Precise Positioning and Geoinformation Science

Advances in precise positioning technology have revolutionized fields such as satellite navigation, scientific research, and economic development. Precise positioning technology has become indispensable for determining spatiotemporal information and providing navigation services. The latest technology has achieved centimeter-level positioning accuracy, enabling real-time seismic monitoring and monitoring of the Earth system. However, there is still a need for further refining environmental load modeling methods and establishing surface mass distribution models with high spatiotemporal resolution. Scientists have made significant progress in applying environmental loading to address nonlinear motion in global and regional satellite navigation reference stations. Hyperspectral imaging has also made significant contributions to acquiring geographic information, particularly in areas such as ecological environment monitoring, mineral resource investigation, and land planning. In addition, innovations in remote sensing and satellite navigation have made remarkable advancements, profoundly changing people's lives and work.
