The “Intelligent Integrated Positioning and Resilient PNT” Workshop was successfully held in Wuhan.

On April 24, 2026, the workshop titled “Intelligent Integrated Positioning and Resilient PNT”, organized by the State Key Laboratory of Precision Geodesy, was held in Room 206, Building 3, Geodesy Campus of the Innovation Academy for Precision Measurement Science and Technology, Chinese Academy of Sciences (CAS), Wuhan. The workshop was chaired by Prof. Jianghui Geng from the PRIDE research group. Academician Heping Sun of the Chinese Academy of Sciences was invited to deliver opening remarks and serve as the lead discussant.

Distinguished scholars invited to the workshop included Prof. Li-Ta Hsu (Department of Aeronautical and Aviation Engineering, The Hong Kong Polytechnic University), Prof. Fuqiang Gu (School of Computer Science, Chongqing University), Prof. Debao Wen (School of Geography and Remote Sensing, Guangzhou University), and Dr. Ding Yi (Associate Professor, School of Remote Sensing and Information Engineering, Sun Yat-sen University), who engaged in in-depth academic exchanges.

During the technical session, Prof. Li-Ta Hsu delivered a presentation entitled “Estimation in GNSS/INS Integrated Navigation: From EKE, FGO to SDP”, providing a comprehensive discussion on state estimation theories in multi-source integrated navigation and positioning.

Prof. Fuqiang Gu presented “Key Technologies for Intelligent Navigation in Complex Environments”, highlighting recent advances in high-precision autonomous positioning, real-time onboard perception, online planning, and safety-critical control.

Prof. Debao Wen delivered “The Mathematical Elegance and Physical Interpretation of Ionospheric Tomography”, offering insights into the physical mechanisms and current challenges in ionospheric modeling.

Dr. Ding Yi presented “Performance Evaluation and Application of Galileo HAS in Low-Cost Receivers and Smartphones”, focusing on GNSS data processing for low-cost mobile platforms.

Prof. Jianghui Geng also reported key outcomes of the National Key R&D Program project titled “Componentized Flexible Integrated Navigation and Control Key Technology and Application Verification.”

Academician Heping Sun provided detailed comments on the presentations and engaged in extensive discussions with participants. The workshop fostered active exchanges on fundamental scientific problems and technical challenges in multi-source integrated positioning.

The afternoon session was chaired by Associate Researcher Guangcai Li of the PRIDE research group. Dr. Shiyu Bai (The Hong Kong Polytechnic University) delivered a presentation entitled “AI-driven Proprioceptive Navigation”. Dr. Ding Wang (Innovation Academy for Precision Measurement Science and Technology, Chinese Academy of Sciences) presented “Multi-source Integrated Simultaneous Localization and Mapping Based on Panoramic Ring Cameras”. Dr. Penggao Yan (The Hong Kong Polytechnic University) gave a talk titled “Statistically Informed Huber Tuning for Robust Urban GNSS Positioning”. Zixuan Wang (Ph.D. student, Wuhan University) presented “Active Fault Detection and Identification Methods for Low-Redundancy Resilient PNT”. Dr. Penghui Xu (The Hong Kong Polytechnic University) delivered a presentation on “Applications of Artificial Intelligence in Satellite Navigation”. Long Zhao (Master’s student, Wuhan University) presented “Wideband Tracking and Instantaneous Decimeter-Level Positioning of Subcarrier Signals Based on Full-Component Joint Processing”. These presentations covered topics including pedestrian dead reckoning, panoramic camera-based SLAM, resilient PNT, and AI for satellite navigation, demonstrating the innovation and vitality of early-career researchers in this field.

During the laboratory visit, Prof. Jianghui Geng introduced the componentized PNT hardware platform developed for the National Key Research and Development Program Project. Participants also visited the NOKOV indoor ground-truth positioning system and observed a live demonstration using a quadruped robotic platform.

Finally, all participants gathered for a group photo.
