On July 12, the inter-project exchange meeting of the National Key R&D Program “Earth Observation and Navigation” was successfully held at Harbin Engineering University. The meeting was hosted by the School of Future Technology at Harbin Engineering University, aiming to strengthen collaboration among projects and promote joint efforts in tackling key technologies and advancing scientific cooperation. Attendees included the project team led by Prof. Yonggang Zhang from Harbin Engineering University, responsible for the project “High-Precision Miniature Optical Gyroscope Inertial Navigation System and Application Verification”, and the project team led by Prof. Jianghui Geng from Wuhan University, responsible for the project “Key Technologies and Application Verification of Componentized Integrated Navigation and Control”. The meeting was chaired by Prof. Yonggang Zhang.

At the beginning of the meeting, Prof. Yonggang Zhang delivered a welcome speech and warmly welcomed Prof. Jianghui Geng and his team. Profs. Zhang and Geng then introduced the fundamental information and current progress of their respective projects, showcasing phased achievements and research highlights.

During the technical exchange session, members from both project teams presented and discussed key research outcomes under the National Key R&D Program. Prof. Zhiqiang Miao from Hunan University gave a talk titled “Empowering the Low-Altitude Economy with UAVs: From Land-Air Amphibious UAVs to UAV Swarms”, systematically introducing the design schemes of land-air amphibious UAVs and key technological advances in cooperative path planning and control for UAV swarms.

Prof. Pai Wang from Wuhan University presented a report titled “Fisheye Camera-Enhanced Environmental Perception for High-Precision GNSS/INS Integration”, sharing the team’s latest research outcomes in multi-sensor cooperative perception and high-precision fusion positioning. The presentation emphasized the performance enhancement brought by fisheye camera/INS integration for GNSS positioning in complex environments.

Prof. Menghua Zhang from Nanjing University delivered a report on “Microcavity Brillouin-Kerr Soliton Frequency Comb Generation and Its Application in Low-Noise Microwave Sources”, offering detailed insights into the fabrication processes of frequency comb samples, the generation mechanisms of Brillouin-Kerr solitons, and their promising applications in advanced microwave sources.

Prof. Maoran Zhu from Shanghai Jiao Tong University presented research findings under the title “Multi-Source PNT Fusion Based on Continuous/Discrete Optimization”, demonstrating the method’s effectiveness and robustness in inertial/magnetometer and inertial/vision-based pose estimation.

Prof. Liu Yang from Harbin Engineering University gave a talk on “High-Precision Miniature Resonant Optical Gyroscopes”, introducing the latest breakthroughs and achievements of the research team in miniaturization and integration of optical gyroscope development.

Prof. Shi Hang from ZheJiang Lab gave a presentation titled “Heterogeneous Intelligent Computing Platforms for Navigation”, showcasing a heterogeneous computing architecture composed of a PNT platform prototype, domestically developed intelligent computing boards, and sensor expansion modules. The talk highlighted the platform’s technical advantages in building componentized PNT terminal systems.

Dr. Hanxuan Zhang from Harbin Engineering University delivered a technical report on “High-Precision Attitude Estimation and Reliability Assessment Algorithms Based on Miniature Inertial Navigation Systems”. His presentation explored key technological innovations including high-precision consistent modeling under the Lie group framework, adaptive learning of weakly observable dual-noise parameters, and dual-INS spatial calibration based on Lie group modeling.

The exchange was lively and in-depth, with discussions focusing on cutting-edge topics such as UAV swarm control, multi-sensor fusion for pose estimation, microcavity soliton frequency combs, optical gyroscopes, and intelligent navigation platforms. The participants also addressed technical challenges encountered during project implementation and explored plans for future joint research and technological collaboration.

This exchange meeting significantly enhanced communication and cooperation between the project teams, laying a solid foundation for the successful execution of key R&D tasks and the transformation of research outcomes. Both teams agreed that the meeting was pragmatic and productive, playing an important role in deepening research and expanding future collaborations.
