Title: Precision measurement of geomagnetic vectors   using diamond color centers and matching navigation

Abstract: Navigation and positioning information serves as the   foundation for precise target acquisition,   command decision-making, operational control, and firepower strike.   Traditional inertial navigation and positioning systems   suffer from severe accumulated errors and safety risks during prolonged   operation in rugged underground environments, making geomagnetic navigation   the optimal alternative to GPS. This report addresses navigation challenges for both manned / unmanned platforms in confined underground spaces and   underwater geomagnetic navigation / submarine detection. Focusing on issues such as   satellite signal penetration difficulties in denied environments and the lack   of absolute spatial references in unknown territories, it proposes high-precision solid-state quantum measurement mechanisms for geomagnetic vectors paired with   matching navigation methods. These   innovations resolve critical problems including: tri-axis magnetic   measurement with quantum sensors, high-precision attitude testing, and   geomagnetic positioning. The breakthroughs provide crucial technical support for   national major projects and key defense sectors, particularly in magnetic map   construction and autonomous navigation of unmanned systems.

Title: Four-peak   tracking autonomous omni-directional CPT atomic Magnetometer and its   application

Abstract: Omni-directional measurement of the   geomagnetic field in satellites is necessary. Coherent population trapping   (CPT) atomic magnetometer is theoretically capable of omni-directional   measurement of magnetic fields, but it requires a reference signal in the direction   of the magnetic field. To solve this problem, a new control method was   proposed in this report to trap four CPT signals. This control method does   not require a fluxgate magnetometer to provide the magnetic field direction   for mode switching and can obtain continuous magnetic data without losing   lock in the range of 0°~360°.   Finally, several application cases are presented.

Biography: Xuefeng   Wang received his B. Sc. degree from Wuhan Technical University of Surveying   and Mapping in 1997 and his Ph. D. degree from Shanghai Institute of Optics   and Fine Mechanics, Chinese Academy of Science in 2002. He has won multiple   awards, including the Second Prize for National Technical Invention. Now he   is a researcher of Beijing Institute of Aerospace Control and Devices, and   the director of the Quantum Engineering Research Center of China Aerospace   Science and Technology Corporation Limited. His primary research interests   include optical and quantum measurement.

Title: Perception and   Navigation Technologies for Low-Altitude Unmanned Vehicle

Abstract: Low-altitude unmanned   vehicle heavily rely on satellite navigation, facing critical   challenges such as limitations in cost-effective navigation and positioning   solutions, difficulty in rapid situational awareness within non-cooperative   environments, and barriers to autonomous operation. This talk analyzes the   growing demands of the low-altitude economy for high-precision autonomous   navigation, and highlights key technologies including visual/LiDAR-based   perception and navigation, and trustworthy localization frameworks applicable   to low-altitude unmanned aerial and ground vehicles.

Biography: Professor and   doctoral advisor at Nanjing University of Aeronautics and Astronautics   (NUAA), serving as Director of International Cooperation Office. His research   focuses on inertial and satellite navigation, integrated navigation, and   perception-based navigation for unmanned systems. He is a recipient of   several prestigious honors, including National High-level Talent Programs,   the Second-tier Talent Program of Jiangsu Province's "333 Project,"   and the Civil Aviation Administration of China's Distinguished Innovator   Award. He serves as Deputy Director of the Key Laboratory of Advanced   Navigation, Control and Health Management for Aircraft, Ministry of Industry   and Information Technology, and leads NUAA’s Top 100 Innovation Team on   Advanced Navigation Technologies for Aerospace Vehicles. He is also an   executive council member of the Chinese Society of Inertial Technology and   the Jiangsu Society of Automation.

Title: Exploration of building human habitational   station based on lava tub on extraterrestrial planets

Abstract: In 2019, China's Chang 'e-4 mission carried out the first biological experiment   on the moon, carrying six kinds of organisms, including potatoes, cotton,   rape, Arabidopsis, fruit flies and yeast, to form a miniature ecosystem and   cultivate two green leaves, which were evaluated by nature and science as the   first green leaves on the human moon. Its background and creative sources   will be comprehensively introduced. Development basis and influence. And the   studies have suggested that caves are widespread on the Moon, Mars, and even   across the solar system. As compared to the ground, building bases in caves   on these extraterrestrial bodies have notable advantages. For this purpose,   our team investigated dozens of caves with different types in Chongqing.   Karst landforms are widely developed and complete in Chongqing, including   skylights, ground seams, dark rivers, shafts, and other special landforms.   Most of these caves are arched structures (like lava tubes) with a radius of   a few meters to several tens of meters and a length of several thousand   meters, or tens of thousands of meters (enough for simulation (meeting   simulation needs). Caves stretch in a winding manner, with complex crisscross   structures and isolated darkness inside. We suggest that karst caves on Earth   can be used as testbeds for extraterrestrial cave bases under certain   intentions, such as isolated dark environments, complex structures, and huge   spaces that humans may face in future extraterrestrial lava tubes. Despite   their differences in formation mechanisms and rock properties, unique   gravity, and dimensional differences. And we attempted to build an integrated   simulation base in a karst cave in Chongqing, China.

Biography: Prof. Gengxin Xie, professor, Director of the Institute of Aerospace Science and   Technology, Chongqing University; As the chief designer of the   biological experiment payload of the   Chang’e-4 mission, led the team to   solve six key technical problems and successfully grew the first ever green   leaf on the moon. This achievement has been highly valued by the national leadership   and relevant ministries and commissions and has been reported more than 60   million times by thousands of domestic and foreign media, such as CNN, BBC,   TIME, Nature, Science, the official website of the State Council of the   People’s Republic of China (www.gov.cn), CCTV, People’s Daily, Science and   Technology Daily, Zaobao (Singapore), Reference News, Global Times and so on,   receiving great repercussion around the world. Among them, the   international journal Science praised it as "in the first for mankind"   and Nature praised it as "the pioneering experiment". He is now   leading his team to conduct research based on the karst caves in Chongqing,   simulating the establishment of bases by humans on the moon and Mars in the   future. He has presided more than 10 national projects, won 1 first prize of   the National Natural Science Award of the Ministry of Education, 1 first   prize   of the National Award for Technological Invention   of the Ministry of Education, and 1 second prize of the National Science and   Technology Progress Award. He has published 4 books and more than 60 papers,   obtained more than 20 national patents.
