China achieves breakthrough in underground space navigation

Theoretical breakthroughs, technological innovation, chip development, and practical applications... Dedicated to solving the challenges of long-distance, large-capacity, high-precision autonomous positioning and unmanned navigation control services in large underground spaces, this National Key R&D Program project "High-Precision Positioning, Navigation and Control Technology for Large Underground Spaces," led by the National Key Laboratory of Integrated Spatiotemporal Networks and Equipment Technology of the Network Communication Research Institute, has successfully passed acceptance by the Ministry of Science and Technology, marking a major original achievement in China's integrated spatiotemporal network direction for underground spaces. The intelligent navigation service for underground parking lots that Chen Chong experienced is supported by the "Xingyuan" BeiDou micro-base station underground space positioning and navigation system developed by the team at the National Key Laboratory of Integrated Spatiotemporal Networks and Equipment Technology of the Network Communication Research Institute.
