Engineering and technology for low-altitude economy infrastructure

• The low-altitude economy is projected to become a trillion-dollar market within a decade, driving new quality productive forces and strategic emerging industries. • Infrastructure for low-altitude operations requires integration of communication, navigation, surveillance, meteorology, and digital airspace systems, underpinned by 6G, satellite, AI, and digital twin technologies. • The paper identifies four core technology pillars: overall system architecture, information infrastructure, digital airspace and operational management, and security infrastructure. • A special feature in FITEE, led by Prof. Zhijie Chen, aims to accelerate research and engineering innovation in low-altitude economy infrastructure.
