Abstract: Low-altitude economy, as a strategic emerging industry in China, represents a comprehensive economic ecosystem centered on flight activities of new intelligent vehicles such as unmanned aerial vehicle (UAV) and electric vertical takeoff and landing aircraft (eVTOL), driving multi-domain development in low-altitude. However, existing air traffic management systems struggle to address the complex requirements of diversified, high-density, and heterogeneous collaborative operations of low-altitude aircraft. low-alltitude intelligent networked technology enables efficient management and large-scale application of low-altitude airspace by integrating communication, navigation, surveillance, and service infrastructure through coordinated technological approaches. This paper focuses on the practical operational requirements of low-altitude airspace management and systematically analyzes the feasibility of key technological solutions—such as 5G mobile communication, BeiDou differential positioning, and integrated sensing and communication surveillance—within typical low-altitude operational scenarios. The findings provide a technological roadmap and theoretical foundation for low-altitude airspace management, and support the modernization of China's airspace management system and the strategic deployment of emerging industries.
