Abstract:UAV is the core carrier and key driving force in the low altitude economy. The UAV industry has gradually become a strategic emerging industry that takes into account the coordinated development of new productivity and industrial innovation. Based on the development status of low altitude UAV in China, this paper analyzes the current industrial scale and management classification of low altitude UAV. The main technical bottlenecks of large-scale commercial application of low altitude UAVs are analyzed. It is concluded that the industry development in the future needs to focus on three strategic technical fields, namely, UAV power energy, 5g satellite integrated communication and airspace intelligent management. Discussions are carried out around aircraft power solutions in low altitude economic environment, UAV communication and data processing technology, and low altitude airspace management and safety technology. It is proposed that these technological breakthroughs and industrial upgrading have significant synergistic effects, which can effectively enable the construction of intelligent and efficient low altitude economy industry, and is the key to unlock the huge potential of low altitude economy and ensure its safe and reliable operation.
