Core Insights - The first International Low Altitude Economy Expo was held in Shanghai, showcasing nearly 300 exhibitors and exploring the construction path of a "Sky City" [1][4]. Group 1: Major Announcements - Shanghai Volant Aviation received a letter of intent for a purchase order totaling $1.75 billion, setting a record for the largest single "air taxi" order in China [4]. - The Shanghai eVTOL large-scale assembly manufacturing base consortium was established, aiming to support the development of eVTOL and other low-altitude industries [10]. - The East China (Yangtze River Delta) Low Altitude Economy Industry Alliance was unveiled, expected to assist Shanghai in building a "Sky City" [4][10]. Group 2: Industry Collaboration - The East China Low Altitude Economy Industry Alliance includes seven civil aviation and unmanned aerial vehicle test zones, as well as prominent universities, to promote high-quality development of the low-altitude economy [6][10]. - The consortium for the eVTOL assembly base will leverage Shanghai's advantages in large aircraft, engines, and aviation talent to accelerate the development of new aviation technologies [10][11]. Group 3: Market Potential - The Civil Aviation Administration of China projects that the low-altitude economy market will reach 1.5 trillion yuan by 2025 and 3.5 trillion yuan by 2035, highlighting its potential as a new growth point for regional economic development [10]. Group 4: Technological Challenges - Experts emphasized the need for a digital, autonomous, and collaborative low-altitude traffic management system to address the challenges of high-density low-altitude operations [15][16]. - The construction of a low-altitude smart network is seen as a key support for the development of the low-altitude economy, with 6G technology expected to provide essential technical support [16][17]. Group 5: Event Highlights - The expo featured over 60,000 square meters of exhibition space, attracting nearly 300 companies and showcasing 19 global product launches and 25 domestic product launches [17].

当然，过去一年多以来，各地也都密集推动低空管控平台建设，已经取得一些突破。国家层面已经建成无人驾驶航空器一体化综合监管服务平 台，全国首家省级无人机管理服务平台 ——安徽省低空无人机管理与服务平台，以及成都市低空交通管理服务平台等市级平台也已经运行一 年左右，"目前已经形成了国家-省-市-区低空管控系统的标准产品"。 "我们亟需一套规则，一套完备的平台。这个平台就相当于低空经济的'中枢神经'，延伸出去基础设施网、低空感知及通信的空联网等'四张 网'。"张建平认为，这是低空经济发展的突出短板，也是需要各地长期投入的事情。 他认为，从低空管控而言，我们主要面临三个瓶颈问题——空域精细化管理水平低导致"无路飞"、低空态势感知难导致"看不见"、引导控制能 力弱导致"管不住"。比如，过去基于三维物理空间的空域建模方法已经无法满足空域划设的多信息源需求，"要考虑城市复杂环境，以及敏感 区域、动态障碍等"。 与此同时，我们传统的对中高航空器感知技术不再适用于低空、超低空运行新场景。这些都给低空管控平台的建设带来挑战。 "未来低空经济要热起来，首先大量的低空飞行器要先飞起来。我们未来面临的将是一个大流量、强耦合、高时变的飞行 ...
