直击第十届北京军博会，低空安全防护技术成本届焦点

Group 1 - The 10th China (Beijing) Military Intelligent Technology Equipment Expo showcased over 500 domestic enterprises and presented more than 3,000 cutting-edge technology products and solutions across various sectors, including command information systems, new-generation information technology, unmanned combat equipment, simulation training, artificial intelligence, and low-altitude technology [1][3]. - The expo highlighted the construction of a low-altitude safety protection system as a key topic, reflecting the growing importance of low-altitude safety in both military defense and the development of the low-altitude economy [3][5]. - Shanghai Tejin Company introduced its latest unmanned aerial vehicle (UAV) detection and countermeasure products, including a TDOA (Time Difference of Arrival) grid management system, aimed at addressing the challenges of "position-based" UAV defense [3][5]. Group 2 - The H3L UAV detection and positioning device and the H2D UAV reconnaissance and strike integrated device are portable, meeting the regulatory needs for UAV and pilot positioning, flight trajectory tracking, and UAV disposal [5]. - The TDOA UAV detection and positioning device can detect invading UAV targets within a range of 2-5 kilometers, and when multiple devices are networked (≥4), they can track common models like DJI and less common models, providing an all-weather, intelligent low-altitude UAV defense solution [5]. - The chairman of Shanghai Tejin emphasized the expo's role as a significant platform for showcasing new technologies and products, aiming to enhance industry and societal awareness and investment in low-altitude safety [5].
