Dagong Technology DG-M20 Tethered UAV Inducted into National Museum: Reshaping Air-Space-Ground-Sea Emergency Communication

Beijing, China — On March 10, 2025, China's network communication sector witnessed a milestone event: the DG-M20 Tethered UAV System, independently developed by Beijing Dagong Technology Co., Ltd., was officially inducted into the "New Achievements in Network Development Exhibition" at the National Museum of China. As an industry benchmark, Dagong Technology's equipment took centre stage at this highest-specification showcase, celebrated for its groundbreaking contributions to "Air-Space-Ground-Sea Integrated" emergency communication technology. This prestigious induction signifies the nation's ultimate recognition of tethered UAVs empowering the low-altitude economy and disaster rescue, marking Dagong Technology's magnificent transformation from a technology follower to a global trailblazer in this specialised field.

Enshrined in the National Museum: The "Fiber Optic + Power Composite Cable" Lifeline
The National Museum exhibition outlined China's march toward a cyber powerhouse across four thematic chapters. At the intersection of "Integrated Empowerment" and "Universal Benefit," Dagong Technology’s tethered UAV system demonstrated irreplaceable strategic value. Traditionally, emergency communication has relied heavily on ground base stations, which can easily turn disaster zones into information "islands" during massive catastrophes. Founded in 2015 as the domestic pioneer in tethered UAV R&D, Dagong Technology targeted this critical vulnerability. In 2017, jointly with China Mobile, they launched the world's first emergency communication high-altitude base station system. Pioneering a "fiber optic + power composite cable" technology, the system supplies continuous power to the UAV and its payload via a tether, achieving 24-hour uninterrupted aerial hovering, a 5-kilometre signal coverage radius, and concurrent access for 1,500 users. This originally Chinese technology made its international debut at the 2018 Mobile World Congress (MWC) in Barcelona, acclaimed by global industry experts as a "revolutionary technology reshaping disaster rescue communication paradigms."

Battle-Hardened: The "Aerial Backbone" from Disaster Rescue to National Ceremonies
The DG-M20 enshrined in the National Museum is far from a mere laboratory specimen; it is an "aerial backbone" forged through dozens of major disasters and national-level missions. In the darkest hours of life-saving operations, Dagong Technology acted as the guardian of information channels. During the 2017 Jiuzhaigou earthquake, the system restored communication within 3 hours, illuminating a lifeline for over 3,000 trapped tourists. In the 2022 China Eastern Airlines crash rescue, it rapidly constructed on-site communication networks. During the 2023 "Doksuri" typhoon rescue across the Beijing-Tianjin-Hebei region, with 80% of power facilities destroyed, Dagong Technology's tethered UAVs stubbornly defended the communication lifeline for 72 consecutive hours. Most recently, in the 2025 Shigatse earthquake in Tibet, the tethered UAV high-altitude base station collaborated with Beidou short-message emergency services for the first time, realising a new generation of satellite-ground fusion communication.

During moments of national celebration, Dagong Technology served as the eye that captured history. As the exclusively designated tethered UAV supplier for China Central Television (CCTV), Dagong's systems carried broadcast-grade cameras during the 70th National Day and the Centenary of the Founding of the Party. By breakthroughly achieving 12G bandwidth real-time transmission, it broadcast the panoramic splendour of the central axis to the world, pioneering a new era in large-scale event broadcasting technology. Furthermore, the company's equipment collaborated with large fixed-wing UAVs to construct Air-Space-Ground integrated communication networks in the "Emergency Mission" exercises organised by the Ministry of Emergency Management, earning high commendation from the headquarters.

Innovation Iteration: From 400m Altitude Ceiling to Navigation Reconstruction
Being enshrined in the National Museum is not the finish line, but the starting point for Dagong Technology's continuous iteration. Founded by an elite Tsinghua University team, the company consistently maintains technological leadership. At the 2024 Shenzhen UAV Conference, Dagong Technology released the epoch-making DG-M40, a 400-metre altitude ceiling tethered UAV system, once again breaking the operational height limits and drastically expanding signal coverage. The recently debuted DG-X50 pushes the ceiling beyond 600 metres. Even under Level 8 gusts and complete GNSS denial environments, leveraging its original "Navigation Reconstruction" technology and high-precision optical sensor arrays, it achieves centimetre-level autonomous positioning and stable hovering.

Currently, Dagong Technology has constructed a comprehensive product matrix covering 50 to 400 metres and beyond, accumulating over 90 independent intellectual property rights and deeply participating in formulating multiple industry standards. The company has been successively recognised as a Beijing "Specialized and Sophisticated" SME, a National High-Tech Enterprise, and a Beijing "Gazelle" Enterprise. It also won first place in the Ministry of Industry and Information Technology's Emergency Communication High-End Equipment Selection.

As the exhibition curator noted, these exhibits are not cold equipment, but monuments of the era cast with the innovative passion of tech workers. On the new journey of building a comprehensive emergency communication system and low-altitude economy new quality productive forces, Beijing Dagong Technology will continuously guard the light of life with technological innovation, racing toward becoming the globally leading industrial-grade UAV solution provider.
