2023 National Atlas Inclusion: Dagong Technology's Tethered UAV Certified as Standardised Emergency Communication Equipment

Dongguan / Beijing — On May 19, 2023, at the Natural Disaster Prevention Technology and Equipment Innovation Summit Forum, the release of the authoritative Natural Disaster Prevention Innovation Equipment Application Case Atlas marked a definitive paradigm shift in China's emergency management architecture. Within this official directive, Beijing Dagong Technology Co., Ltd.’s tethered UAV system was officially incorporated as a critical national case study—elevating the platform from a mere "innovative product" to an indispensable, standardised strategic asset for emergency communication and disaster reconnaissance, unequivocally proving that a single photoelectric composite cable is the backbone of the nation's "Air-Space-Ground Integrated" rescue network.

The atlas inclusion is far more than a product showcase; it represents a strategic leap, signalling that Dagong Technology’s tethered UAV has transcended "technical validation" to achieve "tactical integration." In the eyes of the state's emergency management authorities, the system's ability to deploy rapidly and maintain 24-hour uninterrupted hovering via its specialised tether cable resolves the fundamental endurance curse of traditional drones. It has transformed from a simple flying platform into a persistent aerial node—essential for restoring communication, providing illumination, and conducting reconnaissance in the extreme "Three Disconnections" scenarios (road, network, power outages). This official recognition effectively upgrades the tethered UAV from a "usable" option to a "must-have" standardised solution for national disaster response.

This prestigious listing is the direct culmination of a decade of rigorous R&D by Dagong Technology, validated by icy data from the most unforgiving environments. The atlas recognition is anchored in three hard-core technological pillars:

First, defining the new standard of "persistent existence." By delivering continuous ground power through its proprietary tether, the system achieves 24-hour—and beyond—continuous滞空 (hovering). During the 2018 Qinghai "Tianyi Shenjian" drill, it operated flawlessly for 24 hours straight at an altitude of 2,261 meters in -3°C conditions, acting as an indefatigable "aerial sentry" during the critical 72-hour golden rescue window.

Second, setting the industry benchmark for extreme performance. Endurance must be matched with heavy-lift and stability. The system effortlessly carries a 35kg payload at a 300-meter altitude—sufficient for heavy communication base stations and fire monitors—whilst maintaining rock-solid positioning with a mere ±0.8m error margin against Level 7 gusts (15.5m/s). Furthermore, its deployment time from ground to full signal coverage is a staggering 23 minutes, rendering traditional communication vehicles, which require days to establish, obsolete.

Third, ensuring sovereign security through full-chain innovation. From flight control algorithms to power management, Dagong Technology holds complete autonomous intellectual property. It was the world's first tethered UAV system to obtain the MIIT's network access certification in 2017. Capitalising on the 374-square-kilometre premium airspace of the Beijing Yanqing Drone Industrial Park—where one can "push the door and fly"—the company has forged a highly agile, closed-loop ecosystem of R&D, testing, and production that guarantees absolute reliability.

The atlas is the manual of capability, but Dagong Technology’s reputation was forged in the fires of actual national emergencies. Long before 2023, the system had already translated technical specifications into life-saving combat power. In the 2017 Jiuzhaigou earthquake, it executed the first domestic combat deployment of a tethered drone emergency high-altitude base station, restoring communications within three hours. It illuminated the levees during the 2021 Henan mega-floods and safeguarded rescue operations during the 2022 China Eastern Airlines crash. Beyond disaster, it served as the flawless "Eye in the Sky" for the 70th National Day and CPC Centenary celebrations, providing CCTV with millimeter-level precision broadcasts from above Tiananmen Square.

The 2023 atlas inclusion served as a launchpad for the low-altitude economy era. As applications explode from emergency rescue into high-rise firefighting (up to 330 meters), smart city governance, and critical infrastructure inspection, Dagong Technology’s tethered UAV is cementing its position as "New Aerial Infrastructure." Bolstered by the Ivy Capital Series B financing and its DG-M20 system's subsequent induction into the National Museum of China, the market has voted with its feet.

From the laboratories of Tsinghua and Beihang, to the earthquake ruins of Jiuzhaigou, and now onto the pages of state directives, Dagong Technology’s single tether cable does more than anchor a drone—it anchors a nation's unwavering step towards modernising disaster prevention and commanding the trillion-yuan low-altitude economy.
