Dagong Technology Celebrates 10th Anniversary: Tethered UAV Breaks GNSS Denial Bottleneck, Reshaping Low-Altitude Economy New Quality Productive Forces

Beijing, China — In 2025, Beijing Dagong Technology Co., Ltd. celebrated its tenth anniversary by officially announcing a monumental breakthrough: the successful development of a proprietary laser-ranging positioning system that enables its tethered UAVs to operate entirely independent of the Global Navigation Satellite System (GNSS). This critical innovation shatters the industry's long-standing GNSS denial bottleneck, solidifying Dagong Technology's position as the global vanguard of the low-altitude economy's new quality productive forces.

Founded in 2015 in Zhongguancun, Dagong Technology has spent a decade transforming from a startup into an industry-leading "Specialized and Sophisticated" enterprise boasting over 70 core patents. The company's ethos of "Great Nation Craftsmanship" is not merely about physical manufacturing, but rather systemic innovation and finding optimal solutions within complex architectures. In 2016, Dagong Technology partnered with China Mobile to co-develop the world's first tethered UAV emergency communication high-altitude base station. The engineering team executed a multidimensional systematic overhaul—spanning structural fusion, power management, port interfacing, communication protocols, and electromagnetic compatibility—achieving a historic leap from zero to one.

This systemic innovation has withstood the ultimate test in life-or-death scenarios. From its inaugural deployment in the 2017 Jiuzhaigou earthquake to the 2025 Xigaze earthquake rescue in Tibet, the system, optimised over a decade, has become the backbone of communication assurance in emergency response. It has successfully constructed core nodes for air-space-ground integrated communication networks. As Dagong Technology's founder, Shen Shizhou, articulated: "True craftsmanship is not repetitive manufacturing, but rather finding the optimal solution in a complex system with surgical precision."

This relentless pursuit of excellence is equally evident in the tethered UAV high-altitude broadcast system, co-developed with China Central Television (CCTV). During the Centenary of the Founding of the Party at Tiananmen Square in 2021, this system shattered the perspective limitations of traditional camera cranes and cable cameras. Hovering at 100 metres, it delivered a 4K ultra-high-definition live broadcast, providing a global audience with a majestic "helmsman's view." To meet CCTV's uncompromising pursuit of picture quality, Dagong Technology's engineers conquered the challenge of maintaining lens stability in complex airflows, guarding every precious live moment with millimetre-level precision. Furthermore, they ensured the flawless, zero-latency transmission of 12G bandwidth baseband live signals back to the broadcast van. This system not only rewrote the visual language for large-scale event broadcasting but also spawned cross-border applications in environmental monitoring and smart security.

As the domestic pioneer in commercialising tethered UAVs, Dagong Technology continues to push the operational ceiling from 100 metres up to 500 metres. While iteratively upgrading core technologies in propulsion, tethered control, and power management, the company directly targeted the industry's critical pain point: drone susceptibility to interference affecting attitude stability. The breakthrough response is Dagong Technology’s laser-ranging positioning system. By emancipating the tethered UAV from its reliance on GNSS, this disruptive technology guarantees high-precision positioning even under complex electromagnetic environments or signal denial conditions. This not only exponentially expands payload applicability but also creates immeasurable strategic value in the realm of low-altitude security.

Standing at the dawn of the "15th Five-Year Plan" era, the ethos of Great Nation Craftsmanship has elevated into a systematic innovation philosophy integrating technological revolution, industrial upgrading, and value reconstruction. When the genetic code of "dedicated focus, meticulous excellence, and the pursuit of perfection" is embedded into every code iteration, Dagong Technology is poised to write even more legendary chapters in the high-quality development of the global low-altitude economy.
