36Kr learned that Chengdu Dagongbochuang Information Technology Co., Ltd. (hereinafter referred to as "Dagongbochuang"), a provider of electromagnetic space security solutions, recently announced the completion of a Pre-A round of financing worth tens of millions of yuan. This round was invested by an industrial investor, and the funds raised will be used for core technology iteration, product line expansion, and the upgrade of the headquarters base capabilities.

Dagongbochuang was established in 2014 and focuses on the research and development and product manufacturing of radio spectrum management and control, and drone detection and countermeasure technologies. It is a specialized and sophisticated enterprise in Sichuan Province. The founder, Xia Lihua, is a master from the University of Electronic Science and Technology of China. In the early years, she worked in a military research institute, engaged in research on electronic countermeasure technologies, and has rich experience in military scientific research and the transformation of military and civilian technologies. The other founding members include professors from 985 universities, senior engineers, and well - known antenna experts in the industry.

Dagongbochuang's core R & D team has been deeply involved in electronic countermeasure technologies for nearly 30 years, mastering core technologies for radio spectrum monitoring and direction finding, such as relevant interferometers, spatial spectrum estimation, phased - array antennas, high - speed broadband data acquisition, and multi - channel signal analysis. It has obtained nearly 200 authorized intellectual property rights.

According to Gong Jue, the company's secretary of the board and investment director, Dagongbochuang's product matrix has fully covered scenarios in the electromagnetic space security field, such as drone detection, countermeasures, and supervision. At the end of 2024, Dagongbochuang launched the full - band (20MHz - 8GHz) drone detection and direction - finding device - "Tianmu", which can effectively identify, detect, and locate various frequency - variable modified drones (non - cooperative targets).

Currently, "Tianmu" has achieved mass production and is applied in multiple scenarios. By the end of this year, after Dagongbochuang completes its production capacity upgrade, the total production capacity of drone detection and countermeasure devices and radio spectrum detection devices, including "Tianmu", will increase to 2,000 sets per year.

In recent years, public safety incidents such as drone interference with flights and intrusions into sensitive areas have occurred frequently. The "low, small, and slow" characteristics of drones make traditional security measures difficult to cope with. Units such as airports, large - scale event venues, and key infrastructure have an urgent need for professional low - altitude security products and solutions. The enthusiasm at the application end has also spread to the capital end. Since 2024, there have been several large - scale financings with single - transaction amounts exceeding 100 million yuan in the domestic low - altitude security market.

Although there are many manufacturers in the world doing drone countermeasures, in Gong Jue's view, Dagongbochuang has relative advantages in frequency band coverage and technical depth.

In terms of frequency band coverage, "Foreign drone countermeasure manufacturers, such as DroneShield in the United States and OpenWorks Engineering in the United Kingdom, have well - known brands and started internationalization early. However, they have poor compatibility with domestic drone models such as DJI, and their frequency band coverage is incomplete. Many devices only cover the fixed frequency bands of 2.4/5.8GHz and are useless when encountering modified frequency - hopping drones. Dagongbochuang's 'Tianmu' drone detection and direction - finding device achieves continuous coverage and high - speed scanning of the entire frequency range (20MHz - 8GHz) used by drone systems and can accurately identify modified DIY racing drones with frequency - hopping capabilities."

In addition, regarding the differential advantages of Dagongbochuang's "full - band" products, Gong Jue said, "Most mainstream products on the market use the 'fence - type protection technology' of frequency band splicing, but there are always gaps between the fences. We use the full - band and full - airspace high - speed scanning technology, which will not miss any scanning point."

In terms of technical depth, Dagongbochuang's R & D team has more than 20 years of technical accumulation in the electromagnetic field. "Most domestic drone countermeasure manufacturers are integrators. We are one of the few original manufacturers with both in - depth independent R & D capabilities and military product qualifications. In addition, our current drone countermeasure products have achieved a balance between localization and high performance. Our products can be 100% localized, and their performance has been verified in military and information technology application innovation scenarios."

Deepen technology, adapt to scenarios well, and accelerate the internationalization process

At present, the low - altitude security market has shifted from competing on "who can make products" to competing on "who can deepen technology and adapt to scenarios well".

On the scenario side, Dagongbochuang's drone countermeasure products are currently applied in multiple major event security, border defense, and aviation scenarios. On the technology side, Dagongbochuang's team predicts that the future development trend of drone countermeasure technology is "full - band and full - space management and control, distributed intelligent perception, and the interconnection of military and civilian technologies". In response, the team has been making relevant technical layouts.

In terms of full - band coverage, Tianmu 2.0 of Dagongbochuang will continue to iterate on the core algorithm to improve the accuracy of drone identification; in terms of distributed perception, Dagongbochuang uses low - cost radio - frequency sensors combined with AI algorithms, and the positioning accuracy can be reduced to sub - meter level; in terms of the interconnection of military and civilian technologies, Dagongbochuang has applied the military's "rapid deployment" technology to civilian support vehicles, reducing the installation time to 15 minutes. At the same time, it is also applying civilian AI algorithms to the military situation analysis system.

Dagongbochuang has been established for 11 years, and its domestic business has continued to grow, achieving continuous profitability for several years. From a medium - to long - term development perspective, in addition to consolidating its domestic foundation, Gong Jue believes that internationalization will also be an inevitable path for Dagongbochuang's low - altitude security business expansion. Considering the strong overseas demand for drone countermeasure products, the management plans to participate in more overseas exhibitions with products starting from 2026 and gradually explore markets in the Middle East, Southeast Asia, Europe, etc. As of now, Dagongbochuang has obtained several on - hand and intended orders for overseas drone countermeasure products.

By the end of this year, Dagongbochuang's products and production capacity will be further expanded: In terms of products, Dagongbochuang will launch the Tianmu full - band 2.0 drone detection and direction - finding device, a long - distance drone RID receiving device equipped with the latest radio - frequency receiving technology, and a low - cost grid - based solution for drone and pilot detection in urban low - altitude areas; in terms of production capacity, Dagongbochuang will promote the construction of the third and fourth production lines. After the construction is completed, the total production capacity of its drone detection and countermeasure devices and radio spectrum detection devices will reach 2,000 sets per year.
