36Kr discovered that Chengdu Dagongbochuang Information Technology Co., Ltd. (hereinafter known as “Dagongbochuang”), a supplier of electromagnetic house safety options, not too long ago introduced the completion of a Pre-A spherical of financing value tens of thousands and thousands of yuan. This spherical was invested by an industrial investor, and the funds raised might be used for core know-how iteration, product line enlargement, and the improve of the headquarters base capabilities.
Dagongbochuang was established in 2014 and focuses on the analysis and improvement and product manufacturing of radio spectrum administration and management, and drone detection and countermeasure applied sciences. It is a specialised and complicated enterprise in Sichuan Province. The founder, Xia Lihua, is a grasp from the University of Electronic Science and Technology of China. In the early years, she labored in a army analysis institute, engaged in analysis on digital countermeasure applied sciences, and has wealthy expertise in army scientific analysis and the transformation of army and civilian applied sciences. The different founding members embody professors from 985 universities, senior engineers, and properly – recognized antenna consultants within the trade.
Dagongbochuang’s core R & D workforce has been deeply concerned in digital countermeasure applied sciences for practically 30 years, mastering core applied sciences for radio spectrum monitoring and route discovering, corresponding to related interferometers, spatial spectrum estimation, phased – array antennas, excessive – velocity broadband knowledge acquisition, and multi – channel sign evaluation. It has obtained practically 200 licensed mental property rights.
According to Gong Jue, the corporate’s secretary of the board and funding director, Dagongbochuang’s product matrix has absolutely coated situations within the electromagnetic house safety discipline, corresponding to drone detection, countermeasures, and supervision. At the top of 2024, Dagongbochuang launched the complete – band (20MHz – 8GHz) drone detection and route – discovering gadget – “Tianmu”, which might successfully determine, detect, and find varied frequency – variable modified drones (non – cooperative targets).
Currently, “Tianmu” has achieved mass manufacturing and is utilized in a number of situations. By the top of this yr, after Dagongbochuang completes its manufacturing capability improve, the entire manufacturing capability of drone detection and countermeasure gadgets and radio spectrum detection gadgets, together with “Tianmu”, will improve to 2,000 units per yr.
Comprehensive help car for “full – band” drone administration and management
“Tianmu full – band” drone detection and route – discovering gadget
Drone monitoring covers the complete frequency band, attaining a steadiness between 100% localization and excessive efficiency
In latest years, public security incidents corresponding to drone interference with flights and intrusions into delicate areas have occurred ceaselessly. The “low, small, and slow” traits of drones make conventional safety measures troublesome to deal with. Units corresponding to airports, giant – scale occasion venues, and key infrastructure have an pressing want for skilled low – altitude safety merchandise and options. The enthusiasm on the utility finish has additionally unfold to the capital finish. Since 2024, there have been a number of giant – scale financings with single – transaction quantities exceeding 100 million yuan within the home low – altitude safety market.
Although there are various producers on the planet doing drone countermeasures, in Gong Jue’s view, Dagongbochuang has relative benefits in frequency band protection and technical depth.
In phrases of frequency band protection, “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, relating to the differential benefits of Dagongbochuang’s “full – band” merchandise, Gong Jue stated, “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 phrases of technical depth, Dagongbochuang’s R & D workforce has greater than 20 years of technical accumulation within the electromagnetic discipline. “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 know-how, adapt to situations properly, and speed up the internationalization course of
At current, the low – altitude safety market has shifted from competing on “who can make products” to competing on “who can deepen technology and adapt to scenarios well”.
On the state of affairs facet, Dagongbochuang’s drone countermeasure merchandise are presently utilized in a number of main occasion safety, border protection, and aviation situations. On the know-how facet, Dagongbochuang’s workforce predicts that the longer term improvement development of drone countermeasure know-how is “full – band and full – space management and control, distributed intelligent perception, and the interconnection of military and civilian technologies“. In response, the workforce has been making related technical layouts.
In phrases of full – band protection, Tianmu 2.0 of Dagongbochuang will proceed to iterate on the core algorithm to enhance the accuracy of drone identification; in phrases of distributed notion, Dagongbochuang makes use of low – price radio – frequency sensors mixed with AI algorithms, and the positioning accuracy may be diminished to sub – meter stage; in phrases of the interconnection of army and civilian applied sciences, Dagongbochuang has utilized the army’s “rapid deployment” know-how to civilian help autos, lowering the set up time to fifteen minutes. At the identical time, it’s also making use of civilian AI algorithms to the army scenario evaluation system.
Dagongbochuang has been established for 11 years, and its home enterprise has continued to develop, attaining steady profitability for a number of years. From a medium – to lengthy – time period improvement perspective, along with consolidating its home basis, Gong Jue believes that internationalization may also be an inevitable path for Dagongbochuang’s low – altitude safety enterprise enlargement. Considering the robust abroad demand for drone countermeasure merchandise, the administration plans to take part in additional abroad exhibitions with merchandise ranging from 2026 and progressively discover markets within the Middle East, Southeast Asia, Europe, and so forth. As of now, Dagongbochuang has obtained a number of on – hand and meant orders for abroad drone countermeasure merchandise.
By the top of this yr, Dagongbochuang’s merchandise and manufacturing capability might be additional expanded: In phrases of merchandise, Dagongbochuang will launch the Tianmu full – band 2.0 drone detection and route – discovering gadget, an extended – distance drone RID receiving gadget geared up with the newest radio – frequency receiving know-how, and a low – price grid – based mostly resolution for drone and pilot detection in city low – altitude areas; in phrases of manufacturing capability, Dagongbochuang will promote the development of the third and fourth manufacturing strains. After the development is accomplished, the entire manufacturing capability of its drone detection and countermeasure gadgets and radio spectrum detection gadgets will attain 2,000 units per yr.
