At this year’s National Two Sessions, "fostering the low-altitude economy" was included in the government work report for the first time. Developing the low-altitude economy has become a key engine for advancing the construction of a modern industrial system, accelerating the development of new quality productive forces, and actively nurturing emerging and future industries. The vigorous development of the low-altitude economy has driven the rapid popularization of UAV (Unmanned Aerial Vehicle) products. According to data from the Civil Aviation Administration of China, by the end of 2023, the number of registered UAVs in China had exceeded 1.267 million. Currently, UAV technology and applications have penetrated various aspects of society.

However, as the "flying boom" and "aerial photography boom" continue to gain momentum, incidents such as unauthorized aircraft intruding into key sensitive areas, interfering with the normal flight of civil aviation aircraft, and leaking national defense secrets through aerial photography have become increasingly frequent. These incidents severely disrupt air traffic order and pose threats to public security, privacy protection, and even national security.

As a leader in UAV technology, China has not only promoted the vigorous development of the UAV industry but also provided fertile ground for innovation in UAV countermeasure technology. It has attracted numerous enterprises and entrepreneurs to establish themselves in the field of UAV countermeasures, building an important defense line for safeguarding national security and ensuring public order. Yunsang Jindou (Nanjing) Technology Co., Ltd. (hereinafter referred to as "Yunsang Jindou") is a high-tech enterprise focusing on the R&D of low-altitude UAV defense products and safety supervision systems. By integrating advanced technologies such as radio frequency identification and protocol analysis, the enterprise has successfully achieved accurate detection and effective control of UAVs, building a solid defense line for low-altitude security.

In 2018, China’s consumer and industrial UAV market boomed, with a total market size of 11.2 billion yuan, which gave rise to the emergence of the UAV countermeasure industry. At that time, Guo Xinyang, the founder of Yunsang Jindou, was working in a technology company in Beijing, engaged in R&D of UAV countermeasure technology. As a result, Guo Xinyang led his team to become "pathfinders" in China’s UAV countermeasure field and successively completed several 10-million-level UAV countermeasure security projects. In 2021, Guo Xinyang decided to start his own business and founded Yunsang Jindou in Nanjing, focusing on research in the UAV countermeasure field.

For a long time, Nanjing has gradually formed a complete system integrating R&D, manufacturing, and application in the low-altitude economy industry. This system not only relies on the talent supply and experience accumulation of many universities and research institutes in core links such as UAV technology R&D and manufacturing but also benefits from Nanjing’s attention and strong support for the low-altitude economy industry. The introduction of a series of support policies such as the Nanjing Implementation Plan for Promoting the High-Quality Development of the Low-Altitude Economy (2024-2026) and the Several Measures of Nanjing on Supporting the High-Quality Development of the Low-Altitude Economy, as well as policy plans to support the development of the aviation industry around the "2+6+6" innovative industrial cluster, will provide long-term support for Nanjing to compete for the title of "Low-Altitude City" and build significant industrial agglomeration effects and competitive advantages.

Leveraging Nanjing’s solid industrial chain advantages in the low-altitude security field and abundant talent resources, Guo Xinyang, through accurate market positioning and continuous technological innovation, successfully promoted Yunsang Jindou to achieve rapid development from scratch and from small to large in just three years. Currently, the core team members of Yunsang Jindou not only include technical talents from prestigious universities such as Southeast University and Hohai University but also absorb experts and senior backbones from leading industry enterprises such as the US Fortemedia R&D Center and ZTE Corporation. With the combined effect of these factors, Yunsang Jindou has achieved an annual revenue scale of tens of millions within three years and paid more than one million yuan in taxes each year.

In the process of UAV countermeasures, only by accurately identifying the target UAV can the effectiveness and pertinence of subsequent countermeasures be ensured. This requires the system to accurately capture the signals and characteristics of UAVs in complex environments and ensure accurate targeting. Currently, the types of UAVs on the market are increasingly diverse, and their technical levels are constantly improving. Traditional single monitoring and defense methods are difficult to cope with complex and changing practical situations, and the difficulty of accurately identifying UAV targets and implementing effective countermeasures is also increasing.

In June 2023, Yunsang Jindou was invited to participate in an important figure protection technical service activity held by a public security department in Ningxia. This activity aimed to ensure the safety and order of the airspace in specific areas through advanced technological means and provide solid technical support for the activities of important figures. During the event, Yunsang Jindou’s UAV countermeasure product was the only one that successfully identified and intercepted the latest model of communication equipment from a leading domestic UAV manufacturer, becoming a major "highlight" at the scene and winning high praise from the leaders and technical personnel of the participating public security departments.

The strong detection and control capabilities of Yunsang Jindou’s products mainly come from three dimensions: scenario and system optimization, product technology iteration, and the adoption of an integrated hardware-software development model. In terms of scenarios, Yunsang Jindou focuses on the "1+1+3N" scenarios where UAVs are mainly used, such as chemical and petroleum industries, airports, and urban low altitudes, and formulates systematic and personalized solutions. In terms of products, Yunsang Jindou has established a complete product system covering detection, jamming, surveillance-strike integration, and defense, and continuously introduces cutting-edge technologies for upgrading and iteration to ensure sufficient and leading technical reserves. Compared with other domestic manufacturers that adopt a single detection mode, Yunsang Jindou uses a combination of multiple detection sources, enabling its products to achieve a spectrum identification distance of 7.5 km, a 24/7 false alarm rate controlled at 0.5%, and a 24/7 missed alarm rate within 1%, resulting in more advanced product detection capabilities and jamming effects.

In addition, Yunsang Jindou’s independently developed control platform, as the core support for its business, can integrate multiple data sources, including spectrum detection information and video monitoring data. Through the comprehensive access of fixed, portable, and mobile devices, it realizes real-time monitoring, early warning, and intelligent disposal of low-altitude flight activities. At the same time, compared with platforms developed by other manufacturers, Yunsang Jindou’s control platform can monitor the working status of UAVs in real time, enabling efficient and accurate control of UAV activities, thereby significantly reducing the false alarm rate and missed alarm rate of UAV countermeasure technology and effectively improving the stability and reliability of the UAV defense system.

Relying on its integrated "scenario + product + system" solution, Yunsang Jindou has significantly optimized the efficiency and accuracy of low-altitude supervision, achieving a leap in supervision efficiency. In April this year, Yunsang Jindou was invited to be responsible for the low-altitude security work of the 2024 Yancheng Marathon and the Grand Canal Marathon Series (Yancheng Station). The event had a scale of 15,000 participants and covered 42 kilometers of land. The large number of people and complex and changeable regional conditions undoubtedly created major challenges for the low-altitude security work. Yunsang Jindou brought its JDY-900 UAV defense system to provide comprehensive low-altitude protection for the event. A single station of this system can achieve detection and positioning within a radius of 3,000 meters and countermeasures within a radius of 2,000 meters. It can also display the data of UAV countermeasure equipment on Yunsang Jindou’s control system in the form of data visualization, further realizing full-coverage low-altitude detection and accurate countermeasures within a large range.

As an emerging field, the UAV countermeasure industry is currently in the early stage of its development. With the popularization of UAV technology and the expansion of application fields, the demand for UAV countermeasure technology will grow increasingly, especially in fields such as low-altitude defense and security monitoring.

Connecting upstream and downstream enterprises in the industrial chain, assisting enterprises in market expansion, promoting the transformation of research results... With a series of empowerment support from Nanjing Innovation Investment Group, Yunsang Jindou has achieved rapid growth.

"The rich post-investment empowerment and strong state-owned capital endorsement have helped the enterprise consolidate its market position and accelerate the expansion of its business territory," Guo Xinyang said. On the one hand, thanks to this investment, Yunsang Jindou has achieved significant improvements in R&D capabilities and production line construction capabilities, successfully overcoming many difficulties and phased development obstacles faced in the early stage of entrepreneurship. As a result, the enterprise has been able to establish its own competitive advantages earlier and faster, and in the current environment of disorderly competition in the industry, it has accumulated the ability to break through industry bottlenecks, thus becoming a new force contributing to the innovative development of the regional UAV countermeasure industry.

With the rapid development of the low-altitude economy and the in-depth advancement of low-altitude airspace management reform, the construction of city-level low-altitude supervision platforms has gradually become a key focus of various regions and leading industry enterprises in recent years. However, at the same time, city-level low-altitude supervision platforms also have extremely high requirements for integrated air-ground information service capabilities, intelligent and automated flight control levels, system integration capabilities, and scenario adaptability.

"Yunsang Jindou aims to become a pioneer enterprise in escorting the low-altitude economy. By adopting core radio signal identification algorithms, building a unified UAV control platform, creating the ‘1+1+3N’ scenario model, and integrating AI technology, it will continuously iterate intelligent space security solutions to empower the intelligent and refined management of urban low-altitude airspace," said Guo Xinyang.

The mass entrepreneurship investment team of Nanjing Innovation Investment Group stated: "As an emerging economic development model, the low-altitude economy is still in the early stage of development. To promote the sustained and healthy development of this field, more enterprises with high growth potential like Yunsang Jindou are needed to form the backbone of industry development, and work together to guide and promote China’s low-altitude economy to move toward a higher level." In the next step, the team will continue to implement the national, provincial, and municipal strategic plans for the development of the low-altitude economy, seize the strategic opportunity of intensive innovation and high-speed growth in the low-altitude economy, assist the growth of small and medium-sized innovative enterprises in the low-altitude economy within the province, and promote Nanjing to build a national innovation highland and service hub for the low-altitude economy.
