In the airport control tower's monitoring room, air traffic controllers watched a sudden unidentified light source appear on the radar screen, their palms breaking out in cold sweat—this was not a bird but a drone that had illegally entered the controlled airspace. In 2025, flight delays caused by unauthorized drone flights in China surged by 40% year-on-year, while low-altitude intrusions near energy facilities, large events, and public security zones also increased dramatically. These seemingly distant security threats are gradually becoming reality with the widespread adoption of consumer-grade drones. Against this backdrop, Shenzhen Zhongke Jiachen Technology Co., Ltd. leveraged two nationally certified core software copyrights and advanced smart manufacturing lines to develop a comprehensive drone countermeasures system covering the entire process of "detection – identification – counteraction," establishing an invisible digital barrier for low-altitude safety management.

Backed by dual software copyrights, we transform industry pain points into a robust technological competitive advantage.

Many people are unaware that numerous anti-drone devices on the market either employ blanket, full-frequency-band interference that contaminates even surrounding civilian signals, or suffer from poor positioning accuracy—firing indiscriminately at approximate directions and proving ineffective against unconventional targets such as modified drones or stealth aircraft. The two software patents obtained by Zhongke Jiachen precisely address these common industry shortcomings.

"Full-Frequency Band UAV Defense System V1.0.0 Based on High-Power RF Module Control" addresses the challenge of precise countermeasures. This system captures target drones 'communication signals in real time, automatically analyzes their frequency bands, power levels, and flight trajectories, then dynamically adjusts its interference strategy: for standard consumer-grade drones, it prioritizes disrupting the 2.4 GHz/5.8 GHz remote control links; for industrial-grade drones equipped with GNSS anti-jamming modules, it switches to satellite navigation frequencies for precise suppression. Real-world test data from an airport in Guangdong show the system's response time is under 1 second, achieving a 98% success rate in jamming mainstream drone models within a 1–3 km range, with false-trigger rates below 3%. Even modified surveillance aircraft can be accurately identified and forced to land without interfering with nearby mobile phones or walkie-talkies.

Another system, titled "Spectrum-Based Multi-Station Fusion Positioning Defense System V1.0.1," has achieved industry-leading precision in positioning accuracy. Traditional single-site detection devices often exhibit positioning errors of several dozen meters for drones, rendering them incapable of providing reliable coordinates for subsequent response actions. In contrast, Zhongke Jiachen's system deploys multiple spectrum monitoring nodes in critical areas and employs a triangulation algorithm to achieve centimeter-level positioning. During a security test at a major concert, staff covertly installed four monitoring points around the venue; when a drone took off from a distance of 1.2 kilometers, the system identified the signal and predicted its trajectory within two seconds, achieving a positioning error of less than 5 meters, enabling security personnel to quickly locate the operator based on the coordinates. More importantly, the system can simultaneously track up to 20 target signals without experiencing any detection blind spots even when faced with a drone swarm.

These two systems operate in seamless integration rather than being isolated: upon detecting a target, the multi-site positioning system immediately transmits its coordinates and frequency band information to the countermeasure system, which promptly generates the optimal interference strategy, establishing a closed-loop defense mechanism of "detection followed by immediate action." Numerous customers report that with Zhongke Jiachen's equipment, they no longer need to guess target locations blindly or randomly select interference frequencies as before.

A full-end intelligent manufacturing production line that transforms laboratory technologies into equipment capable of withstanding real-world application.

No matter how advanced an algorithm or system is, if the resulting equipment frequently malfunctions, it remains nothing more than a mere laboratory demonstration. Zhongke Jiachen fully understands this principle; from component selection to final product manufacturing, every step adheres to military-grade standards to ensure stable performance in harsh environments such as remote areas, coastal regions, and low-temperature conditions.

Components are the heart of any equipment. Zhongke Jiachen employs only industrial-grade components for its RF modules, power amplifiers, and signal processing chips, with all critical components being independently designed and manufactured. Taking the high-power RF module as an example: many commercially available modules tend to overheat and experience frequency reduction—or even complete failure—when operating at high power for extended periods. Zhongke Jiachen's engineers have optimized the circuit layout and thermal management design; during an 8-hour continuous laboratory test, the temperature of the core components remained within safe limits without a single instance of frequency reduction. Each batch of components undergoes three rigorous quality checks—including spectrum analysis, high/low-temperature stress testing, and aging evaluation—before entering inventory; substandard units are immediately returned to suppliers and never proceed to production.

Upon entering the production workshop, the automated SMT assembly line operates at high speed, while AOI optical inspection equipment scans each circuit board individually, leaving no installation deviation, even the slightest one, undetected. For critical components such as control boards, workers apply a three-layer protective coating—specifically designed to resist moisture, corrosion, and salt spray—ensuring reliable performance whether deployed at coastal nuclear power plants or in harsh northern environments with temperatures below zero degrees Celsius, without malfunctions caused by moisture or frost accumulation. Module assembly follows a standardized modular design: RF modules, power modules, and control modules are assembled and tested separately; each module undergoes comprehensive functional testing—including signal transmission power, frequency accuracy, and interference resistance—before proceeding to the next stage of production.

The pre-manufacturing testing of the entire device is exceptionally rigorous, bordering on extreme. In the company's electromagnetic compatibility laboratory, the equipment undergoes temperature cycling tests ranging from-40°C to +70°C, vibration and shock tests simulating truck movements, as well as electromagnetic compatibility tests to ensure it neither interferes with surrounding devices nor disrupts their normal operation. At outdoor simulation test sites, technicians use various drone models to repeatedly evaluate the device's detection range, positioning accuracy, and anti-interference performance at different distances, altitudes, and interference conditions until all specifications meet design requirements. Each unit carries a unique product serial number, enabling complete traceability—from component batches and manufacturing processes to test data—within the system. Every device delivered to customers is a product refined through rigorous testing and development.

Multi-scenario adaptation transforms a "single device" into a "customized solution"

With robust technological and production capabilities as its foundation, Zhongke Jiachen's drone countermeasures equipment spans various types—including fixed, handheld, and vehicle-mounted models—making it suitable for low-altitude security needs across diverse scenarios.

At critical facilities such as airports and nuclear power plants, fixed countermeasure systems serve as the primary defense solution. Installed at strategic high points, these systems provide round-the-clock monitoring of airspace and integrate with existing security surveillance networks. Upon detecting drone intrusions, they immediately trigger automated alerts, track flight paths, and activate countermeasures. A security official at a coastal nuclear power plant noted that previous manual patrols were insufficient to cover the vast airspace; since implementing Zhongke Jiachen's fixed system, comprehensive coverage has been achieved alongside precise localization of operators across multiple sites. Last year alone, three unauthorized intrusion incidents were successfully resolved.

Handheld countermeasures devices prove invaluable in large-scale events and temporary security scenarios. Weighing less than 3 kilograms, these devices can be operated with one hand and deliver effective interference over a range of up to 1.5 kilometers. During a sports event security operation in 2025, officers patrolled the venue area equipped with these devices; upon detecting an unauthorized drone intrusion, they could instantly activate full-bandwidth jamming to force the aircraft to land within 10 seconds without disrupting operations. Many security personnel reported that the device offers excellent grip comfort, requires minimal training for operation, and remains easy to handle even during prolonged use.

The vehicle-mounted countermeasure system is a powerful tool for mobile security. It can be integrated into command vehicles and patrol cars, maintaining stable signal transmission and interference capabilities throughout vehicle operation. During public security mobile operations, the system moves alongside patrol vehicles while continuously monitoring the surrounding airspace; upon detecting suspicious drones, the command center can remotely activate countermeasures and simultaneously receive real-time positioning data from the devices, enabling "patrol-and-defense integration" during movement.

Beyond hardware solutions, Zhongke Jiachen also develops customized defense strategies tailored to clients' specific scenarios. For instance, in response to drone swarm attacks, they design multi-site coordinated countermeasures where multiple devices operate simultaneously to suppress target signals from various directions. For drones operating on modified frequency bands, they employ spectrum analysis algorithms in their software to rapidly identify signal characteristics and generate targeted interference strategies—ensuring precise effectiveness even against devices operating in niche frequency ranges.

We continue to deepen our technological efforts, further strengthening the safeguards for low-altitude safety.

The pace of development in the low-altitude economy dictates the speed of technological iteration required for countermeasures against drones. Modern drones are becoming increasingly intelligent and more resilient to interference, with specialized "counter-countermeasure" technologies now emerging—posing greater challenges to countermeasures themselves. At Zhongke Jiachen, over 40% of the workforce is dedicated to R&D, with 15% of annual revenue allocated to this area, ensuring the company stays abreast of industry advancements.

Engineers are continuously refining the algorithms of two core software systems, including the integration of AI-based signal recognition models to enable faster identification of signal characteristics from new types of drones, and the optimization of multi-site positioning coordination algorithms to enhance positioning accuracy in complex environments. Additionally, they are collaborating with universities and research institutions to develop countermeasures for drone swarms and high-jamming-resistant drones, exploring integrated solutions encompassing detection, identification, counteraction, and verification.

In the future, Zhongke Jiachen will continue to expand its product portfolio by introducing more low-altitude security devices tailored for various scenarios and enhancing its end-to-end after-sales service—including installation, commissioning, technical training, equipment upgrades, and maintenance—to ensure customers can use their products with confidence and ease. The company firmly believes that low-altitude safety cannot be achieved with a single device alone; it requires sustained technological innovation, reliable product quality, and comprehensive solutions to effectively safeguard every airspace.

From groundbreaking algorithmic innovations in the lab to precision manufacturing on production lines and practical applications across diverse scenarios, every move by Zhongke Jiachen addresses the core challenges of the low-altitude security industry. By leveraging two patented software solutions to strengthen technical foundations, employing smart manufacturing to uphold quality standards, and delivering customized solutions tailored to client needs, the company has emerged as a trusted force in the field of low-altitude safety.
