Small consumer-grade drones have rapidly become integral to daily life, with applications such as aerial photography, industrial park inspections, and cargo delivery being widespread. However, alongside industry growth, unauthorized "black flight" activities have increased significantly, accompanied by incidents of malicious intrusions, high-altitude surveillance, and dangerous approaches to critical facilities. Low-altitude safety is no longer a niche concern; densely populated or infrastructure-critical sites—including airports, government complexes, substations, and sports venues—now urgently require robust and reliable low-altitude protection solutions. Shenzhen Zhongke Jiachen Technology Co., Ltd., with years of expertise in low-altitude safety, has developed proprietary drone countermeasures based on two proprietary software patents. These solutions establish a comprehensive technical framework enabling full-process protection from target detection and precise positioning to intelligent response, effectively safeguarding airspace security across diverse real-world scenarios.

1. The practical challenges of low-altitude security have compelled a comprehensive technological upgrade.

Most traditional drone countermeasures available on the market today still rely on outdated full-band electromagnetic interference techniques. When activated, these devices block signals across wide areas, disrupting mobile communications for nearby residents, construction site intercom systems, and road navigation devices, rendering them completely unusable in urban areas, commercial zones, hospitals, and similar locations. Many basic countermeasures have limited detection capabilities; when faced with simultaneous drone intrusions, they can only indiscriminately emit interference signals, making it difficult to target specific drones precisely.

Some devices exhibit poor coordination among their internal modules, resulting in significant delays in signal acquisition, trajectory tracking, and command output. During a major gala event, an external drone intruded into the performance airspace. Security personnel employed conventional countermeasures; however, due to system response latency, the drone remained hovering for nearly twenty seconds before being driven away, significantly disrupting on-site order.

The complex electromagnetic environment continuously tests the stability of equipment. The areas surrounding airports are saturated with various communication and navigation signals, while power equipment within substations consistently emit electromagnetic radiation, making conventional countermeasures prone to signal interference and target loss. The low-altitude security sector currently demands next-generation solutions that offer rapid response, precise positioning, minimal collateral interference, and adaptability to complex environments. Addressing these industry challenges, Zhongke Jiachen has achieved technological breakthroughs at the foundational software level, developing two core software patents that serve as the cornerstone for stable operation of drone countermeasures systems.

2. Two core software patents endow the device with a robust technical foundation

Software copyright represents the most tangible proof of an enterprise's independent R&D capabilities and serves as the "brain" behind intelligent security devices. Zhongke Jiachen holds two core software copyrights: "High-Precision Time Synchronization System Based on BeiDou GPS and Other GNSS V1.0" and "Drone Defense System Based on GNSS Deception Technology V1.0.0." The synergy between these two systems has significantly enhanced the overall performance of its drone countermeasures solutions.

(1) Built on the V1.0 version of high-precision time synchronization systems such as BeiDou and GPS GNSS, it establishes a foundation for stable operation.

Drone countermeasures systems comprise multiple functional modules including signal detection, target localization, trajectory tracking, and command processing; all modules must operate in perfect synchronization for optimal performance. Zhongke Jiachen's self-developed high-precision time synchronization system is compatible with mainstream satellite navigation systems such as BeiDou and GPS, overcoming the limitations of single-source reliance. The system maintains an overall time synchronization error at the nanosecond level, with data exchange and command transmission achieving millisecond-level precision.

When this system is deployed on actual equipment, the most noticeable improvement is a significant enhancement in response speed. At a large-scale sporting event, the security team deployed multiple fixed drone countermeasures to form a networked defense system. Three small drones simultaneously entered the controlled airspace from different directions; the system instantly captured signals, identified each drone's position, altitude, and flight speed within one second, and sent commands to the control module in real time. The simultaneous handling of multiple targets proceeded smoothly without any issues such as target loss or command delays.

In strong electromagnetic environments such as airports and substations, external signal interference is extremely severe. A single satellite signal can easily be suppressed, causing equipment to fail completely. The system features a multi-signal redundancy design: if one satellite signal is interfered with, the remaining signals immediately take over operation. Several major domestic airports have deployed this equipment around the clock for airspace protection for an entire year, enduring harsh conditions including thunderstorms and intense electromagnetic interference, yet the system has maintained uninterrupted operation without any protection failures. Its stable time reference ensures continuous performance of the entire countermeasure system under various complex scenarios.

(2) The UAV defense system V1.0.0 based on GNSS spoofing technology enables precise and flexible response.

The primary limitation of traditional full-bandwidth interference devices lies in their one-size-fits-all protection approach. When deployed in urban commercial areas, such devices render mobile phone signals, store cash registers, and security intercom systems in a 100-meter radius non-functional, imposing significant operational constraints. The GNSS deception defense system developed by Zhongke Jiachen adopts the industry-standard flexible countermeasures strategy, completely eliminating the need for extensive signal blocking.

The system operates on a straightforward principle: it precisely captures the navigation signals of unauthorized drones, generates simulation data that closely resembles real satellite signals, and sends this data specifically to the target drone. Upon receiving these fake coordinates, the drone automatically departs from the controlled area in the preset direction or slowly descends to a designated safe location on the ground. This mechanism is effective only against intruding drones; all surrounding civilian communication, navigation, and electronic devices remain completely unaffected.

The government compound in a certain city center faces significant daily security challenges, with drones frequently hovering outside the perimeter walls to conduct covert surveillance. After deploying countermeasures equipped with this system, the devices immediately activate a decoy mode upon detecting unauthorized flight targets, causing the drones to automatically disengage and fly away toward open areas. The staff's mobile phones, office networks, and security surveillance systems function normally throughout operations, while residents in nearby neighborhoods have never reported any signal abnormalities.

The system is compatible with over 98% of mainstream consumer-grade and industrial-grade drones available on the market, enabling seamless switching between operation modes based on specific scenarios. In densely populated areas such as squares or campuses, the remote evacuation mode is recommended; for remote industrial sites or open spaces, the fixed-point landing mode can be selected. This flexible approach significantly minimizes safety risks associated with drone loss of control and crash landings.

The two software systems form a complete technical closed loop; the high-precision time synchronization system ensures coordinated operation and rapid response across all devices, while the GNSS spoofing defense system enables precise, secure, and interference-free target engagement. This integration of software and hardware delivers comprehensive performance that far surpasses comparable products.

III. Practical Implementation of Technology: Full-range Equipment Coverage for Diverse Application Scenarios

Leveraging technologies from two core software patents, Zhongke Jiachen has developed a comprehensive range of drone countermeasures—including handheld, stationary, vehicle-mounted, and integrated detection-and-strike systems—with each model tailored for specific applications. These solutions have been deployed across numerous security projects nationwide.

The DT900 drone detection and strike system is the primary model widely deployed in industrial plants and parks. It integrates two proprietary software systems, with a signal detection range of up to 3,000 meters and target positioning accuracy within 5 meters. At a large thermal power plant in southern China, where the facility spans a vast area with dense electrical equipment, low-altitude protection poses significant challenges. Four DT900 units are deployed around the site for round-the-clock automated monitoring. During one incident, an aerial drone approached a transmission tower without authorization; the system detected and located it from 2,800 meters away, immediately triggering a decoy operation that guided the drone to land at a designated outdoor area before it could reach critical equipment zones—without any human intervention throughout the process, demonstrating exceptional automated protection performance.

The SDJ800 integrated drone detection and strike device features a compact size and flexible deployment, making it widely used in temporary events and outdoor security operations. During the urban marathon, which spans over ten kilometers, security personnel deployed this device for roadside patrols. Multiple instances occurred where drones flew low above participants; upon activation, security staff swiftly dispersed them within seconds, ensuring event order while preserving normal operation of electronic equipment for pedestrians and roadside businesses.

Mobile countermeasures devices are primarily employed for public security patrols and emergency response operations, providing mobility-based protection alongside vehicles. During peak pedestrian hours in urban commercial districts during holidays, patrol vehicles equipped with these devices traverse streets and alleys to dynamically monitor the entire airspace. This mobile protection mode enables rapid response to unauthorized drone flights, addressing coverage gaps inherent in fixed surveillance systems.

Hospitals, nursing homes, and other environments highly sensitive to electromagnetic fields can also safely utilize Zhongke Jiachen's drone countermeasures equipment. The entire system targets specific drones throughout its operation without interfering with medical monitoring devices, call systems, or network equipment, thereby expanding the application scope of low-altitude security solutions.
