Revolutionizing Low-Altitude Security: The MOPTECH Multi-Target AOA System
nnIn an era where unauthorized drones pose an increasing threat to sensitive airspace—from airports and government buildings to stadiums and critical infrastructure—the need for a robust, intelligent, and non-disruptive countermeasure solution has never been greater. The MOPTECH Multi-Target AOA Low-Altitude Precision Control System emerges as a comprehensive answer to this complex challenge. It is not merely a detection tool but a fully integrated ecosystem that combines early warning, precise direction finding, and targeted countermeasures into one seamless platform. Designed for the most demanding core-area security environments, this system offers a blend of passive detection and active defense that ensures compliant flight operations remain untouched while hostile targets are neutralized with surgical precision.nnThe system’s ability to handle over 20 simultaneous aerial threats without emitting any detectable signals makes it a game-changer for security professionals. By operating silently, it provides a stealthy security perimeter that cannot be detected or evaded by sophisticated drone operators. Furthermore, its robust construction, featuring an IP65 rating and an impressive operating temperature range from -40°C to 65°C, guarantees reliable 7×24 operation in the harshest climatic conditions, from freezing tundra to scorching deserts. Adaptive cooling and low power consumption (≤50W for the detector, ≤58W standby for the jammer) ensure continuous, eco-friendly performance without the need for constant manual intervention.nn
Core Capabilities: Detection, Direction Finding, and Jamming

Detection and Direction Finding (AOA)
nnThe heart of the MOPTECH system lies in its advanced Angle of Arrival (AOA) technology. This method uses multiple antennas to pinpoint the exact direction of a radio frequency (RF) signal emitted by a drone. Unlike radar, which broadcasts its own energy, AOA is a passive technique. This means it cannot be detected itself, making it ideal for covert security operations. The system scans the spectrum from 100MHz to 6GHz, covering the vast majority of commercial and hobbyist drone frequencies. It can simultaneously detect and track more than 20 targets, providing a 360-degree hemispherical view of the protected airspace. With a direction-finding accuracy of 3° to 10° and a positional error of just ≤10m, operators can quickly and accurately assess the location and trajectory of every threat. This capability is further enhanced by compatible multi-station networking, which leverages TDOA (Time Difference of Arrival) precision for advanced trajectory tracking, creating an impenetrable multi-layered security bubble.nn
Multi-Target AOA and Precision Countermeasures
nnThe defining feature of this system is its integrated and intelligent response. Upon detection, the platform does not just identify the threat; it actively engages it with a targeted jamming solution. This is where the concept of precise countermeasures comes to life. The system is equipped with eight distinct jamming bands, including dedicated channels for the most critical frequencies used by drones: 2.4GHz, 5.2GHz, 5.8GHz, 433MHz, 900MHz, 1.2GHz, 1.4GHz, and 1.5GHz. Each channel can be independently controlled and modulated to deliver a specific, powerful signal. The system can execute a one-to-one strike, focusing a precise jamming beam on a single targeted drone, severing its control and navigation links. This highly focused approach is what makes the system safe for use in sensitive areas, as it does not flood the entire spectrum with noise, thereby avoiding interference with civilian aircraft or other legitimate communications. The entire process, from detection to successful jamming, occurs in under five seconds.nn
Intelligent Black/White List Management and API Integration
nnModern security is not just about brute force; it is about intelligence and discrimination. The MOPTECH system supports dynamic black and white lists. For example, a white list might include a security team’s own surveillance drone or a delivery drone with a known flight plan. The system will automatically ignore these authorized aircraft, preventing false alarms and unnecessary jamming. Conversely, any unlisted drone is immediately flagged as a potential threat. This feature, combined with trajectory playback for forensic analysis and standard API access for integration into larger command-and-control centers, makes the MOPTECH system an intelligent, adaptable component of a modern security framework. It allows operators to customize their defense perimeter to the specific needs of their location, whether that is a temporary event or a permanent installation.nn
