Anti-jamming antenna AJ410

The AJ410 Series Anti-Jamming Antenna is a high-performance integrated solution designed to ensure uninterrupted and precise positioning for UAVs (Unmanned Aerial Vehicles) and other aerial platforms operating in contested or complex electromagnetic environments. It combines a Controlled Reception Pattern Antenna (CRPA) with an integrated Digital Antenna Control Unit (DACU). The system utilizes a self-developed anti-jamming SoC chip and advanced polarization-space-time-frequency adaptive nulling algorithms to identify and suppress multiple types of interference in real-time. This guarantees that your drone’s navigation system receives a clean, reliable GNSS signal, which is fundamental for flight safety, mission accuracy, and operational success

OPERATIONAL HIGHLIGHTS

 

Product Advantages for UAVs

Ensures Mission-Critical Reliability: Directly addresses the core challenge of GNSS signal vulnerability, which is a leading cause of UAV loss of control or “fly-away” incidents. By maintaining a stable positioning solution, it safeguards your asset and mission data.

Superior Multi-Threat Suppression: Its advanced algorithm can effectively counteract up to three different jamming sources at once, covering the most common and complex interference types encountered in real-world scenarios. This provides a significant advantage in high-stakes or congested airspace.

Maintains High Positioning Accuracy: By protecting the critical L1 frequency and providing a clean, amplified L2 signal, the antenna supports high-precision positioning techniques like RTK (Real-Time Kinematic), which is essential for professional surveying, mapping, and precision agriculture with drones.

Integrated & Optimized Design: The fusion of the CRPA and DACU into a single unit simplifies integration into UAV platforms, saving space, weight, and power—key considerations for airborne applications where every gram counts.

The AJ410 is engineered for UAV platforms that cannot afford navigation failure:

Military & Security UAVs: Reconnaissance, surveillance, and target acquisition missions in electronically contested environments.

Critical Infrastructure Inspection: Protecting navigation signals for drones inspecting power lines, pipelines, or communication towers near potential sources of RF interference.

PPR (Public Protection & Disaster Relief) Operations: Ensuring reliable drone navigation during emergency responses where communication networks may be overloaded or compromised.

High-Precision Commercial & Industrial Drones: Safeguarding the operation of drones used for precision agriculture, surveying, and mapping where centimeter-level accuracy is required.
