Anti-Jamming capacity
Protected Frequencies
Jamming Types Suppressed
Dual-Band Robust Protection for Mission Assurance: Unlike single-band solutions, the AJ440 provides concurrent protection for key UAV navigation frequencies like L1 and L2. This dual-layer defense not only counters intentional jamming but also mitigates common co-frequency interference, ensuring reliability for critical military reconnaissance, logistics delivery, and swarm operations.
Guarantees High-Precision Positioning Performance: By purifying and outputting multi-frequency signals like L2, the AJ440 establishes a solid foundation for drones equipped with Real-Time Kinematic (RTK) or Precise Point Positioning (PPP) modules. This ensures centimeter-level accuracy essential for surveying, mapping, and precision agriculture applications.
Adaptive & Intelligent Anti-Jamming: The built-in advanced algorithm continuously senses the interference environment. It automatically generates optimal “nulls” across polarization, space, time, and frequency domains to precisely suppress jammers without manual intervention, significantly enhancing UAV survivability in dynamic, complex settings.
Integrated, Lightweight Design: The highly integrated architecture reduces external cables and separate processing units. This simplifies integration onto UAV platforms, minimizing weight and power consumption—crucial factors for payload and space-sensitive drone designs.
