The PALS PAIR-20 is a cutting-edge, highly integrated airborne antenna system engineered to provide robust, high-throughput Ka-band satellite connectivity for the most demanding aerial platforms, including fixed-wing aircraft and UAVs. It combines a high-efficiency parabolic feed network, low-noise amplifier, servo control, and GPS/BeiDou positioning into one compact unit, designed to enhance operational capabilities.
Performance is paramount. The PAIR-20 achieves rapid satellite acquisition with a cold-start time under 80 seconds (under 60 seconds hot-start). Its advanced two-axis stability and three-axis tracking system ensures high accuracy, maintaining a tracking error of <0.5dB RMS. Even during aggressive maneuvers, its stability algorithm keeps the link locked. The system also offers swift signal recovery—under 3 seconds for short blockages.
Built for resilience, its modular design enables straightforward field maintenance and diagnosis. This makes the PAIR-20 a critical, reliable asset not only for military applications—boosting combat effectiveness and mobility—but also for mission-critical emergency response communications across public safety, fire, transportation, and civil defense agencies, ensuring a vital lifeline during disasters.
