Product Overview
The AJU-8160D pairs two eight-element arrays for dual-band B1/L1/E1+L5 operation with adaptive nulling in 2-D space, allowing it to combat complex, multi-directional interference while continuing to track L5. High power handling (36 W) and an optional heatsink make it suitable for long-endurance manned and unmanned aircraft operating near strong jamming emitters. Typical applications: Long-endurance UAVs and manned aircraft, high-value industrial UAVs, maritime platforms.
Key Features
- CRPA (controlled reception pattern) antenna array that adaptively nulls jamming sources while keeping the GNSS main beam on satellites
- Suppresses wideband, narrowband, frequency-sweep and pulse jamming, and combinations of these, on GPS L1 / BDS B1 / Galileo E1; capability: Single jammer ≥ 105 dB; three jammers ≥ 90 dB; seven jammers ≥ 80 dB (J/S @ -130 dBm)
- Built-in multi-constellation GNSS receiver outputs NMEA positioning data (GGA/GSV/RMC/VTG/ZDA) over the data interface
- SMA-K anti-jammed RF output, J30J power-and-data connector, 50-ohm matching with VSWR <= 2.0
- IP65 protection, -40C to +70C operating range, shock and vibration tested per UAV environmental standards
