Product Overview
The AJU-8130 integrates an eight-element CRPA array with a high-dynamic anti-jamming algorithm, resisting up to seven simultaneous jammers (85 dB) and 110 dB against a single source. It is designed for medium and large UAVs, autonomous driving platforms and special vehicles that must keep precise navigation in heavily contested RF environments. Typical applications: Medium and large UAVs, autonomous driving and special vehicles, police security and border patrol.
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 ≥ 110 dB; three jammers ≥ 100 dB; seven jammers ≥ 85 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
