Product Overview
The AJU-X200 carries a sixteen-element CRPA array with an ultra-high-dynamic anti-jamming algorithm that adapts to complex electromagnetic environments and retains reliable positioning on high-dynamic platforms. It withstands up to fifteen simultaneous jammers at 80 dB and a single source at 110 dB, the strongest protection level in the AJU family for large UAVs and special vehicles. Typical applications: Large and long-endurance UAVs, high-dynamic special vehicles, autonomous driving, high-shock environments.
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; seven jammers ≥ 100 dB; fifteen 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
