DAJ-100 + Directional Anti-Jamming
Advanced Beamforming
Advanced beamforming controls the phase and amplitude of multiple antenna elements to suppress low-elevation interference and non-line-of-sight signals.
Superior Out-of-Band Rejection
Integrated multi-stage pre-filters effectively suppress adjacent-frequency and out-of-band interference from nearby radio communication systems.
Low Power Consumption
Operation Current ≤150mA
DAJ-100 is a rugged, high-performance directional GNSS antenna designed for reliable positioning and timing in complex RF environments. Its IP67 enclosure makes it ideal for UAVs, aviation platforms, power-grid timing sites, and other fixed GNSS stations.
Advanced Beamforming
Controlled Reception Pattern Antenna (CRPA) array design enables spatial interference suppression and improves positioning robustness.
High RF Integrity
Precision-engineered front-ends with ultra-stable phase centers and out-of-band rejection.
Anti-Jamming Technology
Adaptive spatial filtering and nulling algorithms suppress multiple interference sources while maintaining reliable GNSS signal reception.
Tactical Low-SWaP
Minimized size, weight, and power consumption tailored for high-endurance UAV missions.
Robust Operation
Maintains stable navigation performance under broadband, pulsed, narrowband, and swept-frequency interference conditions.
Field Resilience
Ruggedized design tested for extreme vibration, thermal shock, and high-dynamic flight.
