Four Elements Dual Bands Anti interference terminal (Enhanced version)
The Four Elements Dual Bands Anti interference terminal (Enhanced version) operates on triple-frequency B1&E1&L5 with 20-megahertz main and secondary bandwidth. Dimensions measure 135 by 130 by 38 millimeters weighing under 350 grams. Power requirement is 12-volt DC with 10-watt consumption. Single-interference rejection reaches 90 decibels-carrier while multiple-interference achieves 80 decibels-carrier. Spatial coverage spans 0 to 360 degrees azimuth and -90 to +90 degrees elevation. Operating temperature ranges -45 to +70 degrees Celsius. The four-element antenna array provides beamforming against jamming signals across all three frequency bands.
The enhanced L5 band operates at 1176 megahertz co-located with GPS L5 and Galileo E5a signals, delivering higher positioning precision and availability. Multi-constellation processing simultaneously tracks GPS L1/L5, BeiDou B1/B3, Galileo E1/E5, and GLONASS L1/L2 signals. NMEA0183 navigation data outputs through J30J-9Z/KP serial port with SMA-JYD backup connectivity. Triple-band architecture provides redundant positioning if jamming disables primary frequencies. Advanced adaptive filtering suppresses out-of-band interference. Real-time processing enables instantaneous navigation delivery to flight control systems.
The Four Elements Dual Bands Anti interference terminal (Enhanced version) deploys across unmanned aerial vehicle navigation, tactical positioning, and military flight control applications. UAV systems employ this terminal for reliable positioning in contested electromagnetic environments. Triple-frequency redundancy ensures positioning continuity during multi-band jamming. Field operations demonstrate robust performance in hostile signal environments where dual-frequency systems fail.
Tactical Supply Pakistan supplies this beamforming anti-interference solution with four-element antenna design and triple-band processing. The compact form factor integrates directly into UAV flight control architectures. Enhanced L5 capabilities provide centimeter-level accuracy in surveying operations. Wide temperature range supports extreme climate deployment.
How does the enhanced L5 band improve positioning accuracy over standard dual-band systems?
The L5 band at 1176 megahertz reduces multipath errors through wider bandwidth allocation. Triple-band diversity provides centimeter-level accuracy when all bands achieve signal lock versus meter-level accuracy with single-frequency systems.
