Four Elements Dual Bands Anti-Interference Terminal
The Four Elements Dual Bands Anti-Interference Terminal operates on dual-frequency B1&L1&E1+L2 with 20-megahertz main and secondary bandwidth. Dimensions measure 135 by 130 by 38 millimeters weighing under 350 grams. The device requires 12-volt DC power with 10-watt consumption. Single-interference rejection reaches 90 decibels-carrier while multiple-interference rejection achieves 80 decibels-carrier. Spatial domain 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 capability against jamming signals.
The terminal receives BD-B1, GPS-L1, GALILEO E1 and GLONASS G1 signals, outputting navigation positioning information with anti-interference function. NMEA0183 navigation data outputs through RS-232C serial port with SMA-JYD backup connectivity. Multi-constellation signal processing simultaneously tracks GPS L1/L2, GLONASS G1/G2, Galileo E1/E5b, and BeiDou B1/B2/B3 signals. Dual-frequency architecture provides redundant positioning if single-band jamming disables primary frequency reception. Advanced adaptive filtering suppresses out-of-band interference while maintaining signal integrity. Real-time processing enables instantaneous navigation data delivery to flight control systems.
The Four Elements Dual Bands Anti-Interference Terminal deploys across unmanned aerial vehicle navigation, tactical positioning operations, and military flight control applications. UAV systems employ this terminal for reliable positioning in contested electromagnetic environments. Dual-frequency redundancy ensures positioning continuity during jamming events. Field operations demonstrate robust performance in hostile signal environments where single-frequency receivers fail.
Tactical Supply Pakistan supplies this beamforming anti-interference solution with four-element antenna design and advanced signal processing. The compact form factor integrates directly into UAV flight control architectures. J30J-9Z/KP interfaces enable rapid system integration. Wide temperature range supports extreme climate deployment.
Does the terminal continue positioning when primary B1/L1 bands experience jamming?
Yes, the dual-frequency architecture automatically processes secondary L2 band signals when primary frequencies face interference, maintaining continuous positioning during active jamming targeting the 1575.42 MHz band.
