Interference and jamming, whether deliberate or accidental, can substantially impair the functionality of GPS systems, affecting positioning, navigation, and timing accuracy, and may even result in complete signal loss. standard GNSS antennas frequently enough struggle to maintain performance in environments plagued by such disruptions.To counteract this, specialized antennas are essential for improving the quality of desired signals while effectively filtering out unwanted interference, ensuring optimal receiver operation.
Advanced Anti-Jamming Antennas for Enhanced Signal Integrity
The JH001, JH002, and JH003 models represent cutting-edge GNSS antennas designed wiht exceptional anti-interference features, offering markedly improved performance over conventional antennas in settings with moderate interference. Utilizing advanced techniques such as beamforming, pre-multiple filtering, and polarization suppression, these antennas excel in rejecting out-of-band signals and minimizing multipath interference.
