16-Element CRPA GNSS Anti-Jamming Antenna YT280 110dB 15-Jammer Suppression Anti-Spoofing GPS L1 B1I B1C E1 for UAV

Product Description 

Product Overview

The YT280 is a 16-element CRPA (Controlled Reception Pattern Antenna) system built for GNSS environments where interference is strong and continuous. It receives and digitally combines 16 channels of B1I/L1/B1C/E1 signals (1568±10MHz) through an adaptive beamforming array, delivering reliable suppression against up to 15 simultaneous broadband jammers — the highest interference-handling capacity in its class.

Beyond jamming rejection, the 280-16B1N2 integrates civil GNSS anti-spoofing technology that detects and mitigates both generative (synthetic) and relay (meaconing) spoofing. This dual-defense design keeps positioning and timing integrity intact for platforms that cannot tolerate navigation failure.

With a 280mm rugged enclosure, ±70℃ temperature range and standard TNC / MS3112E14-19P interfaces, the 280-16B1N2 is ready for direct system integration.
