NAVAIS NS-200 CRPA GNSS Anti-Jamming Antenna

NAVAIS NS-200 CRPA GNSS Anti-Jamming Antenna

The NAVAIS NS-200 is an integrated CRPA (Controlled Reception Pattern Antenna) GNSS anti-jamming system designed for mission-critical positioning and navigation in interference-prone environments. Its multi-element adaptive architecture detects and suppresses RF interference while maintaining dual-frequency GNSS signal availability.

Unlike a conventional GNSS antenna, the NS-200 applies real-time anti-interference processing to broadband, narrowband, multi-tone, tone, sweep, pulse and continuous-wave interference. It provides conditioned high-precision signals to compatible GNSS receivers.
