Description

1. General Description

AX05K Anti-Jam CRPA System supports critical missions by providing jam free GNSS signals.

With an 8-array CRPA antenna, the system can assure the normal operation of GNSS receiver in presence of multiple jamming sources.

The AX05K is also available with anti-spoofing. By leveraging proprietary GNSS technology, the AX05K enhances protection against jamming and spoofing attacks, ensuring robust and reliable navigation of weapon platforms in environments threatened by jamming and spoofing signals. The combination of these advanced technologies makes the AX05K a comprehensive solution for GNSS-based security across a variety of platforms.

2. How It Works

AX05K mitigates interference by creating nulls in the antenna gain pattern in the direction of jammers, providing significant anti‑jam protection even in dynamic multi‑jammer scenarios. The output is a protected standard Radio Frequency (RF) signal, free from jamming and suitable for input to modern and legacy GNSS receivers.

3. Key Benefits

  • Immediate availability for urgent operational needs
  • Simple assembly means easy to install or retrofit
  • Compatible with all types of external GPS receivers and vehicle navigation systems
