Description

1. General Description

AX04 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.

AX04 Anti-Jam CRPA System can be employed using various configuration and operates with civil and military GPS receivers for the land, sea, air platforms (including unmanned aerial systems) and fixed installations. The product has an embedded GNSS receiver that supports all satellite constellations.

2. How It Works

AX04 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
  • Minimal integration training required
  • Light Weight
  • Ultra Compact Size
  • Superior Suppression Performance

4. Application Areas

  • Fixed Winged Aircraft
  • Rotary Wing Aircraft
  • Unmanned Autonomous Systems
  • Armored Vehicles
  • Naval Platforms, Coast Guard Platforms
