Description

1. General Description

AX14 Anti-Jam CRPA System supports critical navigation missions by providing stable, jam-free GNSS signals for space-constrained and lightweight platforms.

Equipped with a high-precision 4-array CRPA antenna, the system guarantees the normal operation of GNSS receivers even in the presence of multiple jamming sources, delivering reliable anti-jamming performance in a compact form factor.

AX14 Anti-Jam CRPA System can be deployed in various flexible configurations, and is fully compatible with both civil and military GPS receivers for land, sea, air platforms (including small unmanned aerial systems) and fixed installations. The product integrates an embedded GNSS receiver that supports all global satellite constellations.

2. How It Works

AX14 mitigates RF interference by creating targeted nulls in the antenna gain pattern toward the direction of jamming sources, providing significant anti-jam protection even in dynamic multi-jammer scenarios. The system outputs a protected, standard Radio Frequency (RF) signal that is completely free from jamming, and is suitable for direct input to both modern and legacy GNSS receivers without additional modification.

3. Key Benefits

  • Immediate availability for urgent operational and deployment needs
  • Simple, tool-free assembly for easy installation or in-field retrofit
  • Full compatibility with all types of external GPS receivers and vehicle navigation systems
  • Minimal integration training required for fast deployment
  • Ultra-lightweight design at only 225g
  • Ultra-compact size of 100×100×23mm for space-constrained platforms
  • Superior interference suppression performance in a small footprint

4. Application Areas

  • Fixed Winged Aircraft
  • Rotary Wing Aircraft
  • Unmanned Autonomous Systems (UAS), especially small/lightweight UAVs
  • Armored Vehicles
  • Naval Platforms, Coast Guard Platforms
