Description

1. General Description

The AX22 GNSS navigation anti‑jamming antenna is a satellite navigation anti‑jamming antenna specially designed for FPV platforms. AX22 Anti‑Jam CRPA System supports critical missions by providing stable, jam‑free GNSS signals for size‑constrained unmanned systems.

Equipped with a high‑precision 2‑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 for FPV and other lightweight unmanned platforms.

AX22 Anti‑Jam CRPA System can be deployed in various flexible, space‑saving configurations, and is fully compatible with both civil and military GPS receivers for land, sea, air platforms (including unmanned aerial systems) and fixed installations. The product integrates an embedded GNSS receiver that supports all global satellite constellations.

2. How It Works

AX22 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 single wideband jammer scenarios common in FPV operations. 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

  • Proven, reliable anti‑jamming technology
  • Extremely low cost for high‑volume FPV and UAV applications
  • Ultra‑lightweight design for weight‑sensitive FPV platforms
  • Simple assembly for easy installation or in‑field retrofit on small unmanned systems
  • Full compatibility with all types of external GPS receivers and vehicle navigation systems

4. Application Areas

  • FPV and other size‑constrained unmanned system platforms
  • Fixed Winged Aircraft
  • Rotary Wing Aircraft
  • Unmanned Autonomous Systems (UAS)

FAQ

What is the core difference between the AX22 and other 4/8/11/16-channel anti-jamming systems?

The AX22 is specifically designed for FPV and size-constrained unmanned platforms, featuring a 2-array CRPA design that delivers reliable anti-jamming performance at an extremely low cost, while 4/8/11/16-channel systems are optimized for heavy-duty, high-value platforms with more demanding multi-jammer suppression requirements. The AX22 is the most cost-effective solution for high-volume FPV and lightweight UAV applications in our product line.

Why is the AX22 the best anti-jamming solution for FPV platforms?

The AX22 is purpose-built for FPV operations, with an ultra-lightweight, compact design that fits the strict weight and size constraints of FPV drones. It delivers reliable anti-jamming protection against the common single wideband jammers encountered in FPV racing and freestyle operations, while maintaining an extremely low cost for high-volume deployment.

How many jammers can the AX22 suppress with its 2-array CRPA design?

The AX22 is equipped with a 2-array CRPA antenna, which can create up to 1 simultaneous targeted null in the antenna gain pattern, providing effective suppression against 1 spatially diverse broadband jammer, which covers the vast majority of jamming scenarios encountered in FPV and lightweight UAV operations.

What is the key advantage of the AX22 for size-constrained unmanned systems?

The AX22 features an extremely compact, lightweight design with a weight of <110g and a power consumption of <7W, making it ideal for installation on small FPV drones and other size/weight-constrained unmanned systems where larger, heavier multi-channel anti-jamming systems cannot be deployed.

Is the AX22 compatible with both civil and military GPS receivers?

Yes, the AX22 is fully compatible with all types of civil and military GPS receivers, as well as standard vehicle, aircraft, and ship navigation systems, and can be easily integrated into both new and existing FPV and unmanned platforms with minimal modification.

How easy is it to install the AX22 on an FPV platform?

The AX22 features a simple, tool-free assembly design that allows for easy installation or in-field retrofit on FPV drones and other unmanned systems. It requires minimal integration training, making it accessible for both professional and hobbyist FPV users.

What are the key physical and electrical specifications of the AX22?

The AX22 has an ultra-compact size, a weight of <110g, operates on 12V DC power, has a power consumption of <7W, and an operating temperature range of -40℃ to +70℃, adapting to the harsh environmental conditions common in FPV and unmanned system operations.

Does the AX22 support all global satellite constellations?

Yes, the AX22 integrates an embedded GNSS receiver that supports all major global satellite constellations, including GPS, Galileo, BeiDou, and GLONASS, ensuring wide compatibility with different navigation systems worldwide.
