Why Are There Multiple 4-Element CRPA Models?

Why Multiple Models Exist

Different missions require different levels of GNSS protection.

Some platforms prioritize ultra-low SWaP, while others demand maximum anti-jamming and anti-spoofing performance in contested environments.

Our 4-element CRPA portfolio is designed to match real-world operational requirements — not just specifications.

Mission-critical autonomous systems

In practice:

  • Smaller UAVs prioritize weight, size, and power consumption.
  • Tactical platforms prioritize stronger anti-jamming and anti-spoofing performance.
  • Vehicle and ship systems prioritize environmental durability and voltage compatibility.
  • High-end autonomous systems require cleaner GNSS output and stronger weak-signal tracking.
  • Different customers also have different budget expectations and integration requirements.

This product segmentation allows customers to select the most suitable CRPA solution instead of overpaying for unnecessary capabilities or sacrificing mission reliability.

    Key Product Differentiation Logic
    1. SWaP vs Performance

    Smaller terminals are easier to integrate into compact UAVs, but larger CRPA apertures generally provide stronger anti-jamming and weak-signal tracking performance.

    2. Anti-Jamming vs Anti-Spoofing

    Standard CRPA systems mainly suppress interference.
    Advanced models such as AJT105S and GAP2501 additionally identify and suppress spoofing attacks.

    3. Tactical vs Industrial Deployment

    Some products focus on lightweight UAV deployment, while others are optimized for outdoor durability, wide voltage input, and harsh operational environments.

    4. Integration Flexibility

    Different platforms require different interfaces:

    • RF transparent integration
    • TTL serial integration (RS422/RS232 Optional)
    • GNSS receiver output
    • Flight-controller compatibility
