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.

The 4-element CRPA product family is divided into multiple categories to match different mission priorities:

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-SpoofingStandard CRPA systems mainly suppress interference.
Advanced models such as AJT105S and GAP2501 additionally identify and suppress spoofing attacks.
Some products focus on lightweight UAV deployment, while others are optimized for outdoor durability, wide voltage input, and harsh operational environments.
4. Integration FlexibilityDifferent platforms require different interfaces:
