Key Features
| No. | Product | Features |
| 1 | CRPA Antenna Quantity | Larger 4-Element CRPA Antenna – A physically larger antenna aperture improves signal capture, reception gain, and anti-interference spatial nulling performance |
| 2 | Dual-Frequency GNSS Support | Supports GPS L1 and BDS B1I for resilient navigation continuity |
| 3 | Anti-Jamming Immunity Direction | Up to 4 simultaneous jammer suppression |
| 4 | Anti- spoofing | Powerful Anti-Spoofing Beyond Standard 4-Element Solutions – Suppresses asynchronous, synchronous, and relay spoofing while outputting clean GNSS signals to the backend receiver. |
| 5 | Anti-jamming | 105 dB Anti-Jamming Performance – Delivers excellent protection against narrowband, broadband, pulse, sweep, and Gaussian interference |
| 6 | Multi-Platform Deployment | Ideal not only for UAVs, but also unmanned ground vehicles (UGVs), autonomous robots, unmanned vessels, and intelligent mobile systems |
| 7 | Easy Integration | Compatible with PX4, Ardupilot, Pixhawk, CUAV V5+, and other mainstream flight control ecosystems |

Typical Applications
Ideal for UAV navigation protection, autonomous platform guidance, fleet defense, critical infrastructure timing, and secure logistics navigation. For autonomous systems operating in spoofing-heavy or GNSS-denied environments, GAP2501 delivers a decisive advantage over traditional 4-element terminals through stronger anti-spoofing intelligence, better reception performance, and true multi-domain platform adaptability.
It is similar to the 8/16/32 Element CRPA anti-jamming terminal, GAP2501 fully compatible with mainstream open-source flight controllers including PX4, Ardupilot, Pixhawk, and V5+ platforms, enabling rapid integration without modifying navigation algorithms.
